Confirmed game passes
Mutation Luck
139 RobuxPermanently doubles your mutation chance on every kick.
Rebirth Skip
99 RobuxLets you trigger your first rebirth without hitting the 1,000 Kick Power requirement.
Mutation Luck price confirmed at 139 Robux. Three independent guides — Pro Game Guides, AllThings.How and Sportskeeda — all quote 139 Robux as of 2026-05-01. We previously flagged a 349 Robux figure from a single older snapshot; that has now been resolved as a single-source outlier and the consensus price for this Kick a Lucky Block game pass is 139 Robux.
Mutation Luck — closer look
Mutation Luck is the more economically interesting of the two passes. It doubles your mutation chance permanently — so every kick from now on is twice as likely to roll a Gold / Diamond / Plasma / Molten / Radioactive / Shadow / Electrified / Rainbow Brainrot. The effect stacks on top of in-game global luck events, so a 4× luck event with Mutation Luck active becomes an 8× effective rate for you.
The reason we think it is a mid-game purchase, not a day-one purchase, is value-per-Robux. Mutations matter most when:
- The Brainrot they roll on is already in a high-rarity zone — a Radioactive Common is barely worth claiming versus a Diamond Mythic.
- You play long enough to roll dozens of mutations after buying — fewer kicks means fewer chances to amortize the 139 Robux investment.
- You can survive the tsunami consistently — buying Mutation Luck and then losing every mutated Brainrot to the wave is a bad deal regardless of odds.
- Your rebirth multiplier is already active — each mutation you land is worth double (or more) compared to what a pre-rebirth run earns from the same roll.
Practical rule: buy Mutation Luck once you are comfortably running Epic+ zones with good Run Speed and at least one rebirth completed.
Rebirth Skip — closer look
Rebirth Skip removes the 1,000 Kick Power requirement on your first rebirth. The 2× multiplier you get is the same as the standard rebirth — the gamepass only changes how soon you can press the button.
The problem with using it on day one is the same problem we cover in the rebirth guide: the 2× multiplier amplifies your existing income. If you rebirth at low Kick Power, you double a tiny number; if you push to a higher zone first, you double a meaningful one. Rebirth Skip is more useful as a way to reach your second or third rebirth faster than as a way to skip your first grind.
Honest take: most players are better off buying Mutation Luck if they are going to spend Robux at all. Rebirth Skip is fine if 99 Robux is pocket change for you and you genuinely don't enjoy the first-hour grind — just know that you are trading grind time for a worse multiplier base.
When to buy: stage-by-stage guide
The right time to buy a pass depends entirely on where you are in your progression. Using the wrong pass at the wrong stage is the most common Robux mistake in Kick a Lucky Block. This table maps each game phase to our recommendation:
| Game stage | Kick Power range | Mutation Luck (139 Robux) | Rebirth Skip (99 Robux) |
|---|---|---|---|
| First session (pre-Bone Barbell) | 0–10 KP | Skip — mutation rolls at Common / Rare zones are nearly worthless regardless of doubled odds. | Skip — you are still learning the tsunami loop. Pressing rebirth now applies 2× to an income of almost zero. |
| Early game | 10–100 KP | Skip — zone quality is still too low for doubled mutation chance to matter. | Situational — only if the first 1,000 KP grind genuinely bothers you and the 99 Robux is trivial. |
| Mid game (approaching 1,000 KP) | 100–1,000 KP | Strong buy if you are consistently reaching Epic or Legendary zones and playing 30+ min/day. | Not useful — you are so close to the threshold that natural play beats the shortcut. |
| Post-rebirth grind | 1,000+ KP × N rebirths | Best value — your rebirth multiplier and zone earnings are both higher, so doubled mutation odds pay off. | Marginal — natural rebirths are fast at this stage thanks to your stacked multiplier. |
| Endgame (Hacked / OG / Celestial) | Multi-rebirth endgame | Maximum value — Celestial-zone mutations with doubled odds during global luck events is the highest-upside play in the game. | Skip — at endgame the grind between rebirths is already fast. Spend Robux on Mutation Luck instead. |
Kick Power ranges are qualitative. Exact per-zone thresholds are not publicly documented by the developer; the table uses the weight-tier ladder from TechWiser as a proxy for progression stage.
Which pass to buy first
If you are going to buy one pass and want the most impact per Robux, the answer is almost always Mutation Luck. Here is the logic:
Rebirth Skip is a one-time convenience. Once you press your first rebirth, the pass has served its purpose. The 2× multiplier you receive is identical whether you paid 99 Robux to skip the grind or hit 1,000 Kick Power naturally. The only thing the pass changes is whether you waited.
Mutation Luck, by contrast, compounds forever. Every kick for the rest of your play history benefits from the doubled odds. A Radioactive or Rainbow mutation on a Hacked-zone Brainrot during a global luck event, amplified by two or three stacked rebirth multipliers, is the kind of roll that defines an endgame session — and Mutation Luck makes that outcome twice as likely on every single kick. Over the lifetime of a player who reaches endgame, the 40-Robux premium over Rebirth Skip returns many times over.
The one case where Rebirth Skip makes sense first: if you are a returning player who disliked the early grind on a previous account and want to skip back to the mid-game zone bracket immediately.
Free-to-play vs paid progression — what the passes actually change
Kick a Lucky Block is fully playable without spending Robux — every weight, every zone, every mutation tier is accessible to free players. The two game passes are accelerators, not gatekeepers. Here is what the progression timeline looks like with and without each pass, based on community guides and our own playthrough observations:
| Milestone | Free-to-play | With Mutation Luck (139 Robux) | With Rebirth Skip (99 Robux) | With both (238 Robux) |
|---|---|---|---|---|
| First Bone Barbell | ~5 min | ~5 min (no change — mutations do not affect early cash flow) | ~5 min (no change — skip does not affect weight costs) | ~5 min |
| Copper Plate (skip Stone Block) | ~20–30 min | ~18–25 min (mild acceleration from early mutations) | ~20–30 min (no change) | ~18–25 min |
| Iron Plate | ~45–60 min | ~35–50 min (mutated Brainrots compound at Epic+ zones) | ~45–60 min (no change) | ~35–50 min |
| First rebirth (1,000 KP) | ~60–90 min | ~50–75 min | Immediate — skip the grind entirely | Immediate — skip + faster post-rebirth climb |
| Post-rebirth re-climb to 1,000 KP | ~30–45 min | ~25–35 min (2× multiplier + doubled mutation odds compound) | ~30–45 min (same as F2P post-rebirth) | ~25–35 min |
| Endgame (Hacked+ zones) | Achievable — more grind required | Achievable — meaningfully faster due to doubled odds on endgame rolls | Achievable — same grind as F2P after the skip | Achievable — fastest timeline |
Timeline estimates are community approximations from Pro Game Guides and FindingDulcinea progression guides — not developer-published data. Actual times depend on server conditions, luck event frequency, and player skill. The pattern is clear: Mutation Luck provides accelerating value as you progress (mild at Common, strong at Godly+, dominant at Celestial), while Rebirth Skip is a one-time convenience whose value is concentrated in the first hour and then drops to zero for the rest of your play history.
Robux efficiency — cost per hour saved and value per game stage
The most practical way to evaluate a Robux purchase is cost per hour of grind avoided, adjusted for how long you plan to play. Here is the breakdown for each pass at different commitment levels:
| Play commitment | Mutation Luck value | Rebirth Skip value | Better buy |
|---|---|---|---|
| Casual (1–2 sessions, <5 hrs total) | Low — you won't play enough kicks for doubled odds to pay back 139 Robux. Each session: ~60 kicks with doubled odds ≈ 1–2 extra Gold/Diamond mutations. Not worth it. | Low-Medium — skips the first-hour grind, but the multiplier on a casual player's low-zone income is modest. 99 Robux for ~45 minutes saved. | Neither — save your Robux. Both passes need sustained play to justify their cost. |
| Regular (3–5 sessions/week, 10–30 hrs) | Medium-High — doubled odds across hundreds of kicks per week. At Epic+ zones, each extra Plasma or Molten mutation meaningfully accelerates your progression curve. 139 Robux amortized over weeks of play is strong value. | Low — the time saved (first rebirth grind, ~45 min) is a small fraction of your total play time. The pass does nothing after the first rebirth. | Mutation Luck — far better long-term value at this commitment level. |
| Daily (5–7 sessions/week, 30+ hrs) | High — doubled odds on thousands of kicks. At Godly+ zones, extra Electrified, Alien, or Rainbow mutations from doubled odds produce massive passive income. The pass pays for itself in gameplay acceleration within the first week of daily play. | Very Low — the hour saved in your first session is negligible relative to your total play time. The pass effect is consumed after one use. | Mutation Luck — dominant choice. Rebirth Skip is not worth it at this commitment level unless 99 Robux is pocket change. |
| Endgame grinder (multiple rebirths, all zones unlocked) | Maximum — at Celestial zone, a single extra Rainbow or Bacon mutation from doubled odds can define a session. The pass has been compounding for your entire play history. Every future kick benefits. | Zero — you are past the point where the skip matters. Natural rebirths are fast at endgame. | Mutation Luck — no contest. Rebirth Skip has zero value at this stage. |
Pass stacking — how Mutation Luck interacts with every other system
Mutation Luck is the more interesting pass because it touches every other progression system in the game. Understanding how it stacks — literally and figuratively — is the difference between buying it at the right time and buying it too early.
- Mutation Luck × rebirth multiplier. A mutated Brainrot's earnings are multiplied by your rebirth multiplier. A Radioactive (8×) Brainrot at 3× rebirth earns 24× base income. With Mutation Luck, you land Radioactive mutations twice as often — and every one of them gets the rebirth multiplier. Post-rebirth is when Mutation Luck reaches peak value.
- Mutation Luck × zone tier. Mutation Luck doubles your odds, but the value of each mutation depends on the zone. Doubling a 1% chance at a Gold Common is worth very little; doubling a 1% chance at a Rainbow Celestial is worth an enormous amount. This is why Mutation Luck is a mid-game purchase — the zone tier you can reach determines the actual value of doubled odds.
- Mutation Luck × global luck events. During a 4× global luck event, your mutation chance is 4× the base rate. With Mutation Luck (2× permanent), your effective rate during the event is 8× the base. The pass and the event multiply each other — the pass owner gets significantly more value from every global luck event than a free player does.
- Mutation Luck × Weather Machine. Weather Machine events add temporary mutation chances for specific tiers (Bacon 30×, Phantom 25×, etc.). The interaction is unconfirmed — community sources have not documented whether Mutation Luck doubles Weather Machine event odds or only applies to standard kick rolls. Treat Weather Machine + Mutation Luck stacking as unknown until a source tests it.
- Rebirth Skip × mutation farming. Rebirth Skip lets you start stacking rebirth multipliers sooner, which means your mutation rolls land on higher-multiplied Brainrots earlier. This is the one case where buying both passes creates synergy: Skip gets you to 2× faster, and Mutation Luck doubles the odds on every kick from that point forward. The combined cost (238 Robux) is significant — only worth it if you plan to play regularly for weeks.
ROI timeline — when each pass starts paying for itself
Robux purchases in Kick a Lucky Block do not generate Robux returns — they generate gameplay acceleration. The "return" is measured in time saved and progression speed gained. Here is when each pass reaches its break-even point in practical terms:
Mutation Luck (139 Robux)
- First session: negligible return. Your zone quality is too low for doubled mutation odds to matter. You will see 1–2 extra Gold/Diamond mutations — combined income gain under 5%.
- By Epic zone (first 30–45 min): break-even begins. Doubled odds at Epic+ zones produce enough extra Plasma/Molten mutations that your weight purchases come noticeably faster. You reach Copper Plate and Iron Plate sooner than a free player.
- By first rebirth (~60–90 min): clearly positive. The extra mutations you landed during the pre-rebirth grind mean your post-rebirth plot is stronger, your re-climb is faster, and your 2× multiplier is compounding on a higher base.
- After second rebirth: strongly positive. The pass has been active for dozens of kicks across multiple zone tiers. The cumulative extra mutations compound with your stacked rebirth multipliers. The 139 Robux has effectively bought you hours of grind time.
- Endgame: dominant. Every extra Rainbow, Alien, or Bacon mutation from doubled odds is a session-defining roll. The pass has paid for itself many times over in gameplay acceleration.
Rebirth Skip (99 Robux)
- First session: saves ~45–60 minutes of grind to reach 1,000 Kick Power. You rebirth immediately at low Kick Power, receiving the 2× multiplier on a weak income base. Net effect: you skipped the grind but applied the multiplier poorly.
- After first rebirth: the pass has served its purpose. From this point forward, it provides zero ongoing value. You rebirthed sooner than a free player, but your post-rebirth re-climb starts from a weaker position because you skipped the zone push.
- Long-term: zero ongoing value. The free player who grinded to 1,000 KP and pushed into Godly before rebirthing has a stronger post-rebirth position than the Rebirth Skip player who rebirthed at low KP. Over weeks of play, the free player catches up and surpasses the Skip player because their first multiplier was applied to a higher income base.
The bottom line: Mutation Luck is a long-term investment that gets better the longer you play. Rebirth Skip is a short-term convenience that saves one hour and then provides zero ongoing value. If you are going to spend Robux at all, Mutation Luck is the clear first choice — and Rebirth Skip is only worth considering if you value the first-hour grind skip above all else.
Free alternatives to each pass — how to get similar effects without spending Robux
Every benefit a game pass provides has a free counterpart — sometimes less convenient, but equally effective over time. Here is how to replicate each pass's effect without spending Robux:
| Pass benefit | Free alternative | How to execute | Effectiveness vs. pass |
|---|---|---|---|
| Doubled mutation odds (Mutation Luck) | Global luck events (2×, 4×, 8× server-wide boosts) | Watch server chat for luck event announcements. When one fires, drop everything and spam kicks for the full ~5-minute window. Prepare by saving your best weight for the event so you kick into the highest zone you can reach. | ~60–80% — luck events are temporary (not permanent like the pass) but produce higher effective odds during the window (up to 8× vs the pass's 2×). A player who catches 2–3 luck events per session can match or exceed the pass's daily mutation output. |
| Skip first rebirth grind (Rebirth Skip) | Weight skip strategy (Bone Barbell → Copper Plate) | Skip the Stone Block entirely. Buy Bone Barbell ($7.5K, +5 KP) as your first purchase, then save directly to Copper Plate ($500K, +50 KP). This single skip cuts 15–20 minutes off the 1,000 KP grind — at zero Robux cost. Two independent guides (Pro Game Guides and FindingDulcinea) confirm this strategy. | ~70–80% — you still do most of the grind, but the optimized path is significantly faster than buying every weight in order. The remaining 15–20 minute gap is what the 99 Robux actually buys. |
| Permanent mutation chance boost | Perfect kicks (timing bonus on every kick) | Land your kick in the green zone of the timing meter for a small luck bonus on that roll. Practice the timing until it becomes muscle memory — the bonus applies to every kick, forever, at zero cost. | ~20–30% — the Perfect Kick bonus is smaller than the pass's 2×, but it is permanent, free, and stacks with luck events. A player who lands Perfect Kicks consistently and catches events gets most of the Mutation Luck benefit without spending Robux. |
| Faster progression curve | AFK training + offline earnings optimization | Before logging off, equip your heaviest weight and leave the game running for 10–15 minutes of passive training. On login, collect offline earnings first, then immediately invest in the next weight tier. Replace weak plot Brainrots before logging off to maximize the offline cap. | ~40–50% — passive progression cannot match active play, but consistent AFK optimization across days adds up to hours of saved grind time at zero Robux cost. |
The free alternatives above are community-compiled strategies from Pro Game Guides, FindingDulcinea, and ggwtb.com. Effectiveness ratings are qualitative estimates — not developer-published comparisons. The most powerful free strategy is combining all four: use the weight skip path, land Perfect Kicks consistently, catch every global luck event, and optimise your offline earnings routine. A disciplined free player following all four strategies will outpace a pass-owning player who plays casually.
Passes we have not confirmed
Some upstream guides hint at additional Robux-priced passes for early access, plot expansion, VIP areas or 2× cash. We are not listing those today because we have not been able to verify them in-game and they are not consistent across sources. When the in-game pass list is published or screenshotted by an authoritative source, we will add them with a verification date and source link.
Avoid Robux scams
If you ever see a site offering "free Robux" for entering a code, watching an ad, or completing an offer in exchange for a Kick a Lucky Block reward — close the tab immediately. Roblox does not give Robux for outside actions, and the developer of Kick a Lucky Block does not run external giveaways. The only legitimate way to spend Robux on the game is through Roblox itself, on the experience's official Robux store.
No in-game code redemption is currently live, so if anyone offers you "codes for free Robux" they are misrepresenting the game. Until the developer enables the redemption UI, the only legitimate Robux spend tied to this game is the two passes above.
