Rebirth Skip
99 RobuxLets you trigger your first rebirth without hitting the 1,000 Kick Power requirement.
Mutation Luck — closer look
Mutation Luck is the more economically interesting of the two. It doubles your mutation chance permanently — so every kick from now on is twice as likely to roll a Gold / Diamond / Plasma / Molten / Radioactive 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's 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.
- You can survive the tsunami consistently — buying Mutation Luck and then losing every mutated Brainrot to the wave is a bad deal.
Practical rule of thumb: buy Mutation Luck once you're comfortably running Epic+ zones with good Run Speed and you know you'll keep playing.
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're 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.
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 ourselves and they are not consistent across sources. When the in-game pass list is published or screenshotted by an authoritative source, we'll add them with a verification date.
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. 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.
