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.
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.
