Is Luck Boost Worth It in Kick a Lucky Block?

Without any luck boost, Rainbow sits at 1 in 20,000 per kick. That means the expected number of kicks for one Rainbow is 20,000. At a realistic pace of maybe 500 kicks a session, you would need roughly 40 full sessions on average to see one. The 95% confidence line is about 60,000 kicks. Read that twice.

For Electrified at 1 in 5,000, expected kicks is 5,000 and the 95% line is around 15,000. Shadow at 1 in 2,000 drops those to 2,000 and about 6,000. Radioactive at 1 in 333 is already in the hundreds-of-kicks range, which is comfortable for a single long session.

A 10x luck boost roughly cuts expected kicks by 10x for rare mutations, down to where the cap kicks in. Rainbow goes from 20,000 expected attempts to about 2,000. Electrified goes from 5,000 to around 500. Shadow goes from 2,000 to around 200. Gold and Diamond are already common enough that luck does not change the feel much — Gold at base 1 in 10 can only be boosted so much before it saturates.

This is the critical point. Luck pays off on rare targets. On common ones, it is wasted.

If you are chasing Rainbow, Electrified, or Shadow and you play seriously, a luck boost is one of the best-value purchases in the game. Cutting Rainbow from 20,000 to 2,000 expected attempts is the difference between unreasonable and doable.

If you are a casual player who logs in for 20 minutes a night to push Gold and Diamond, the boost is mostly cosmetic. Your mutation rate will feel a bit better but you are not going to catch a Rainbow either way at that session length.

Luck 25 when your weight only reaches Common and Epic zones is a waste. You are multiplying a tiny base by a big number and still landing on weak zones. Weight upgrades first, then zone reach, then luck. In that order. Flip the order and you will feel cheated.

Luck also does nothing for zone progression. If Mythic is gatekeeping your reward ceiling, a luck pass will not change that. Save the money for weight upgrades.

Luck 1 to luck 5 is a massive jump in effective rate. Luck 5 to luck 10 is still good. Luck 10 to luck 25 is noticeably smaller per step. The cap also prevents any single mutation from eating the entire distribution, which means the boost at the top end is more about pushing the tails than improving common outcomes.

If you can pick a tier, luck around 5 to 10 is the sweet spot for most players. Stacking to 25 only pays off if you are grinding a top-tier target in an end-game zone.

This is exactly what the kick simulator is for. Pick your target mutation, move the luck slider, and watch expected kicks drop. Try luck 1, then 5, then 10, then 25. The curve will show you where the value stops being worth the cost.

Do the comparison before you buy. That is the simple rule.

You play 5+ hours a week and want Rainbow: buy the boost.

You play casually and want Gold and Diamond: skip it.

You are stuck on weights and zones: spend money there first.

You are curious how much it helps: the simulator at /kick-simulator will tell you in about 30 seconds.

All of these odds are community-reported estimates. The devs have not published official rates, and values may change after updates. Treat the numbers as planning tools, not guarantees. If a future patch shifts Rainbow to 1 in 10,000 or pushes it to 1 in 50,000, every conclusion here moves with it.
