Strategy: when to crack Lucky Blocks

Open Normal blocks immediately — the pool is Common/Uncommon, no reason to hold them. For Gold and Diamond, save your stock for mutation updates (especially Cyber Update and future events). Pools rebalance after patches and Diamond blocks have a ~4.5% Mythical rate plus a small Cyber roll chance.

Frequently Asked Questions

What are Lucky Blocks in Steal a Brainrot?

Crates that drop from special enemies or events. Opening one gives a random brainrot, mutation, or cash. The rarer the block (Normal → Gold → Diamond), the better the drop pool.

What is the Mythical drop rate from a Gold Lucky Block?

Roughly 1.2% from Gold and 4.5% from Diamond. Cyber Mutations can roll from both Gold and Diamond, slightly higher in Diamond post-April 18 update.

Where do you get Lucky Blocks?

Normal: common enemies and quests. Gold: bosses and special events. Diamond: rare drops from the Brainrot Trader, Lucky Block Bash event, and completing 7 consecutive daily quests.

Should you save Lucky Blocks or open them immediately?

Save Gold and Diamond blocks for mutation updates (like Cyber Update). Drop pools shift on patches, and blocks opened immediately after a major update have higher expected value.
