Best Way to Use Mutation Machine in Break a Lucky Block

If you’re new to the game, it’s best to begin with common Brainrots. Mutating lower-tier units first helps you understand the system while gradually building toward rarer and more valuable mutations. It’s also important to consistently collect and store extra Brainrots in your inventory, allowing you to combine matching pairs without scrambling to find the required units.
Whenever possible, try to collect three copies of the same Brainrot. This way, you can keep one placed in your base to continue generating income while using the other two in the Mutation Machine. This strategy ensures your passive earnings never completely stop during the upgrade process.
Lastly, don’t forget to store your mutated Brainrots in your base or inventory. Higher-tier mutations are essential for unlocking even stronger versions later on, so keeping them organized will help you continue advancing efficiently.
