Slimes: Evolution

About Slimes: Evolution

Slimes: Evolution is a relaxing idle merge game where dropping two identical jelly slimes together produces a new, bigger form. The goal is to work through 6 hand-drawn worlds — Blooming Meadow, Kingdom, Ocean, Volcano, Heavens, and Space — and discover all 30 slime forms, ranging from a tiny Droplet all the way up to the mighty Slime God. Each world comes with its own music, background, and merge sound, giving every stage a distinct feel. Coins accumulate even while away, and unlocking 5 income-boosting skins, spinning the lucky wheel, and completing 23 achievements keep the loop engaging well beyond the first few merges.

How to Play Slimes: Evolution: Merge, Evolve, and Unlock New Worlds

Spawn slimes by tapping the box — tapping more rapidly speeds up the process. Drag any slime onto an identical one to merge them into the next evolutionary form. Higher forms generate more coins per second, so pushing merges forward directly increases passive income.

Spend coins on upgrades to strengthen your slime box. Complete quests to earn gems, and open the evolution map at any time to track which of the 30 forms have been discovered. Reaching the final form of a world unlocks the next one and grants a permanent +20% income bonus. Rebirth is also available, trading progress for essence that accelerates earning speed.

The lucky wheel offers additional rewards, and 5 skins each provide an income boost when unlocked. With 23 achievements to chase and quests supplying a steady stream of gems, there is always a short-term target alongside the longer journey toward Slime God.

Controls

• Mouse or Touch — Tap: Spawn slimes from the box (tap faster to speed up spawning)
