Slime Merge: Unlock All Forms!

About Slime Merge: Unlock All Forms! — Cozy Idle Merge and Collection Game

Slime Merge: Unlock All Forms! is a cozy idle merge and collection game built around discovering 100 unique slime forms spread across 10 themed worlds. The core loop is satisfying and unhurried: buy slimes, merge matching pairs to evolve them into higher-tier creatures, and steadily work toward completing the full collection. Rare Shiny slimes generate 5x coin income, and Rainbow Joker slimes can upgrade any form on the board. A Lucky Wheel adds an extra layer of chance, while the Slime Frenzy mechanic and timed boosts keep things lively between merges. Reaching Form 100 opens Rebirth, which grants permanent income multipliers.

How to Play Slime Merge: Unlock All Forms!

The playing field is a 4x5 grid that can expand to hold up to 20 cells. Drag two identical slimes onto each other to merge them into the next evolutionary form. The Buy button at the bottom spawns new slimes onto the board whenever space allows.

Customer orders appear at the top of the screen; fulfilling them rewards bonus gems. Two timed boosts are available: a 5-minute Merge Pairs boost and a 10-minute x2 Income boost. Progressing all the way to Form 100 unlocks Rebirth, which provides permanent income bonuses.

Controls

• Drag and drop: Move a slime onto an identical slime to merge them
• Tap slime on board: Earn extra coins and charge the Slime Frenzy meter
• Buy button (bottom): Spawn a new slime onto the grid
