Merge RainBow Game

Merge RainBow is a casual puzzle and strategy game where you combine units to build a stronger army. The gameplay revolves around merging identical characters on a grid to unlock higher-tier fighters. Once your squad is ready, you place them into position and watch them automatically battle against the enemy forces.

Every round challenges you to manage your limited board space and resources. You must decide whether to spend your coins on new base units or save up for bigger upgrades. By carefully organizing your frontline and backline fighters, you can defeat increasingly difficult waves of opponents. It is a lightweight auto-battler that runs instantly in the browser, making it perfect for quick gaming sessions.

Controls

• Mouse / Touch: Click and drag identical units together to merge them. Drag units to reposition them on the board before a battle.

Tips

• Place your high-health melee units at the front of the board to absorb incoming damage.
• Keep ranged or fragile damage-dealers safely in the back row.
• Do not fill your board completely; always leave at least one empty space so you have room to buy and merge new units.
