Merge RainBow Game

Merge RainBow is a colorful auto-battler where you continuously combine identical units to build a stronger army. Every round begins on a grid where you spend your coins to spawn basic fighters. By dragging and dropping two units of the same level together, they instantly evolve into a single, more powerful unit with better stats. Once your board is set, you press the battle button and watch your squad automatically fight against the enemy team.

The strategy comes from how you position your evolved units before the fighting starts. You need to balance your board space while keeping your most important fighters alive. Winning a round earns you gold, allowing you to buy more units and merge them even higher. The difficulty scales up with each stage, requiring you to carefully plan your merges to keep up with increasingly tougher opponents.

Controls

• Mouse: Click and drag units to move them around the board or combine them. Use the left mouse button to interact with menus and start the battle.

Tips

• Protect your damage dealers: Always place your highest-level ranged units in the back row where they can attack safely without taking early damage.
• Manage your grid space: Try to merge units as soon as possible. If you fill every square on your board with low-level units that cannot be combined, you won't be able to buy new ones.
