Idle Monster Merge

Merge monsters, earn stars, and grow your magical collection!

Idle Monster Merge is a casual merge game where every monster helps you produce more stars. Place monsters on the board, combine matching ones, and discover stronger new forms.

The higher the monster’s level, the more stars it produces every second.

Merge and Discover

Drag two matching monsters together to merge them into a higher-level monster. Keep combining monsters to discover new forms and increase your star income.

Build Your Monster Board

The board contains 16 spaces, and each space can hold one monster. Organize your collection carefully, keep enough room for new monsters, and decide which monsters to merge next.

Earn Stars Every Second

Monsters placed on the board continuously generate stars. Higher-level monsters produce more stars per second, helping you expand your collection faster.

Buy New Monsters

Use the stars you earn to purchase new monsters. As you progress, new monsters become more expensive, so keep merging and improving your star production.

Summon a Powerful Spirit

Activate Summon Spirit to call upon a magical beast and double your star income. Use the extra stars to purchase more monsters, create more merges, and continue your progression.
