Marimo Merge
A brain-teasing merge puzzle!
Free · Designed for iPad. Not verified for macOS.
Marimo Merge is a physics merge puzzle game where you drop cute marimo (green algae balls, moss balls) into an aquarium and combine those with the same numbers to grow them bigger and bigger.
The rules are simple, but creating large marimo requires careful thinking, and the satisfying merges and addictive chain reactions give the game surprising depth.
● Basic Rules
Tap to drop marimo into the field (aquarium) from above.
Before dropping, the marimo automatically moves left and right—tap the screen at the right moment to place it where you want.
Each marimo has a random number (1, 3, 9, …). When three marimo with the same number come together, they merge into a larger marimo with a higher value.
Repeat this to create bigger marimo and earn points by growing them or reaching target sizes and clearing them from the tank.
The game ends when five marimo overflow from the field.
● Special Actions
+ Hold
You can hold one marimo before dropping it.
By choosing when and which number to drop, you can avoid creating unnecessary gaps and grow your marimo more efficiently.
+ Shake
After dropping several marimo, you can shake the entire tank.
This can send separated marimo flying together or force near-misses to merge—potentially saving you from tricky situations.
● Game Modes
+ Max 2187 Mode
When a marimo reaches 2187, it can be cleared from the tank.
Clearing creates space, allowing you to continue merging and score even higher.
+ Max 6561 Mode
The maximum value increases to 6561 (three 2187 marimo merged).
Enjoy a more challenging and strategic merge puzzle experience.
+ Max Unlimited Mode
Marimo never disappear, no matter how large they become.
See how big you can grow them!
● Rankings
Compete with marimo masters around the world for the highest merge points.
Aim to become the ultimate marimo master!
