According to the information I found on the Play Store, this game was released on June 04, 2025, and the latest update was on April 24, 2026.
The game involves arranging gears to summon troops; number gears act as multipliers for the machine’s spins, character gears serve as troops, and item gears provide support in the form of attacks, buffs and stuns.
It’s actually military-themed, but to me it’s more like a robot war. The difficulty level is easy; there are forced adverts,
and the in-game currency (Green crystal) is used both during and after battles. Each character has an ultimate skill with a cooldown; there are four ultimates with different cooldown times, and they unlock based on your account level.
Total size when I play this game is 382 MB.
Don’t forget to clear the game’s cache once you’ve close the game.
Doesn't have a link account feature, so not sure if your progress is saved.
