About this game

Fusera is a chain reaction puzzle. Tap one microbe and it bursts. Its beam runs across the board, clears whatever it reaches, and that one bursts in turn. One tap, one cascade.

WHY IT IS DIFFERENT
• You do not move pieces. You choose where to start — then watch.
• Every level is built so that a solution exists. The game knows the shortest chain before you do.
• Three stars means you got it on the first try. Solving is easy; reading the board is not.

WHAT IS INSIDE
• Levels never run out — each one generated and checked
• Mirrors bend beams, walls stop them, twin microbes need two hits
• Five looks to unlock as you collect stars
• Fully offline — no account, no wifi, no timers
• 13 languages
• Free to play

No countdown, no lives, no pressure. Set it up in silence, then let it go.
Tap one microbe and the whole board clears. Calm offline chain reaction.

What’s new

Fixed a start-up problem: on a first install the ad system never actually started, so parts of the game that depend on it stayed silent. It now starts on its own, and keeps going even if a step does not answer.
