Games — Fast arcade puzzle
FİSYON
Tap a cell. Split it in two. Pop target isotopes in a chain. FİSYON reads in one tap and keeps asking for sharper decisions — an endless Reactor, a 30-experiment Laboratory, and a fresh, ad-free Daily Specimen every day.
What it is
Features
01
Endless Reactor
Manage rising pressure, time Critical Mass and Fusion cells, and reclaim the board with a Neutron cascade. One tap to read — every run a new decision.
02
30-Experiment Laboratory
Clear the whole board in the fewest moves. Carry reactions four ways with Catalysts, break Lead walls, and turn the same rules into compact puzzles.
03
Daily Specimen
A fresh, ad-free puzzle every single day — one self-contained problem to solve, no matter how the rest of your run went.
04
Element Vault
Stabilize and collect all 30 elements as you play — a growing science set that fills in the more you master the reaction.
05
Game Center leagues
Weekly and all-time leaderboards plus nine mastery achievements. Leaderboards never sell a competitive advantage — no ad or purchase buys a better rank.
06
Hands-on training
Interactive Reactor and Lab tutorials teach the mechanics by doing — not by reading walls of text before you play.
07
Honest, removable ads
Full-screen ads can be removed forever with a one-time purchase. Rewarded ads are optional — they only ever grant extra Lab moves when you ask for them.
08
Made to respect you
No account, no sign-up — progress stays on your device. Sound, haptics, reduced-motion, and full English & Turkish localization included.
Privacy
No account, no backend. Your progress lives on your device — and ads only run after you've had your say.
FİSYON has no user account and no server of its own: your reactor records and Lab progress stay on your phone. It shows ads through Google AdMob, but no ad request is made until you've responded to Google's consent message — and you can change that choice anytime in Settings. Optional gameplay analytics stay off until you turn them on.
