Each character carries their own opening, their own tells, and their own taunt when they beat you.
Powered by proprietary AI
Real games. Real timing. Real climb.
Every move you face — every pause, every blunder, every brilliancy — is shaped by our own machine-learning stack. Trained on millions of human games. Runs on your device.
🧠
19 neural networks
One proprietary opponent net per 100-Elo bracket — each trained on millions of real human games. Your rival at 1200 plays like a 1200. At 2200, like a 2200.
⏱️
5.6M moves modeled
Bot pacing is an XGBoost model trained on 5.6 million Lichess moves. Eleven features — eval, ply, time pressure, threats. Your opponent thinks the way a human at that level thinks.
🎯
Drills from your own games
Statistical win-probability-loss extraction picks the moments you actually fumbled. The drill replays it against a rival at your level, with an Elo-scaled difficulty window. No generic puzzles.
100% on-device. No accounts required to play. No server round-trips during a game.
How a match works
Pick a rival. Win. Climb.
No leaderboards, no chase. The board is between you and the next character on the floor.
- 0101 · Pick
Choose a championship
Eight tiers, seven floors each. Start at the street. Your save remembers the next door.
- 0202 · Fight
Sit across a real character
Proprietary neural networks tuned per Elo bracket, trained on millions of human games. Each rival's style, pace, and voice match the level they represent.
- 0303 · Climb
Beat them, the next door opens
Lose and you replay the same floor. Win and you climb. Boss at slot seven. New championship after.
No matchmaking. Pick your fight, climb the next floor. Every opponent's pace and style is driven by our own ML, not weakened in real time — fully baked, fully theirs.
Optional sharpening
Drills, if you want them.
The climb doesn't require them. But if a rival keeps beating you, every loss becomes a drill — phase-tagged, replayable, framed exactly like your real game.
- Your real blunders become missions — no puzzle hunting.
- Replay against a rival at your level — the same proprietary opponent net tuned to your bracket.
- Two master coaches unlock as you climb: Master Helena after the City, Sensei after the World.
- Skip the drills entirely and you can still beat the whole circuit.
