How it works

Players alternate placing pieces in a straight line from the opponent's last piece.
No reversals: you can never move in the exact opposite direction of the previous move.
Every move leaves a trail. Trails cross into dead cells and squeeze the board.
Run your opponent out of legal moves — that's the win.

What's inside

Ranked matchmaking with ELO, 28-day seasons with leagues from Bronze to Master, daily quests and streaks, friend challenges and rematches, full replays, and a practice bot with three difficulty levels.

Fair by design

No gameplay advantage is ever sold. ORTOGO Plus removes ads and unlocks deep analysis — ranked duels stay identical for everyone.
