The goal: make your opponent cross out the very last line. Whoever takes the last line loses.
On your turn, tap a line — or drag across several — to cross out one or more consecutive lines in a single row.
Your stroke can't jump over a line that's already crossed out (or a gray stone line), and it can't span two rows.
When only one line remains, it's crossed automatically — whoever's turn it is takes it and loses.
Twists: ⛰ stone lines can never be crossed · ⭐ star lines earn bonus hint tokens · ⚡ blitz gives you 10 seconds per move · 🌫 fog hides one row's marks until you touch it · ✌️ double-turn means two strokes per turn.
Hints: you hold up to 5 tokens; one regenerates every 15 minutes. Star lines and boss wins earn extras. Using a hint caps that level at 2★ — earn 3★ by finding the winning line yourself.
Power-ups (⚡): earn 🪙 coins by winning, then spend them on 👻 Ghost Stroke (pass over crossed lines), 🔨 Stone Breaker (smash stones), 🌀 Second Wind (extra stroke), 🎲 Jinx (scramble the computer's move), and 🧊 Time Freeze. Campaign and Quick Match only — and like hints, they cap the level at 2★.
