- Fifty chapters from gentle to fierce. Every board is a maze of long, winding arrows that lock each other; find the free one first.
- One shared board every day, the same for everyone, with its own leaderboard and streaks.
- A level is three stars only without a single blocked tap. Two with half your lives, one for getting through.
- Google Play Games on Android, Game Center on iPhone. Signed in automatically when you open the game.
- No ads, no account forms, nothing to wait for. The first 100 levels are free; one purchase unlocks the other 900.
- Hand-drawn skin, a dot lattice board, sounds that stay out of the way.
