Grid Paint
All gamesLeft to paint 20Painted 1 / 21Loose ends 0 / 1Deal tight
20 squares left to paint. Cursor at column 4, row 1. 2 legal steps: left to 2 ways out, right to 1 ways out. 0 loose ends, one allowed.
20 to go. 0 loose ends — a square with one way out has to be where you finish, so one is fine and two is a board already lost.
← → ↑ ↓ (or W A S D) paint the next square · Enter keeps going the way you were heading · F takes the step when only one is legal. Or click any square next to the cursor. The small number on a ◇ is how many ways out you would have from there. Click the board first, or press Tab to focus it.
