Goal: Color entire tiles black or white to satisfy all diagonal clue numbers.
Tiles: The grid is divided into tile regions shown by bold borders. Each tile must be entirely one color.
Clues: Cells with diagonal lines contain numbers. → counts black cells to the right in its row. ↓ counts black cells below in its column. The count extends until the grid edge or another clue cell.
Controls: Click a cell to toggle its tile between white and black. Right-click toggles back.
Keyboard: Press H for hint, R to restart, Esc for menu.
Tilepaint is a Nikoli-style logic puzzle where the grid is divided into tile regions enclosed by bold borders. Some cells contain diagonal clues with numbers. A right-pointing diagonal clue counts the black cells to its right in the same row; a down-pointing clue counts black cells below in the same column. The count stops at the grid edge or another clue cell in the same line.
Click any cell to toggle its entire tile between white and black. Right-click (or long-press on mobile) to cycle back. The puzzle is solved when every clue number matches exactly. Each tile must be entirely one color — you color whole tiles, not individual cells.
Use the on-screen Hint button (or press H) to reveal one correct tile, Check to validate, Clear to wipe, and Restart (R) to reset. Press Esc for the menu. Earn up to 3 stars per level — solve without hints for a perfect rating.
Start with constraint-rich clues. Clues with value 0 mean the entire range must be white — that can lock multiple tiles immediately. Clues equal to the range length mean everything must be black. Find these extremes first to anchor your solve.
Think in tiles, not cells. Since tiles are all-or-nothing, coloring one tile affects every clue that touches any cell of that tile. When you commit to a tile's color, trace all the clues it touches to see what changes.
Use the green and red indicators. When a clue's range is fully colored, a small green dot means the clue is satisfied; a red dot means it's already exceeded. These visual hints help you spot contradictions before you go too deep.
Work from the borders. Edge and corner tiles have fewer neighbors, which narrows the possibilities. Solving the perimeter often cascades deductions inward through the overlapping clue ranges.
