Tile Fill
Color the empty tiles so every number matches how many neighbors share its color. A calm notebook-style logic puzzle with endless generated grids that slowly grow.
Tile Fill is a calm logic puzzle drawn on notebook paper. Every tile on the grid shows a number, and that number says how many of its up, down, left and right neighbors must share its color. Some tiles come pre-colored as clues. Your job is to color the rest so that every number on the board is true at the same time.
The first puzzles use a small 4x4 grid and only two colors, so you can learn the rule by trying things out. As you solve more, the grid grows up to 7x7 and the palette expands to three and then four colors, which turns each board into a real deduction exercise. Tiles that break the rule get a red outline right away, and finished tiles earn a small check dot, so you always know where you stand. Each solved puzzle adds points, with a bonus for finishing quickly, and the running total counts toward your best score.
This number logic puzzle is for players who enjoy quiet, satisfying brain teasers without a ticking clock. Tip: start with tiles marked 0, since all their neighbors must be a different color, and with corner tiles, which have only two neighbors to worry about.
How to play
Pick a color from the palette, then tap empty tiles to paint them; tap a painted tile again to clear it. Each number must equal how many of that tile's four neighbors share its color. Fill the whole board with every number satisfied to solve the puzzle and move on to a bigger one.
