One Stroke on Paper · Walk Every Tile

Drag from tile to tile in a single stroke, visiting each one exactly once. Cover the whole board and the level is done. A warm hand-drawn paper look and a soft soundtrack — pour a cup of tea, sit down, and quietly walk the path to the end.

■ No Numbers, No Arrows
The start is never marked. Read the shape of the gaps, count the light and dark tiles, and reason out where the stroke has to begin — then take it all the way. The rule fits in one sentence; the bigger the board, the more it makes you think.

■ 500 Levels, Small to Large
Start on a little 5×5 board and grow all the way to a full 18×9 sheet of graph paper. Difficulty rises smoothly, and every level brings a new shape to solve.

■ Endless & Relax Modes
Pick a difficulty (Easy, Normal, Hard, Hell), choose whether to keep it steady or ramp it up level by level, and enjoy an endless supply of fresh boards. Relax mode has no timer — take as long as you like.

■ Daily Challenge
One puzzle a day, the same board for every player.

■ Medals & Achievements
Campaign levels award Bronze, Silver or Gold based on how fast you clear them, with 60 achievements to collect and a stats page that records every tile you've walked.

■ Comfortable Controls
Drag forward to move, drag back to undo, and press Backspace to clear the whole path and start over. A built-in tutorial gets you going in three steps.

■ 12 Languages
English, Traditional Chinese, Simplified Chinese, Japanese, Korean, French, German, Spanish, Italian, Portuguese (Brazil), Russian, Polish.

■ Play It Your Way
