Swipe or draw one continuous line that passes through every block without lifting your finger or mouse.
You must fill every block in one go; backtracking isn’t allowed.
If a puzzle feels too complex, tap the hint icon to reveal part of the solution and it’s free.
s you complete puzzles, higher difficulty levels unlock more challenging puzzles.
The Fill is a one-line logic puzzle in which you must cover every block on the board with a single continuous stroke. The rule is easy to understand, but finding the right path becomes harder as the layouts grow more complex.
Your line has to pass through each block exactly once without lifting your finger or mouse, and going back over a block you have already filled is not allowed. If a puzzle has you stuck, a hint reveals part of the solution, and hints cost nothing. As you finish puzzles, higher difficulty tiers unlock with tougher layouts. It is completely free and designed as a short mental workout for moments like a commute or a break before bed.
Swipe or draw the line on a touch screen, or use the mouse on a computer, in portrait mode. Start from a block that has only one neighbour, since dead ends usually mark the beginning or the end of the correct path.
