Fill the Gap

Guide a pixel snake through tight puzzle boards and slowly cover every open tile in Fill the Gap. This snake game focuses on logic, not speed, so you can plan routes and test ideas without a timer. Levels start out simple, then introduce layouts where a single wrong turn blocks the last few squares. Move a green snake across the grid and touch every square exactly once. The field works like a big maze made of small blocks, and your trail locks in as soon as you pass through a tile. Later stages add a second snake friend you can swap to on the same board. Switching lets you reach areas the first snake can no longer get to.

How to play?

Use the arrow keys or swipe controls to move the snake around the playing field. Plan your path so the body does not trap the head away from remaining tiles. When the second snake unlocks, switch between the two to finish complicated layouts. Both snakes share the same goal, so together they must cover all squares to clear the level. Pause for a moment on harder boards and read the grid before you move. If you restart often, notice which corners keep blocking you and change the route through that area. With careful moves, even the trickiest snake puzzles become manageable.
