Tap the start node, then drag your finger across the board to claim every square. One uninterrupted line is all you get—any misstep ends the round.
Mastering Fill Line isn’t about speed; it’s about foresight. Begin each level by scanning the grid for choke points—those narrow corridors that force you into a single path. Mark them mentally before you draw. Use the edges of the board as “walls” to limit your options and force a deterministic route. When you hit a dead‑end, backtrack mentally and look for alternate entry angles. The deeper you go, the larger the grids become, turning simple 4x4 puzzles into sprawling 10x10 mazes. Keep an eye on the daily challenges; they rotate fresh patterns that test new tactics. Consistent play rewards you with unlockable skins and a steady flow of fresh puzzles, keeping the experience fresh for both casual players and hardcore puzzle addicts.
