Challenge a friend to the same grid — one link, one 5-character code, first to finish wins.
Pathfill is a number-path duel you can play head-to-head, solo, or as a shared Daily puzzle.
Draw one continuous line that starts on 1, reaches every numbered clue in order, and fills every
cell of the grid exactly once. Move up, down, left or right — never diagonally. One board, one
unique solution.
Race a friend — free, and never ad-taxed:
• Send a link, show a QR, or read out a 5-character code.
• You both race the same grid; the first valid complete path wins.
• Joining is always free — whatever size your friend hosts — and a rematch is one tap, never
gated behind an ad.
Play your way — all free:
• Solo — unlimited 6×6 and 8×8 grids, Classic or Mystery, at your own pace.
• Daily path — everyone gets the same 6×6 Classic board; keep your streak.
Two ways to read the clues. Classic shows every number. Mystery hides some as ? — same
single solution, more deduction.
Calm and fair. No account, no sign-in. Your rival’s board is never shown mid-race — only shared
progress (percent of cells filled). Ads are non-personalized by default and never interrupt a
rematch; stats and streaks stay on your device.
Optional extras. Remove ads, or unlock Extra Boards (5×5 quick + 10×10 large) for solo and
hosting. 6×6 and 8×8 are free forever, and joining a friend’s invite is always free — whatever
size they host.
Pathfill is a Queuegames puzzle.
Race a friend on one grid, or solve solo. Numbers in order, fill every cell.
