Block Link: One Line Puzzle

Draw one line. Touch every block. End on the star.

Block Link is a one-line (Hamiltonian path) puzzle. Start at the white ring and drag through neighbouring blocks — every block must be visited exactly once, and your line has to finish on the golden star.

■ Simple to pick up

- Drag to draw. Lift your finger and keep going from where you left off.

- Made a wrong turn? Drag backwards to undo one block at a time.

- No timer, no mistakes counter, no game over in the main levels.

■ Endless levels

Every level is generated with a guaranteed solution, growing from a handful of blocks to dense boards with holes that force the order of your route.

■ Today's Challenge

A brand-new course every day: 20 connected segments in one run. Your time decides a gold, silver or bronze medal — but you can always finish, so a slow day still counts. Clear every day of a month to earn that month's trophy.
