Link Flow

Connect the dots. Link every pair. Fill the board.

Link Flow is a calm, satisfying pipe puzzle. Draw a pipe between each pair of matching coloured dots, never crossing another pipe, and fill every square of the board. One simple rule, hundreds of clever puzzles.

━━ 780 PUZZLES, EACH WITH ONE PERFECT SOLUTION ━━

Every level is checked by computer to have exactly one solution, so every puzzle is fair and can be solved by logic, never by luck.

• Classic: 360 levels across 12 packs, from a gentle 5×5 to huge 15×15 Master boards

• Bridges: 180 levels where pipes cross over each other on bridge tiles, one straight across each way

• Twists: 240 levels on shaped boards (hearts, rings, crosses, diamonds and more), from 6×6 up to 12×12
