A new daily puzzle, plus 140 levels from easy 6×6 grids to expert 12×12. Lay one railway from A to B that matches every number.
Game
How to play
- The track enters at A and leaves at B, as one unbroken line.
- The number beside each row and below each column is how many squares the track uses in that line.
- Printed pieces are part of the answer. The track never branches, crosses itself or makes a loop.
New to the puzzle? The rules and worked example take two minutes, and the strategy guide covers the deductions that crack the bigger grids.
