200 original puzzles in five levels, with routes and closed loops. Every puzzle has three progressive hints, and the full solutions are at the back.
Drag from square to square to lay track; drag back over a piece to remove it. Tap an empty square to cross it out, or switch to Cross out to mark several at once. Keyboard: arrow keys move, Shift + arrow lays track, X crosses a square out, Ctrl + Z undoes.
How to play Train Tracks
- Count. A number of 4 means exactly four squares in that row or column hold track. A bend counts as one square. When a row is full, cross out its other squares.
- Follow the printed pieces. The dark pieces are fixed. Continue the track from the sides they already connect.
- Keep one line. Every track square joins two of its sides, straight or around a bend. No branches, no crossings and no dead ends. With stations, the line runs from A to B. Without stations, it closes into one single loop.
A number turns green and is underlined when its row or column has the right amount of track. It turns red and is struck through when it has too much. Each puzzle has exactly one solution.
