Challenges players to complete loops of railway tracks by moving pieces around on the board.
- The objective is to complete loops of railway tracks.
- Click on a tile to select, then click on any empty space to move there.
- After a tile is moved, a new replacement tile will be placed at the old location.
- You score each time you complete a loop. The bigger the loop, the more points you score (the score scales exponentially with the size of the loop).
- Tiles forming the loop will be removed from the board.
