Object: Create one or several continuous subway loops.
 
You are the civil engineer in a big city. Your task is to build one or several continuous subway loops, thereby incorporating several existing tunnel sections.
 
First click anywhere on the center board. Depending on the variant, a certain number of sections of a subway system will appear, coloured red. Also a grey section will appear at the right border. Click the board to insert the new grey section to the board.
 
You can click the given tile at the border to skip it. You are allowed to skip eight times. Red dots will appear as counters.
 
Try to create one or several loops by adding bends and straights. The loops are allowed to intersect. You can add a straight horizontal section to an existing vertical section and thus turn it into a cross intersection. You can add a bend on top of an existing bend to make a double bend.
 
Click on the 'CHECK' button to check whether you have created a set of closed loops. You win when all sections are part of some loop, otherwise you lose.
 
The other variants have a bigger board and/or more given sections.
