Unblock Metro

A subway train sits blocked behind a jam of street traffic. In Unblock Metro, the route stays shut until the vehicles ahead slide out of the way. Attention stays on the order of movement, since each blocked lane changes what can move next. Later boards pack more traffic into the same path, leaving less free space around the train.

How to play?

Slide the vehicles blocking the rail line in the direction each one faces. A car moves along its own alignment. The same rule applies to larger traffic units and emergency transport. Rearrange the line until the subway has an empty route, then move on to the next board.
