Bus Escape is a planning puzzle: decide in what order to send the mixed-up buses from the lot to the stops. Waiting passengers can only board a bus of their own color, and buses seat 4, 6, 8, 10 or, for double-deckers, 12. The number of stops is limited, so sending out a bus you do not need yet can clog them. The 150 stages grow from 5 buses to 20; from stage 40 the back of the waiting line is hidden behind ? until its turn comes, and every stage is guaranteed solvable.
