One of the games that is often mentioned is Rallyman, a board game simulation of rally races for up to four players. You are trying to make the shortest time, by taking risks while speeding over bumps and sliding on curves. A regular game consists of completing three tracks or "special stages", which are built by using the modular board. You can combine dirt and snow-covered tracks of different lengths. I got this game last weekend and played a few races.

|Making a move: each die rolled equals moving one space.|
Rallyman offers a good solo challenge, and the combination of short set-up time and modular board means it can be played often: if I do not have much time, I can just make a single track instead of a regular race comprised of three tracks. I also do not see a reason why I could not draw new tracks on a large sheet of paper, if I ever come to a situation when the standard tracks are not challenging anymore.
