Clocktowers is a game for 2-4 players in a competition to complete the most clocktowers in the city before time runs out. Players must complete the towers as cleanly as possible, making sure that mice and cats don't make the towers home. Of course there are other catches -- do you have the right height for the building and do you have the proper colored roof? Clocktowers plays in 20-30 minutes and can be played by ages 8 and up (although there's enough skill involved that kids shouldn't beat their parents too often!) This is based on the board game Capitol by the same designers.
