Blokus, the game of champions
One of the gifts we gave our kids this year was Blokus, a board game for 2-4 players. You have to place your pieces on the board in such a way that you maximize the amount of the board that you control, while cutting off the expansion options for everyone else. The pieces you use resemble the blocks from the video game Tetris:

The game is an addictive mix of simplicity and complexity - everybody can play it, but it's not easy even for us adults.

We brought it along to Christmas dinner:

The game now has pride of place in our family library at home. Only one other game gets to live upstairs instead of living in the basement - our family Mancala set. (Hey, both of these games are math-related. That darned Chelsea has tricked us again....)
