Calvin and Hobbes play checkers a lot. Hobbes usually wins and Calvin has a fit, but Calvin did win once and was dissatified with the rewards. Hobbes once told Calvin he lost 165 straight games in a row, and Calvin's spirit kicked the spirit of the checkers clear across the room. Once, they were playing checkers when Calvin's father told him that he had to go outside, so they just brought the checkers out with them and played out in the snow.
Calvin sometimes plays monopoly with Hobbes. However, they usually end up robbing each other and such. One time they made their own Chance cards for the game.
