Cheese and Crackers is a mini-game featured in Pajama Sam: "No Need to Hide When It's Dark Outside".
Cheese and Crackers can also be played in Pajama Sam's Games to Play on Any Day.
This mini-game is similar to tic-tac-toe (as mentioned by Sam in the first game), but with cheese and crackers instead of Xs and Os. To ask someone to play Cheese and Crackers with you, you say "havarti", and if they want to play too, they say "provolone". Sam (controlled by the player) always chooses to be cheese, so the toaster (controlled by the computer) is crackers. The game can be played on a 3x3 board, where you try to get three of your pieces in a row, on a 5x5 board, where you try to get four in a row, or on a 7x7 board, where you try to get five in a row.
