Santa Claus no Takarabako is a simulator that allows the user to create custom sprite-based Christmas cards. The player can select a message, modify a walking sprite of Santa Claus and choose a background image and music to accompany the message. The secondary mode provides various random generators for gambling games, such as a quintet of dice for Yahtzee (a.k.a. Dice Poker), a spinning roulette wheel or a bingo sheet. The game does not track progress, so the players themselves must be responsible for any scorekeeping. The four games are Poker Dice, Roulette, Slot Machine, and Bingo.
