In Keepsakes, players create a line of memories, competing to select, arrange, and recall those memories in order to gain the most Keepsakes, representing the player's score. Players start with two Keepsakes, and may gain or lose more as they complete challenges and recite the line of memories, represented by various face-up and face-down cards. Play ends when any player has zero Keepsakes remaining or the memory deck runs out, and whoever has the most Keepsakes wins (ties permitted). With that in mind players can opt to play cooperatively instead to attempt to gather the most Keepsakes collectively.
