Flippin Monsters is a card game that employs both deck-building and memory mechanics. Players are given 10 starter cards and cards will be in the middle to capture. The starter cards are placed faced down and apart from each other. On the player's turn, they can flip over any 5 of these cards they wish to help them purchase new cards or to earn points. While some Monsters allow you to purchase other Monster cards, others give you actions like being able to flip over another card or flip over an opponent's card. The trick is remembering where you left that one Monster that allows you to do that one action you really need.
