Monster Hide and Seek

From BoardGameGeek:

Get ready to play hide and seek with monsters - but they won't just stay where they were. They will appear here and there in the blink of an eye, so you might need to use candies to attract them and catch them! Monster Hide and Seek is a memory game that uses double-sided monster cards to trick your memory. On your turn, flip any two monster cards. If the flip sides match, you win the cards. If they don't, simply put them down WITHOUT flipping them back. Do you remember what's on the other side of these two cards? Don't let your memory fail you!
