THIS IS NOT A STANDALONE GAME. IT REQUIRES A COPY OF EXPLODING KITTENS TO PLAY. This is the first expansion of Exploding Kittens. Not only does this expansion allow you to play with up to 6 players, it also introduces 20 new cards. One of those cards is the Imploding Kitten, which is placed face up in the deck and when drawn leads to an inevitable explosion. You CANNOT defuse an Imploding Kitten. Plus, the game comes with a human-sized Cone of Shame turn indicator. Non-English Versions of Imploding Kittens are not compatible with English Versions of Exploding Kittens and Expansion Packs.
