this is based on the standard guess who game.
while it's a good enough game in itself, there is one major flaw with it-you don't get a pack of cards with the moshi monsters on to choose your main guessing card (this is the card that usually stands at the front of the players tray in the guess who game). you have to rely on remembering what your moshi looks like or to mark it off on your own play tray with the little yellow peg provided. this does make it hard for younger players as they have to keep remembering if they should have knocked that card down when asking questions to guess the other players monster.
this comes as a DIY project, you have to put the 'flippers' on yourself as well as trying to line the small stickers up on them, this is quite fiddly and is better done by an adult.
the tray and flippers themselves are a bit flimsy so could break easily if played with a bit roughly.
had i known these facts about the game i would have thought twice about buying it.
