Official Card Game Trailer

About Happy Mochi, from BoardGameGeek:

Be the first to empty your hand! In Happy Mochi, all cards must be played in pairs, and you can never rearrange your hand. To play, you must follow value restrictions - unless you have two matching cards! In that case, shout "Happy Mochi!" and break all the rules! Special abilities and color-matching add an extra layer to this strategic party game, where luck and tactics go hand in hand. -description from the publisher
