I bought this game as it was on offer and it has proved to be a winner in our house. The premise is simple - get rid of your cards and score the most points. It's sort of like snap 2.0, you build piles by placing the number cards in sequence (up or down) and the one that puts the 5 on the pile shouts Ratuki and takes them. Seems simple but there's more than one pile to follow, you must always have three cards in your hand and you can only use one hand to play. And you get carried away quite quickly - hence the bruises as you try to slap down your cards at the same time as others. The game says it is for 9 upwards but my 7 year old enjoys this (and cheats quite well!); my five year old also enjoys it, but isn't yet quick enough to get his cards out so gets annoyed! So, highly recommended - simple, easy to pick up and addictive.
