I bought a version last christmas as a gift for the family, and christmas afternoon two of us sat down to 'try it out'. Several cups of tea later and many many games later we were hooked. It took a couple of goes to figure it out but after that we were locked into the 'just one more game' cycle until dinner stopped play.
The idea of the game is to try and end with all your coloured pegs on the highest possible score. The persion with the lowest scoring colour is the loser. You gain points by laying down the tiles in rows and making the colours match in lines, its very simple once you get the hang of it.
This is my second purchase of the game, get it, its worth it!
