This is the most interesting block game I have ever played in my hands. It gets all the creation of the puzzle game: simple, fun, attractive and suitable to everybody (even for my 4 year old son). It is also the funniest way to train your brain and keep your mind sharp. How to play? Place the pieces into board. Game will be over if there are no space for any the given blocks below the board. Highlights: Easy to play and pleasurable game for all age. Not sure if it has a ranking system has been added to challenge with your friends, but I and my son enjoyed this brain game.
