Got the game - unpacked and equal losgespielt. Who knows and has played Tetris or plays, it is love. The manual is short and easy to understand. The game is fast and has a high fun factor. With adults, it can easily go a bit hectic because you have to do and consider several things under time pressure. Children welcome (even at pre-school) you can easily modify the rules, then it also makes them fun. Overall - a good buy :-)
