Awesome game idea. They are very slippery, but this is OK.
It is a shame that the cards in the additional cards packs are not all the same square size, ie. some sets are square (the same size as the top of the game tower), but the other sets (teen-adult, junior and divorce) are rectangulat and a different size. I would love to see all the sets have the same size as the game tower.
Also, the original game Jenga, has a 3-sided 'jig' to help build the tower easily. It would be good if the game included this. Otherwise good.
