The purple blocks meanwhile, function exclusively as Wild cards. The blocks are numbered one to four with additional blocks labeled “Reverse”, “Skip”, and “Draw Two”. Uno Stacko includes durable plastic blocks instead of cards, which are colored red, blue, yellow, green, and purple. The Uno Stacko rules differ quite a bit from the classic card game though, as it is almost an entirely different type of game. If you liked Jenga, you should also like Uno Stacko.
Uno Stacko is a fun adaption of the original Uno rules with similarities to Jenga, a block stacking game.
