UNO Show 'em No Mercy offers 56 more maps, special rules and extremely hard action cards for the most brutal version of UNO ever!
Harder action cards such as skip all", 6 draw" and even 10 draw" make the game absolutely merciless.
Thanks to the stacking rule, players can pass the penalty (2, 4, 6, 10) to the next player until one can no longer react and then have to take all the cards!
