What are the fast Uno rules and how do they differ from the standard rules of Uno?
Fast Uno is a variation of the classic Uno card game that is played with a smaller deck and faster gameplay. The main differences between Fast Uno and standard Uno rules are the smaller deck size, which consists of only 40 cards instead of 108, and the faster pace of the game due to the reduced number of cards and quicker gameplay mechanics. Additionally, in Fast Uno, players are allowed to play multiple cards of the same color or number in a single turn, which is not allowed in standard Uno.
