The Story
UNO Flash replaces UNO's clockwise turn order with an electronic unit that randomly selects who plays next after every card, under a selectable time limit (infinite, 4-second, or 6-second). Each player has a button that must be tapped to pass the turn onward, and a good roll of the dice can hand one player two or three turns in a row. The deck also swaps Reverse cards for "Slap" cards: playing one triggers a race where every other player must slap their own button as fast as possible.
Rule Twists vs. Classic UNO
Everything below is an official printed rule unless flagged otherwise.
Randomized Turn Order
Rather than passing clockwise, the electronic unit randomly selects which player goes next after every card played, timed by a selectable countdown. A player can end up taking two or three turns in a row.
Slap Cards
In place of Reverse cards, Slap cards trigger a race: the player who played it hits a large button, then every other player must slap their own button as fast as they can.
