* Stacking: When a player uses a Draw Two or Wild Draw Four card, the affected player may use a card of the same type to increase the penalty and pass it on to the next one in sequence.
* 7 - 0: When a player uses a 7, they may trade hands with the opponent of their choice. Playing a 0 requires all players to pass their entire hands one seat around the table, in the current direction of play.
* Jump-In (Ubisoft Connect): A player holding a card identical to the top discard may immediately play it, whether it is their turn or not.
* Force Play: When someone draws a card that matches the color/number/symbol of the top discard, they must immediately play it.
* No Bluffing: Wild Draw Four cards cannot be challenged.
* Draw to Match: If a player has no playable cards, they must draw from the deck until they get one that matches the current color/number/symbol.
