Uno Flip is a version of classic Uno where one card can change everything.
Classic rules:
The goal of the game is to get rid of all the cards in your hand as quickly as possible.
Players are dealt 7 cards each, and the rest remain in the deck.
Initially, one card is turned over from the deck, starting the game. Players must play a card from their hand that matches the last played card in color, number, or symbol.
If a player does not have such a card in their hand, they draw a card from the deck. If the new card also does not match the last played card in color, number, or symbol, then the turn passes to another player.
When a player has only one card left in their hand, they must say "Uno". Otherwise, if other players notice, they draw two additional cards from the deck.
In Uno Flip, cards have two sides - light and dark.
The game starts from the light side, but when a player uses a flip card, players must flip all cards (including the deck) and continue the game this way until another flip card is used.
