Create or join a game room\n2. Wait for other players to join\n3. Play cards matching the top card's color or value\n4. Use special cards to skip turns, reverse direction, or make opponents draw cards\n5. Call \"UNO\" when you have one card left\n6. First player to play all their cards wins\n\n## Game Rules\n\n- Players take turns playing cards that match the top card's color or value\n- Special cards:\n - Skip: Next player loses their turn\n - Reverse: Reverses the direction of play\n - Draw 2: Next player draws 2 cards and loses their turn\n - Wild: Player chooses the next color to be played\n - Wild Draw 4: Player chooses the next color, and the next player draws 4 cards and loses their turn\n- If a player cannot play a card, they must draw from the deck\n- Players must call \"UNO\" when they have one card left\n- First player to play all their cards wins the round","children",[],[82],"659e4e92-325b-11f0-bdb6-569c3dd06744","shared","2cba5d76-74e2-411d-980a-0d61194033f0",2,["D",1747402857670],[97,98],[91],{"_36":106,"_13":107,"_39":108,"_41":92,"_43":44,"_45":109,"_47":48,"_49":110,"_17":51,"_52":53,"_54":111,"_56":57,"_58":-5,"_87":112,"_18":113},{"_36":99,"_13":100,"_39":101,"_41":92,"_43":44,"_45":93,"_47":48,"_49":102,"_17":51,"_52":53,"_54":103,"_56":57,"_58":-5,"_87":104,"_18":105},"659e3646-325b-11f0-bdb6-569c3dd06744","types.ts","659e36f0-325b-11f0-bdb6-569c3dd06744",["D",1747402857670],"// Card colors\nexport type CardColor = \"red\" | \"blue\" | \"green\" | \"yellow\" | \"wild\";\n\n// Card values\nexport type CardValue = \n | \"0\" | \"1\" | \"2\" | \"3\" | \"4\" | \"5\" | \"6\" | \"7\" | \"8\" | \"9\" \n | \"skip\" | \"reverse\" | \"draw2\" | \"wild\" | \"wilddraw4\";\n\n// Card interface\nexport interface Card {\n id: string;\n color: CardColor;\n value: CardValue;\n}\n\n// Player interface\nexport interface Player {\n id: string;\n name: string;\n hand: Card[];\n isActive: boolean;\n calledUno: boolean;\n}\n\n// Game state\nexport interface GameState {\n gameId: string;\n players: Player[];\n deck: Card[];\n discardPile: Card[];\n currentPlayer: number;\n direction: 1 | -1;
