"description": "Attention: Time Setting for the Game\n\nWhen playing the game, please pay close attention to the time setting. The game requires an average of 2-3 moves per day. If you need to take a break, make sure to return promptly and make more than 3 moves per day to keep up with the time. Please do not keep your opponent waiting for tooooooooooooooo loooooooooooooooooooong. \n\n🍭Tips: \n1️⃣Utilize the conditional move feature to speed up the game. \n2️⃣Disqualification will occur if a player loses by timeout. \n3️⃣If disqualified by the tournament director, all outstanding games will be forfeited, which will affect the player’s ranking. \n\n🍭The following rules must be obeyed to guarantee a respectful game: \n1️⃣No pauses are allowed. \n2️⃣No vacation mode is permitted. (If a player is on vacation, they and their opponent can still make a move, but time will be suspended. Soooooooooooo, vacation mode is absolutely NOT allowed.) \n3️⃣Any player who is on vacation or has paused the game will be disqualified without further notice or reminder. \n4️⃣If you find that a player pauses the game or enters vacation mode, please send a message to the tournament director. \n\nLet us strive to be respectful players. \nWe wish everyone a pleasant game and hope to gain something from our opponents. :)",
