Stylish Multilingual Chess Clock A stylish chess clock supporting multiple languages: Japanese, English, Chinese, and Korean. Time Modes Supports four different time control modes: Standard After the main time runs out, countdown begins. If the player uses up all allotted countdown periods, they lose the game. Canadian (Premium Feature) After the main time, players must make a set number of moves within a given period (e.g., 10 moves in 5 minutes). Failing to do so results in a loss. NHK Cup (Premium Feature) Players play within a countdown. If it expires, they use a fixed number of "thinking periods." Losing occurs if the final period ends or a countdown ends when no periods remain. Fischer (Premium Feature) Each move adds a fixed amount of time (e.g., 5 seconds). The player loses when time runs out. How to Use When "READY" is displayed, press the button on either player's side to start. After that, each player presses their button to switch turns and start the opponent's countdown. If "READY" is not shown, press the reset button. Use the gear icon to set language and time control mode. Sound Features Beep sound: at game start, turn switch, 1 minute remaining, 30 seconds remaining Countdown voice: 20, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, "Time's up!" Button Colors Blue: your turn Yellow: within 10 seconds of timeout Red: time expired
