Circle Sort is a vertical attention-challenge mobile game. The core gameplay involves long-pressing and staying still inside randomly appearing circular shrine areas, completing a charge check through the top arc progress bar. Each round the required hold time varies randomly between 3 and 5 seconds. The higher your score, the smaller the target circle and the harder it gets. Moving your finger out of the area or releasing it too soon counts as a mistake; 3 mistakes and the game is over. Success triggers ripple effects and flying light points, with vibration feedback to enhance the feel. The game supports pause, restart and high score tracking. With simple rules and fast-paced rhythm, it tests patience and stability while also offering strategy, perfect for short, repeatable sessions.
