Minimal Circle is a reaction-based casual game developed by Zakary Kinnaird. It is available on the iPhone platform as a full version game. The game is designed to challenge the player's reaction time and focus.

The game is simple to play. The player taps the start button to begin the clock, and then taps the screen when the second hand reaches the orange line. The player must continue to tap the screen when the hand reaches each orange line, while keeping an eye on the orange hand to know exactly where the next line will appear. The game also features leaderboards, which allow players to challenge their friends to beat their high scores.

Minimal Circle is a fun and addictive game that tests the player's reaction time and focus. It is a great way to pass the time and challenge yourself to beat your high score. Contact the developer, The Appreciative Minimalist, on their website or Facebook page to learn more about the game.
