A round timer tracks both total elapsed time and individual round durations. Unlike a countdown, it counts up — you press a button to mark the end of each round. Ideal for games like Twilight Imperium, Terraforming Mars, and Gloomhaven.

Start the timer when the round begins, and press Round Reset when it ends. The total timer keeps running across all rounds while you see individual round durations. This helps organizers stay on schedule.

Twilight Imperium games can run 4-12+ hours, so a round timer is perfect. It tracks total game time and individual round durations without limits. Many TI groups use it to set soft time targets per round.
