Energy meter

A resource that moves while you are not looking

Most trackers only move when somebody taps them. This one can move on its own, which changes the kind of game you can run with it. Stamina that runs down while you are in the open. Oxygen in a diving game. A shield that recharges while nobody is hitting it. A budget of attention that empties over a lesson. The clock becomes a player, and the room has to decide what to spend before it is gone.

The rate is the whole design. At one a second a full meter lasts nearly two minutes, which is a round; at twenty it is gone in five seconds, which is a sprint. Set it to whatever makes a decision urgent without making it impossible, and remember that the pause button stops every meter at once so the game can be interrupted without anybody losing out.

The names come from the same shared list every tool here with players uses. If what you want is hit points that only move when something happens, the health bars are the page for that, and for a plain clock with nothing attached the countdown timer is quicker to open and reads from further away.
