The most notable feature of Trouble is the "Pop-o-matic" dice container. This device is a clear plastic hemisphere containing the die, placed over a flexible sheet. Players roll the die by pressing down quickly on the bubble, which flexes the sheet and causes the die to tumble upon its rebound. The Pop-o-matic container produces a popping sound when it is used, and prevents the die from being lost. The captive die allows for quick dice rolls, and players' turns can be performed in rapid succession.
