Use these animated sand timers for your board game apps and games. These timers have a complete turn animation and fifteen states. As times will vary you will need to choose your frame with something similar to this
frameNumber = Math.round((currentSecond / totalSeconds) * 15); Or just set up a looping animation to abstractly display that time is ticking. Or if your game engine permits it set up a masked meter using the included empty version
