Power Hour (also known as 21 for 21) is a drinking game where players take a shot of beer every minute for an hour.
This timer will count each minute down and sound a bell when it's time for your next shot. A counter will display the amount of shots that you have completed so you can track your progress.
You'll hear a bell when it's time to take a shot but this sound won't play in some cases. It's recommended to turn on desktop notifications so that you don't miss a shot. This only works on desktop and won't work if you're playing on your phone.
Until next shot
Congratulations, you have completed a Power Hour.
