How to play
- Set how many seconds students should have to choose a corner.
- Tap Start Round and watch the countdown while students move to a corner.
- When time runs out, all four corners pulse together during a short drumroll.
- One corner lights up as the winner — students standing there stay in the game.
Set how many seconds students get to move to a corner, then tap Start Round. A big countdown gives everyone time to walk to corner 1, 2, 3, or 4 while you watch the room instead of a stopwatch. Once time is up, all four corners pulse together in a short suspenseful drumroll before one lights up as the chosen corner, and anyone standing there is still in the game. It runs the classic four-corners elimination game entirely hands-free, so a teacher can call rounds back to back without doing the random picking themselves or arguing about which corner was actually called. Everything happens in the browser with no app, no login, and no data leaving the device.
Frequently asked questions
- Can the corner be predicted from how the screen flashes?
- No, all four corners pulse together in the same rhythm during the drumroll, and the winning corner is chosen at random only after the drumroll ends, so there is no visual pattern to read ahead of time.
- Can I run rounds back to back for elimination play?
- Yes, tap Play Again after a corner is revealed to immediately start a fresh countdown, which works well for standard four-corners elimination where students leave the game after being caught in the chosen corner.
- Does every corner get picked about equally often?
- Yes, each round draws a fresh random corner with equal odds for all four, so over many rounds no corner is favored over the others.
