Hot Potato Timer
Pass the phone or tablet around the circle while a secret fuse counts down inside your chosen range, ticking faster and faster until it explodes. No rigged adult thumb, works offline.
Built by the AbraCalc team
How to play
- Set a minimum and maximum number of seconds for the hidden fuse window.
- Tap Start Passing to go full screen and begin passing the device around the circle.
- Watch the potato pulse and listen to the ticks speed up — the exact explosion time is never shown.
- When it booms, the screen flashes and sounds off; whoever is holding it is out for that round.
Classic hot potato needs a truly random fuse, not an adult secretly deciding who loses, and this timer solves that with genuine device randomness. Set a minimum and maximum number of seconds, tap Start Passing, and hand the phone or tablet to the circle. The exact explosion time is picked at random inside your range and never shown anywhere on screen, while the potato pulses and ticks faster the closer it gets to blowing up, building real suspense. When the fuse runs out, the screen turns to a boom with a burst of sound but never names anyone, so the group decides together who was holding it. It's ready in seconds, needs no setup beyond the two numbers, and works completely offline for road trips, waiting rooms, or classrooms.
Frequently asked questions
- Can someone peek at the code and know when it will explode?
- No. The explosion time is picked using the device's cryptographic random number generator the moment you tap Start, and it is never displayed anywhere on the setup or full-screen views.
- What's a good range to set for a group of kids?
- 10 to 45 seconds works well for most groups; shorter ranges keep rounds fast for younger kids, while a wider spread like 15 to 90 seconds adds more suspense for older players.
- Does the timer tell everyone who was holding it when it exploded?
- No, the explosion screen intentionally never names a player. The sound and visual cue signal the moment, and the group decides together who was holding the device.
