About
Duel Box turns one iPhone into a tiny arena. Put the phone flat between you and your rival - the screen splits in two, each side facing its player - and battle through six quick-fire duels:
REACTION DUEL - wait for the flash, tap first. Jump the gun and you hand over the point.
TUG OF WAR - mash your side to shove the line into their half.
QUICK MATH - true or false? Fastest correct answer wins.
BULLSEYE - stop the slider dead center. Closest lock takes it.
BLIND CLOCK - count the seconds in your head, release on the mark.
COPYCAT - memorize the sequence, repeat it without slipping.
Play any mode first to 5, spin the dice for a random duel, or run the full GAUNTLET - all six games back to back, one overall champion.
- Designed for two players on one shared screen - no second device, no setup
- Haptic feedback for points, fouls, and champions
- Sound effects (mutable) and satisfying confetti
- No ads, no in-app purchases, no accounts, no internet required
- Works anywhere: plane, bar, backseat, waiting room
Settle who's fastest. Best of luck to the runner-up.
