Vertical Duel
Two students stand on opposite sides of the device. The screen splits top and bottom — each half is rotated to face its own player, so both read the same question right-side-up at the same time. Every question gets 2 minutes. Lock in a correct answer first and your rival gets only 10 seconds; if your first answer is wrong, the rival keeps the full remaining time. No hints, no calculator — the winner is decided by correct answers, then by total answering time.
