Set the score.
Send it.

One shared question sequence. One run each. Your rival has to beat your number.

1. The host sets the rules. Any mix of grades, clock on or off. Locked for both players.
2. Same questions. Both players get the identical sequence, in the same order.
3. One miss ends your turn. So does the clock, or leaving the page.
4. Beat it to win. Player two must go higher. A tie is a draw.
