Each round, each player chooses a number.

When every player has chosen a number (or the timer expires), the round ends, and players win if the sum of chosen numbers matches their assigned number after modular reduction.

Teams or players are assigned numbers sequentially starting from 0.

Time Control

Intermissions last up to 5 seconds, ending early if all players are ready.

Each round is 3 seconds long.


Inverted (switch winning and losing, default: off)

Winners and losers are swapped.

Random (default: off)

A random number is added to the result.

Teams (default: 0)

If nonzero, players randomly fill teams rather than being assigned a unique number.

Team sizes are approximately equal. The size of the largest team is at most one plus the size of the smallest team.
