About
Everyone secretly picks a number. An operator is rolled, the equation lands, and everyone races to answer it first. Rounds take about forty seconds and are decided in tens of milliseconds.
The host controls which operators are in the randomizer — add, subtract, multiply, divide — and the dial shows the ones in play before it lands on one. Clash mode puts two players' numbers head to head and rotates the pairing so everyone's pick gets featured; pile-up chains every number into one expression. Either way everybody picks and everybody races, so nobody is ever sitting out. Miss the pick clock and you simply have no number that round, though you can still win it.
Expressions read strictly left to right and divide answers go to two decimal places, rounded the way you would write them down. A wrong answer costs a short cooldown that escalates, so it pays to be right rather than fast; a mistyped digit costs nothing. It runs peer to peer in the browser with a relay fallback for networks that block that — no backend, no accounts, no install.
How to play
- One player hosts and shares the four-digit room code. Everyone else joins with it — no accounts, no install.
- The host sets the mode, the number range, which operators are in the randomizer, and the two clocks. Everyone sees the rules before the first pick.
- Secretly choose a whole number in range. Nobody sees it until the reveal, and the round starts once everyone is in.
- After a three-second countdown the numbers appear and the disc rolls an operator. Start working it out.
- Type the answer on the keypad and press Enter. Expressions read strictly left to right, so 47 + 8 × 3 is 165, not 71.
- Divide answers go to two decimal places. Both 2.33 and the exact 2.333 are accepted for 7 ÷ 3.
- First correct answer takes the round. A wrong one costs a short cooldown; a typo costs nothing.
