Gameplay

This is your board. On it, there are 20 numbers. The numbers are all green at the beginning of each game. Your opponent has the same numbers on their board. Each player turns one number grey when it’s their turn as outlined below, or they can pass if they cannot find anything to play. The goal is to turn all the numbers grey. First player to do so wins the game.
When it’s your turn:
- Roll the dice.

- Decide on what you’re going to play. (In no particular order)
- Sum up the dice. For instance, if you roll a
2and a3, your sum is 2 + 3 =5- If either one of the dice is a
STAR(
), that means you get to pick which number from 1 to 5 that die is. For instance, if you roll a 4and aSTAR, you can pick anySumfrom5to9. Similarly, if you roll doubleSTARs you can pick anySumfrom2to10. - If neither is a six, they will be summed up for you automatically.
- If either one of the dice is a
- Pick any
Multiplierfrom1to10. - Pick the corresponding
Productfrom your board.

- Sum up the dice. For instance, if you roll a
- Press the
Speak Button.
- This is when your opponent might object to your play. See below, for details.
- If you rolled doubles (
1and1,STARandSTAR, etc), you play again. Otherwise, it’s your opponent’s turn.
When it’s you opponent’s turn:
You should always pay attention to what your opponent is doing. If you’re not careful, they can get away with wrong multiplications.
While your opponent is making up their mind, you can see what the Sum, Multiplier and Product they are planning to play.
Once they press their Speak Button you have 5 seconds object if you think they made a mistake by pressing the Zyzzer. ![]()
If you were right and they were wrong, that means you made a legal objection. In that case,
- Your opponent’s last play is reverted,
- You get to select revert an additional number from their board using
the Remove Button.
If you were wrong, that means you made a illegal objection. In that case, they get to revert a number on your board. This also means if they illegally object to your play, then you will get to revert a number on their baord!
