How to play

Each round shows a target number. Find three numbers next to each other on the board that make it.

• The three numbers must be in a straight line: across, down or diagonal.
• Multiply two of them and add or subtract the third. Any order works.
• Tap the three numbers. Your answer is sent with the third tap. Tap a number again to deselect it.
• After each round you can look at the solution. The next round starts when everyone is ready.

First wins

The fastest player gets a point.

Don't be last

Everyone has to find their own three numbers – solutions others found are marked on the board. The last player without a solution loses a point. If the target has fewer solutions than there are players, the round ends when all are taken, and everyone without one loses a point.

The board stays the same for the whole game. Every possible target comes up once, then the game is over.
