Number Factoring Game

This is an old math exercise often called the "Taxman". Here's how it works.

Pick a number from the board in a black circle
You get the value of the number (shown in green)
Your opponent, the taxman, gets all the factors of that number that remain on the board (shown in red)
When no more numbers remain that have factors, the taxman gets all those too!

Think you can beat the taxman? Start by clicking a number!

Congratulations!
You beat the taxman by

😞

You tied the taxman!
