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 lost by

😞

You tied the taxman!

Feb 13, 2023

either i've misunderstood the instructions, or they don't include the idea that when you pick a prime number, the others are struck out? all it says is that if you pick one the taxman gets its factors, and at the end the taxman gets the numbers with no factors left - but there's no clause saying how all primes after the first one are out of the game, could you add this to the instructions?

Level 44

Jan 4, 2025

primes have only two factors - 1 and itself. since you took a prime, 1 is out, so no primes have remaining factors in the game.
