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!

I somehow won by guessing. If you want to beat him by 7 and give yourself a heart attack, then use the following numbers: 13, 26, 39, 8, 10, 40, 30, 50, 49, 27, 46, 36, 38, 28, 48, 34, 33, 42, and finally, 44. Great game if you are willing to persevere and frustrate yourself every time you lose, winning is extremely worth it.

(Just don't read my comment if you want to win with integrity. Enjoy =).)

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?

The thought process here is to take smaller numbers that block larger numbers from being taken. So 23 blocks 46, 25 blocks 50, 15 blocks 45 (along with 18 which takes 9), 21 and 14 together block 42 (21+14=35 so this is worth it) and also take 7 which blocks 49, 16 and 24 together block 48 (also worth it since 16+24=40), and 20 blocks 40. Using this strategy, you don't have to take any number in the 40s
