The aim is to get £500 where you start at £100. If you get to £0 you lose. Type in how much you would like to gamble. This will be taken away from your money. The Randomizer will then randomly choose 1 or 2. If 1 is selected you lose that money you have gambled. If 2 is selected you will get that back plus the amount again.
I have no idea why I made this, I was just walking in the park and I started to formulate this.
