Okay so I have made a game, it's a grid 10x10 going from 0-99. I need to find out the odds going up from 1 to 9 numbers. 9 is the limit or else it's possible for them to go in a diagonal line accross the board and lose every time. That's because after 5-10 seconds a line will appear destroying 10 blocks going vertically or horizontally. So there's a 1-100 chance any number will be chosen, then there's a 50/50 chance it will go vertically or horizontally, if I chose just the number 0 do I have a 10% chance to lose? Because there's a 1% chance right off the bat it will get chosen, then 18% chance one of the blocks adjacent to it will be chosen, then the 18% halves because it can got in the other direction. Can someone check my math or give me a way to figure this out please? You can play a demo of the game here to understand better: http://codepen.io/sotacan/pen/MeKEjY Click on 1-9 numbers and just hit confirm, then wait for the line to fully appear.
