This is a simple game of picking the correct one (green). Losers are in red.
This is my spin on Othello, and tic tac toe.
Pick all the green ones, before getting all the red ones.
As you advance, grids go from 2, to 2x2, 3x3, 4x4, etc.
As you can see, it's a fifty chance, of getting the right one.
Get them all the green ones, before all the red ones, and you will advance
