My grandfather's favorite game on The Price Is Right was Plinko.
It is such a simple game - The contestants drop a round flat disc (called a Plinko chip) from the top of the Plinko board and watch as the disc bounces off strategically-placed pegs until it reaches the bottom.
They say the game is completely random, and there is no way to predict where the disc will land. But my grandfather didn't think that was true.
He recorded every Plinko game since it was first introduced on January 3, 1983, and he thought he could accurately predict where the chip will fall based on where the contestant drops the chip.
To keep others from learning his secret, he encoded his calculations using a method I am not familiar with. I've studied them for years, but the secrets remain his secret.
So I've come to you asking for help. Please take a look at the drawings I found and see if you can make sense of them.
