At first glance, the Plinko machine might seem like a simple contraption, but its design is actually quite ingenious. The machine consists of a vertical board filled with a series of pegs arranged in a grid pattern. At the top of the board, players drop a small disc or puck, which bounces off the pegs as it makes its way down. The pegs cause the disc to change direction multiple times, creating a random path. At the bottom of the board, there are several slots, each corresponding to a different prize or point value.
