Plinko

Plinko is a casino game in which a ball is dropped down a triangular field of pegs and settles in one of the slots along the bottom, each slot carrying a multiplier applied to the stake. The outer slots pay the most, the centre slots pay the least, and the ball reaches the centre far more often than the edges — which is the whole shape of the game. Most versions let a player set two things before dropping. The number of rows changes how many bounces the ball takes and how extreme the outer multipliers are, and a risk setting redistributes the paytable, pushing more value to the edges and less to the middle without changing the underlying drop. Neither is a decision that beats the game; both change how the outcomes are spread. The specific multipliers, row counts and maximum win differ between studios, and the game's rules screen states them. Plinko sits with crash and mines in the family of quick original games, and shares their characteristics: rounds resolve in a second or two, an autoplay setting can run many rounds without input, and the result of each drop is generated independently of the last. Many implementations publish a provably fair check, which confirms the result was fixed before the drop rather than making anything predictable.
