Plinko is a free online probability game where you drop balls from the top of a peg-filled board and watch them bounce their way to a scoring zone at the bottom. Inspired by the classic TV game show, this version features 22 rows of staggered pegs and 9 scoring zones ranging from 1x to 25x multipliers. You start with 100 points and 10 balls, with each drop costing 10 points. The center jackpot zone (25x) is the narrowest, making it the hardest to hit but the most rewarding.
Click along the top of the board to choose your drop position. The ball falls through the peg field, bouncing chaotically off pegs with realistic physics. Each peg collision slightly randomizes the ball's trajectory, demonstrating how small changes lead to dramatically different outcomes. The scoring zones at the bottom follow a bell curve distribution — balls naturally tend toward the middle zones, while the extreme edges (1x) and narrow center (25x) are the rarest outcomes. Strategy is limited since the physics are inherently unpredictable, making each drop a fresh experiment in probability.
Plinko is a probability-based game where you drop a ball from the top of a board filled with pegs. The ball bounces randomly off pegs as it falls, eventually landing in one of several scoring zones at the bottom. The center zone offers the highest multiplier (25x) but is the narrowest and hardest to hit.
Plinko is primarily a game of probability and chance. While you choose where to drop the ball, the chaotic bouncing off pegs makes the final landing zone essentially random. This demonstrates the concept of a normal distribution, where balls tend to cluster toward the center zones over many drops.
The center 25x zone is intentionally narrower than the outer zones, making it the rarest outcome. Over many drops, roughly 3-5% of balls land in the center jackpot zone. The probability follows a bell curve, with most balls landing in the middle-range scoring zones (5x and 10x).
