About

Plinko is a classic game where the player drops a ball in a multi-row pin pyramid, where the ball bounces randomly until it reaches the payout bins at the bottom.

This project is a replication of Stake.com's Plinko game, created using Svelte, Tailwind CSS, and matter-js. This website is a fun personal project to learn Svelte, and it is not affiliated with Stake.com in any way. I don't encourage gambling, so that's why I created a free-to-play version of the game.

Benchmark

A hidden page is only available in local dev environment to benchmark the payout probabilities and expected values. I used this page to tune the parameters of the matter-js physics engine and control the expected payout.

http://localhost:5173/benchmark
