The brief

Develop a physics engine based Plinko browser game for a major promotional campaign with multiple prize routes and coupon print flow.

The hard problem

Make the physics feel fair and fun, while the prize logic stays in control of every drop.

What I built

01Engineered the game's physics environment using Matter.js, precisely defining the world boundaries and programmatically generating all static objects, including pegs and bumpers, from coordinate arrays.
02Architected a complex, multi-state user journey, handling conditional routing for win/loss scenarios and prize claims.
03Developed and styled the complete user flow, including interactive modals, animated win screens with a JavaScript confetti library, HTML emails.
04Implemented a custom-styled, cross-browser compatible print dialogue screen for prize coupons.
