A from-scratch clone of the "Chicken Road" crossing/crash game genre, built with PixiJS 8. The chicken crosses a road of numbered lanes, cashing out a growing multiplier at any step or losing everything on a deadly lane. The full round math is hypergeometric and mathematically proven RTP-neutral: expected value is identical at every step and for every cash-out point, verified by an included analytical + Monte-Carlo test script (npm run verify:rtp), which also chi-square tests that deadly-lane selection is unbiased. Outcomes are provably fair: HMAC-SHA256(serverSeed, clientSeed:nonce) determines deadly lanes via an unbiased partial Fisher–Yates selection. The server-seed hash is published before the round and the seed itself revealed after, so players can independently verify the result wasn't rigged. Ships with a pluggable outcome provider: run fully client-side for demos, or point it at your backend (documented round/step/cashout/forfeit REST contract) for real-money play. Includes 4 difficulty presets (Easy/Medium/Hard/Hardcore), animated traffic/collision layer, camera shake and particle effects, responsive layout tuned for both desktop and mobile portrait, PWA support (offline-capable service worker), and a dev QA panel for forcing round outcomes during testing (disabled in production builds). Clean, documented codebase — no dependency on or code from any original commercial build; only your own assets are used.
