Open Lost Island Case StudyHow We Built Lost Island for Rush Social LLC
A Full Production Slot — Live on Stake
Lost Island is a complete 5×4, 12-line jungle adventure slot with free spins, coin Hold & Spin, expanding wilds, jackpot tiers, and a certified 96% RTP math model — built under contract with Rush Social LLC, and now approved and live on Stake.
Math + Client + Platform — One Stack
Python math SDK, TypeScript client contracts, and a Svelte/PixiJS frontend built as one system. Spin books, bonus modes, and UI state stay aligned from simulator to live play.
Compliance-Aware From Day One
Stake Engine certification envelopes, wincap rules, feature disclosure, mobile HUD polish, and operator feedback cycles were design inputs on this build — not post-launch fire drills. It cleared Stake's approval review with all six bet modes returning COMPLIANT on the published-books math audit.
