Looking for a designer with the ability to create browser-ready slot machines built with clean HTML5 and JavaScript ([login to view URL])—no Unity, no bulky frameworks—so it loads fast and runs smoothly on desktop and mobile. I will supply the artwork and audio; you wire up the reels, pay-table logic, sound triggers, and a lightweight balance system that my back-end team can later connect to an API. An adjustable spin speed (to let the game feel deliberately “slow” when required) and an external JSON file for RTP, pay-lines, and symbol weights are essential. The code must be modular, thoroughly commented, and bundled through a standard Node / npm workflow; feel free to lean on PixiJS or GSAP if that keeps the canvas animations buttery. Deliverables • One responsive slot machine playable in any modern browser • ES6 source code with build instructions and a brief README • External config files for math, odds, and spin timing • A live demo link for testing Acceptance criteria – Original, readable code (no third-party casino engines) – Consistent 60 FPS on Chrome Mobile and Safari iOS – Lighthouse performance score ≥ 85 on mobile If you’ve shipped similar HTML5 slots before, point me to them and tell me how you handled reel math and animation timing. I’m ready to start as soon as I see a solid plan and a concise timeline. Example: [login to view URL]

Hi, this is Elias from Miami. I went through your description carefully, and I’m clear that you’re looking for a pure HTML5 / JavaScript slot machine—no Unity, no heavy frameworks—that loads fast, runs at a stable 60 FPS on mobile and desktop, and keeps all math, RTP, paylines, symbol weights, and spin timing externalized via JSON. I’ve built browser-based slot and reel-style games using Canvas + PixiJS + GSAP, where reel math is fully deterministic and animation timing is decoupled from outcomes so you can deliberately slow spins without affecting RTP. Wiring reels, pay-table logic, sound triggers, and a lightweight balance layer (API-ready) inside a clean ES6 + npm workflow is very much in my wheelhouse. I’m also used to keeping code modular, readable, and well-documented for handoff to backend teams. A few project-specific questions to lock this down: Q1: How many reels and visible rows are you targeting for this MVP (e.g., 5x3), and should paylines be fixed or configurable at runtime? Q2: Should the adjustable spin speed affect only animation duration, or also anticipation effects (reel stagger, near-miss timing)? Q3: Do you want symbol hit frequency fully controlled via weights only, or should specific reel strips be defined in JSON as well? Once aligned, I can share similar HTML5 slot work, outline the reel math approach, and provide a concise timeline. Looking forward to hearing from you. Regards, Elias

Dear Client, I build browser-ready HTML5 slot games that feel smooth, fast, and intentional on both desktop and mobile - without heavy engines or bloated frameworks. Your requirement for clean JS, externalized math configs, and controlled spin timing is exactly how I approach slot architecture. In a previous slot-style canvas project, I implemented reel strips driven by external JSON (RTP, paylines, symbol weights), decoupled animation timing from math resolution, and used GSAP for deterministic easing - maintaining stable 60 FPS on mobile Safari while allowing adjustable “slow spin” modes. Two technical questions to align early: 1. Do you want reel outcomes resolved server-side later (API-ready), or fully client-side with hooks for validation? 2. Should spin speed be globally configurable or adjustable per game mode (e.g., turbo vs cinematic)? I can deliver modular ES6 code via Node/npm, a live demo, external config files, and a concise README. Happy to share a clear build plan and timeline immediately. Warm regards,
