Cash Case — HTML5 Case Opening Game

Cash Case is a polished, self-contained HTML5 case-opening game. Pick a case, hit Open, and watch the reel spin past item after item until it lands on your prize. Rarer items pay more — and the tension of a near-miss is the whole point. Drop the single file on any static host and it runs instantly: no server, no database, no dependencies, no build step. HOW IT PLAYS Choose a case tier (Mini, Low, Mid, High, Elite — editable in config) and a bet. Hit Open and a horizontal reel of items spins with a smooth eased motion, slowing down until it stops on a winning item. The item's multiplier is applied to your bet and paid out instantly. Each case tier has its own item pool, rarity weights and max win — all defined in a single config block. FAIRNESS The winning item is decided with the browser's native crypto RNG (window.crypto.getRandomValues), with a Math.random fallback, weighted by each item's configured probability. The result is locked in before the animation starts — the reel is rendered to land exactly on it. LOOK AND FEEL • Clean casino aesthetic with neon accents and glassy cards • Canvas/CSS-rendered spinning reel with motion blur, easing and a glowing pointer • Rarity tiers (Common / Uncommon / Rare / Epic / Legendary) with distinct colours and glow • Win FX: confetti, screen flash and rarity-based callouts on big hits • Procedural Web Audio sound effects — no audio files to host • Animated preloader with a case-shaking sequence • Fully responsive: desktop, tablet, portrait and landscape phones • Safe-area insets respected on notched devices BUILT TO CUSTOMISE Case tiers, item pools, multipliers, rarity weights, bet chips, colours and the pointer behaviour all live in a single config block at the top of the script. The demo balance is stored in localStorage through load()/save() — swap those two functions for your own API calls (fetch/AJAX) to connect real currency. A public window.game.balance setter is exposed for integration. No frameworks, no external requests, no third-party assets. Open index.html and play. Note: this item ships in DEMO MODE with a local balance and "virtual points only" labeling. It does not process real payments and contains no gambling backend — it is a front-end game template intended for integration into your own platform. All item icons and artwork are original / emoji / canvas-drawn for this item.
