Crypto Mines — HTML5 Provably Fair Game

Crypto Mines is a sleek, self-contained HTML5 Mines game wrapped in a crypto-trading theme. Flip tiles to reveal gems and dodge the "scam candles" (bombs). Cash out whenever you like — but the longer you push, the bigger the multiplier and the higher the risk. Drop the single file on any static host and it runs instantly: no server, no database, no dependencies, no build step. HOW IT PLAYS Pick your bet and the number of mines (from 1 to 24 on a 5×5 grid). Each safe tile you flip raises your multiplier. Hit a scam candle and the round ends — you lose the stake. Cash out at any point to bank your winnings. The payout curve scales with both the number of mines and the number of tiles revealed, using the standard combinatorial Mines formula. FAIRNESS Every mine layout is generated with the browser's native crypto RNG (window.crypto.getRandomValues), with a Math.random fallback. The full board is decided before the first tile is revealed, and results are not influenced by player input. LOOK AND FEEL • Neon crypto aesthetic with animated glow, particle bursts and shake FX on a bomb • Canvas-rendered 5×5 grid with smooth flip animations • Live multiplier readout and next-tile preview • Procedural Web Audio sound effects — no audio files to host • Animated preloader • Fully responsive: desktop, tablet, portrait and landscape phones • Safe-area insets respected on notched devices BUILT TO CUSTOMISE Grid size, mine range, payout curve, colours and bet chips 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. 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. • 100% self-contained single HTML file — no build step, no dependencies • 5×5 Mines grid with adjustable mine count (1–24) • Dynamic multiplier that rises with every safe tile revealed • Cash-out at any time — risk/reward gameplay loop • Provably-fair crypto RNG (window.crypto.getRandomValues) • Canvas-rendered grid with smooth flip animations • Particle bursts, glow and shake FX on bomb hits • Procedural Web Audio sound effects — no audio files required • Live multiplier readout and next-tile payout preview • Adjustable bet chips, MAX button and manual bet input • Animated crypto-themed preloader • Responsive mobile-first layout (portrait + landscape + notched devices) • Demo balance persisted in localStorage, easy to swap for a real API • Public JS API (window.game.balance) for integration • Clean, commented, well-structured vanilla JavaScript
