Doubloon Bay: HTML5 Slot Game Simulation with Source Code
A recreational casino-themed game supplied with source code for use within the licence terms. The demo uses free fictional credits only. Credits have no monetary value and cannot be purchased, transferred, sold or redeemed. There are no deposits, withdrawals, prizes or rewards of economic value.
A pirate cove at sunset
A parrot captain cheers every win from beside a gold and rope reel frame in a sunset cove. Five reels, three rows and 20 fixed lines carry emeralds, sapphires, amethysts and topaz, spyglasses, ship's wheels, captain's hats and treasure chests. The golden compass is the WILD on reels 2 to 4, and big, mega and epic wins get their own painted titles, coin showers and announcer voice.
Free spins and Locked Coins
Three or more scatters start 8, 12 or 20 free spins with a scenery of their own and a line-win multiplier that climbs from ×2 to ×5. Six or more coins start Locked Coins: the coins stay, each new coin resets the three respins, and MINI, MINOR and MAJOR coins pay their jackpot, while filling all 15 positions adds the GRAND. The BUY BONUS button starts the free spins for a price in the same free demo credits; it is not a purchase.
Rewards in demo credits
Player levels, a daily wheel and a gift button with free coins every few hours keep the session going. Every reward adds only more fictional demo credits, and when they run out the game offers a free refill.
14 languages, phone and desktop
The interface is translated into 14 languages and follows the device language. The layout adapts to phones held upright or sideways, tablets and desktops, with auto spin, turbo, a less-motion option and keyboard controls.
Your template, your hosting
Upload the game folder to any static HTTP(S) host: no database, PHP, account or server code. One settings file, editable on the host, sets languages, bets, starting credits, the RTP profile, rewards, an optional 18+ notice and events for your own page (statistics, achievements or a leaderboard of fictional scores). The complete editable source is included as a Vite project with engine tests and an RTP simulator, and the readable build is formatted for editing. A buyer guide and a customization guide for non-programmers come in English, Portuguese and Spanish.
What the licence covers
The purchase price is for a software licence, not participation in gambling. The product does not include gambling payment infrastructure, regulatory authorisation or certification for real-money operation. Real-money or other real-value gambling use is not permitted under the licence. The package includes SCOPE.md, which is part of the licence terms; the on-screen credits notice must stay visible when the game is published. Support covers bugs, installation, layout, translations, visual and audio customisation and the documented settings, not integration with wallets, deposits, withdrawals or any real-value operation.
