Adventure Fantasy Slot Development

I want a full-featured online slot machine built from scratch in an adventure-and-fantasy style, comparable to the polished real-money casino sites you see today. The core game loop, art direction, and sound design should immerse the player in a quest-driven world while still delivering the fast, familiar slots experience.

Please make sure the finished game includes:
• Bonus rounds that break away from the base reels and introduce interactive mini-games
• Free-spin sequences with multipliers or expanding wilds to keep engagement high
• A scalable progressive jackpot system that can grow across multiple player sessions or instances

The maths model, RTP settings, and volatility must be configurable so I can tweak payout behaviour during testing. Smooth performance on both desktop and mobile browsers is important, so I’m open to HTML5/Phaser, Unity WebGL, or another engine you can justify.

Artwork, UI assets, and music/sfx should be original or properly licensed for commercial use. Source code, build instructions, and a short doc explaining how to reskin or localise the game will form the final hand-off package.

If you’ve shipped slot titles before, share a link or short demo so I can see reel animations, pay-table work, and how you’ve handled jackpots in the past.
