DeepFi Games
DeepFi Games is a browser-based, push-your-luck betting dApp. Players place wagers, pick one tile per row (one hidden “poop” tile per row), advance for a higher multiplier, may cash out anytime, and bust if they hit the poop tile. Losers earn a small DRIP consolation. No on-chain program audit is requested; this engagement focuses on the web app, client logic, and any backend services the app calls.
