Company Description:
Winnables.com is on a mission to re-imagine iGaming through full on-chain transparency. We believe players deserve provably fair odds, transparent math, and no black-box RNGs.

All of our games are designed and engineered 100% in-house by a small, senior team that blends game design, cryptography, and smart-contract security. We currently operate two flagship experiences:
Raffles – transparent prize drawings where every ticket lives on-chain, letting players verify fairness before and after the draw.
Loot Packs – blockchain-powered loot boxes that reveal randomized rewards with engaging pack-opening animations.
