About Yoinx

The Internet Computer's first decentralized prize game platform.

What is Yoinx?

Yoinx is a free-to-play online game platform where players compete head-to-head and in tournaments to win real prizes — grocery coupons, gift cards, ICP cryptocurrency, and Bitcoin. Built entirely on the Internet Computer (ICP) blockchain, every game round, fund transfer, and prize payout is executed on-chain with full transparency and verifiability.

Unlike traditional gaming platforms, Yoinx does not custody user funds in a centralized wallet. Each player's ICP is held in a dedicated subaccount on the official ICP ledger, derived from their unique principal ID. This means your funds are always yours — secured by the same blockchain that powers the Internet Computer network.

How It Works

Games: Join from the lobby. Free or paid with small ICP entry fee. "First to win X rounds" format.
Game Actions: Choose from Slap, Yoinx, and Sneak in a rock-paper-scissors system where each action has counters.
Prizes: Winners receive coupons, gift cards, ICP, or Bitcoin based on the game type.
Withdrawals: Crypto winnings held in your ICP subaccount. Withdraw to any ICP principal ID anytime.

Built on the Internet Computer

The Internet Computer (ICP) is a decentralized blockchain network created by the DFINITY Foundation. It enables building fully on-chain applications that run at web speed, with smart contracts (called "canisters") that execute transparently and cannot be tampered with.

On-chain game logic

Every round outcome computed and stored on the blockchain

Subaccount custody

Deposits and withdrawals use the standard ICP token protocol

HTTP outcalls

Canister communicates with Supabase for off-chain data
