UP vs DOWN game is a decentralized finance (DeFi) platform, which allows players to make predictions on the price of Bitcoin. Players can join pools that predict whether the price will go up or down, and invest a certain amount of Polygon (MATIC) to participate. The game uses smart contracts to ensure the integrity and security of the game's results. The final outcome of each round is determined by the expiry rate, which is based on the live market rate of the asset at the time of the round's closing. Profits are distributed to players in the form of the Polygon (MATIC) token, which is automatically distributed to their digital wallet.
