The game

Players start with 100 tokens, which can be purchased using Ethereum. The game offers two betting options: heads or tails, with a wager of 10 tokens per bet. Upon flipping the coin, if the player wins, their bet is doubled; if they lose, the bet amount is forfeited. Smart contracts ensure secure and transparent transactions throughout the gameplay.

No funds to play?

This coin flip Ethereum web app operates on the Sepolia Ethereum testnet. To acquire ETH for transactions, users can visit the Ethereum Sepolia Faucet, where they receive 0.5 ETH daily for testing purposes. This setup allows users to participate in the game without using real funds, ensuring a secure environment for testing and development.
