Last Sender

Introduction

Last Sender is a game based on a countdown mechanism, managed by a smart contract hosted on the ARBITRUM blockchain.

Objective

The objective of the game is to be the last user to send a transaction to the smart contract before the countdown reaches 0 (expired). The last user to send a transaction wins 80% of the smart contract’s balance.

Rules

• The countdown has a duration of 200 seconds.
• Users can send transactions to the smart contract at any time.
• After the countdown expires, the SEND button is disabled, and the smart contract does not accept any more incoming transactions until the game is RESTARTED.
• The SEND button sends a transaction with a fixed amount predetermined by the contract owner to the smart contract.
• When a transaction arrives at the smart contract, the countdown resets and starts over from 200 seconds.
• The address that sent the transaction is set as the last sender.
• If no incoming transactions arrive, the countdown reaches 0 (expired), and the last sender wins 80% of the balance.
• When the countdown expires reaching 0 (expired), the RESTART button is activated. The first user to press the RESTART button calls the smart contract function responsible for restarting the countdown, clearing the last sender, and sending the prizes to their respective addresses.

Prizes

• 80% of the smart contract’s balance is awarded to the last winning sender.
• 15% of the balance is awarded to the contract owner.
• 1% of the balance is awarded to the user who, by pressing the RESTART button, calls the RESTART function of the game first.
• The remaining 4% remains in the balance for the next round.
