Jackpet is a decentralized, luck-powered pet game on Arbitrum, where players stake 0.01 ETH to roll adorable pets, compete for jackpots, and share rewards from an ever-growing on-chain prize pool—secured by verifiable randomness and dedicated to long-term charity impact.
Jackpet is a decentralized, chain-verifiable lucky pet game built on Arbitrum, designed to deliver excitement, fairness, and a strong sense of fortune to every player. By combining adorable pet-themed gameplay with transparent on-chain mechanics, Jackpet offers a fun yet trustworthy decentralized lottery experience.
Players join the game by purchasing a ticket (0.01 ETH) and may optionally select a multiplier of up to 100×, amplifying both risk and reward. In each round, 12 pets are randomly drawn from a collection of 24 pets, consisting of 3 types with 8 variations each. All randomness is powered by Chainlink VRF, ensuring outcomes are fully verifiable, tamper-proof, and provably fair.
- Ticket Fee: 0.01 ETH per game
- Initial Liquidity: The project injects ETH into the contract to bootstrap rewards
- Prize Pool Growth: 1% of each losing ticket is automatically added to a secure on-chain prize pool
- Multiplier Option: Players may choose multipliers up to 100× to increase excitement
- Fairness Guarantee: Chainlink VRF ensures decentralized, auditable randomness for every draw
The prize pool is governed entirely by smart contracts and cannot be withdrawn by the project team under any circumstances.
Player rewards are determined by the final pet combination drawn in each game. Rewards consist of two parts:
- A ticket-based payout multiplier
- A percentage share of the current prize pool
