What are Hurdles?

The Hurdle mechanic makes the races more unpredictable!
The first four cards of the race are hidden hurdles. As the race progresses, if all four Aces have passed a given hurdle, that hurdle is revealed. The suit of the hurdle card causes the corresponding Ace to move one step backward, which can dramatically change the outcome of the race.

How are payouts calculated?

Hurdle Derby uses a pari-mutuel betting system. This means all bets go into a single pot. After the treasury takes its fee, the remaining pot is shared among all the bettors in that race, proportional to how much they bet. If you placed 10% of the total bets on the winning suit, you receive 10% of the prize pool.

What are the fees?

Hurdle Derby takes a 10% fee from the total prize pool of each race. These fees are used to pay for the game's operational costs, and contribute to the next (future) weekly jackpots, creating a self-sustaining ecosystem. However, this feature is still in the works.

How do I claim my winnings?

After a race is complete and all payouts have been processed, all bettors get a notification, when you click this, you're taken directly to that race. Here you can see the results and claim any winnings. These are transferred directly to your wallet.

Is there a time limit to claim winnings?

Yes. To ensure the treasury remains healthy and funds are not locked forever, there is a time limit to claim your winnings.

• Hourly game wins must be claimed within 7 days (168 hourly races).
• Weekly game wins must be claimed within 6 weeks.

Can I donate to the weekly jackpot?

Yes! However, this is not implemented yet. In the future, the more the community donates, the bigger the prize pool will be for everyone. As well as fees and losses from the hourly games are contributing to the jackpot.

How do I know the game is fair?

The game's fairness is guaranteed by two key features:

• On-Chain Logic: The entire game, from placing bets to simulating the race, runs on a public smart contract. Anyone can view the code to verify that the rules are being followed exactly as described.
• Commit-Reveal Randomness: A secure "Commit-Reveal" scheme for randomness. The automated keeper first commits to a secret number by publishing its hash on-chain before the race is simulated. After the race, it reveals the secret number. The contract verifies that the revealed secret matches the original hash, guaranteeing that the randomness was not tampered with after bets were closed.
