FAQ
Frequently Asked Questions
A quick guide to how Windfall Lotto works, including ticket rules, jackpot behavior, randomness fallback, NFT logic, and the donor shareholder model.
What chain and token does Windfall Lotto use?+
Windfall Lotto is positioned on Polygon and uses DAI for ticketing and jackpot accounting in the current product direction.
How much does one ticket cost?+
The FAQ presents the ticket as a fixed 1 DAI price so users always understand the entry cost clearly.
How many numbers are on one ticket?+
Each ticket contains 5 numbers, with values in the 0–99 range.
Are duplicate numbers allowed on a ticket?+
Yes. Duplicates are allowed.
Does the order of numbers matter?+
Yes. The current matching logic is order-sensitive and uses consecutive streak matching.
How does winning work?+
The contract checks the longest exact-position consecutive streak between your ticket and the winning numbers. A streak of 5 is tier 5, 4 is tier 4, and 3 is tier 3.
When do draws happen?+
The cadence shown in the docs is weekly, with draw closing targeted for Friday at 23:00 UTC.
What randomness system is used?+
The documented fallback flow is Chainlink first, then Supra, then blockhash if oracle routes time out.
Can a draw get stuck if the host is offline?+
The design aims to reduce that risk because progression actions such as closing, processing, finalizing, and opening the next draw are intended to be publicly callable.
Are all winning tiers paid in the same draw?+
No. The model described in the docs activates only one winning tier per draw, based on the highest available winner class.
How is the jackpot shared normally?+
The docs describe normal distribution shares of 80% for tier 5, 20% for tier 4, and 5% for tier 3, depending on which active tier is selected.
What is the windfall rule?+
Once the jackpot reaches the windfall trigger, the payout share can jump to 80% even if the active winning tier is only tier 4 or tier 3.
What happens if nobody wins?+
If no winning tier exists for that draw, the jackpot rolls over into the next draw.
Can ticket NFTs be transferred?+
Yes. Tickets are NFTs, so they can be held, viewed, and potentially transferred depending on the app flow.
If I buy a winning ticket and sell it, who gets paid?+
The current rule described in the docs is that the current owner claims the prize, but if the ticket was transferred, 10% of that claim can still go to the original minter.
What are shareholders in Windfall Lotto?+
The shareholder layer is a donor-based fee-sharing system. Donations can qualify addresses for a share of host-fee distributions.
Do ticket purchases go fully to the jackpot?+
No. The documented split is 90% to jackpot growth and 10% to host-fee accounting.
