Public inputs.
Reproducible results.
This website is one way in. While the contract is active, funded, and free of an emergency halt, anyone can buy tickets, settle draws and claim directly on Ethereum—even if Luckotto’s operator disappears.
Conflicting accepted results halt public actions. Someone still needs to submit transactions on time. Missed proof deadlines forfeit stakes; the owner retains freeze and recovery powers.

Check the result after settlement. If you win, your claim pays the wallet fixed on your ticket.
Do I need an account or identity check?
No. Luckotto requires an Ethereum wallet and ETH on Ethereum, with some left for gas. There is no Luckotto account, ID upload or KYC approval to play or claim. Ethereum transactions are public; KYC-free does not mean anonymous. On a phone, use your wallet’s built-in browser.
What does non-custodial mean here?
You enter from your wallet and your stake is held by the smart contract under its published rules. You do not maintain an operator account balance, and a winning claim pays only the wallet fixed on your ticket without operator approval. Stakes are locked until resolution; non-custodial does not mean you can withdraw a live ticket at any time. The owner’s freeze and recovery powers still apply. Read those controls.
Can I win more than the current ticket pool?
Yes. Choose a higher payout target to use the shared bankroll. That means lower win probability and a protocol edge, both shown in the builder. The homepage maximum is the current pool plus almost all the bankroll, before your stake, at a house edge approaching 100%. The actual payout depends on the pool, available bankroll and your edge cap at settlement; a target is not a guarantee. A solo pool-only ticket only returns its stake if settled, before gas.
When is the next draw, and how do I get paid?
Rounds close every 10,000 Ethereum blocks, roughly 33 hours. Draw inputs are normally ready about 46 minutes after betting closes; settlement still needs a transaction. Save your ticket ID and check My tickets for the result. The website attempts settlement and economical winning claims in the background, but timing and payment are not guaranteed. Anyone can settle or submit a claim; winning ETH always goes to the ticket’s fixed payout wallet.
What can I lose?
Your full stake, plus gas. Zero protocol edge is an average over settled pool-only tickets, not a promise that any ticket wins. Some rounds have no winner. Stakes are locked until resolution; if the proof deadline is missed, all round stakes go to the bankroll without a refund. Smart-contract bugs are also a risk.
The owner can freeze eligible rounds and, 365 days after a successful freeze, drain all remaining cash, including cash backing unpaid claims, refunds and bankroll shares. An inconsistency halt lets the owner drain immediately, without freezing or waiting. An independent professional audit is still outstanding. Read the security evidence and controls.
Can someone change the draw or redirect my payout?
The contract cannot be upgraded, and ticket terms are fixed when you enter. Neither the website nor a resolver can change the draw formula or your payout address. Public source and a verifiable draw make these rules inspectable; they do not eliminate contract, settlement or owner-control risks.
