What it is

A single-player Deal or No Deal game you play with USDT or USDC. One game, no slots, no sportsbook.

• Set a buy-in and claim one of 25 sealed cases.
• Open the other 24 one at a time. Each hides a prize from 0.1x to 10x of your buy-in. There is no empty case.
• After every open the Banker offers cash for your case. Press DEAL to take it, or keep opening.
• Open everything and you win what your own case holds.

A round takes about 30 seconds.

Provably fair

• Before you pick, the server shows commitment = SHA-256(serverSeed).
• Your client seed is mixed in: shuffle bytes = HMAC-SHA256(key = serverSeed, msg = clientSeed + ":" + i).
• A Fisher-Yates shuffle over the fixed 25-prize ladder gives the layout.
• When the round ends both seeds are revealed. Paste them into the verifier and it recomputes the commitment and all 25 cases in your browser.

The Banker has no hidden inputs either. The offer is the average of the remaining prizes times a published factor that rises as you open more cases. Details: how the offer is calculated.

Deposits and withdrawals

• USDT and USDC on Ethereum, BNB Smart Chain, Base (USDC) and Solana.
• Sign in with a wallet or an email. No KYC form.
• Withdrawals go only to your own account wallet (the wallet you signed in with, or the built-in wallet created for email sign-ins), so they cannot be sent to a wrong or third-party address.
• Smaller withdrawals are paid automatically. Larger ones get a manual check first.
• Deposits are free. Withdrawals pay a flat network fee shown before you confirm.

Costs

Your buy-in is the stake. The first few opens are free, later opens cost a small percentage of the buy-in, shown before each one. Full breakdown: fees explained.

Welcome to the forum. Honestly, I’m not sure if your site is actually a casino; I don’t know what kind of game this is supposed to be. I didn’t see a license, nor did I see any terms of service. I’m not sure why you haven’t included terms of service on your site. I also couldn’t find any contact information for support no email address, no Telegram channel. But I did see this:

I view all of this as unprofessional and not very trustworthy; honestly, I highly doubt that most people on this forum have actually used your site. There is a lot of information missing from the website. For instance, someone who hasn’t seen this announcement thread and discovers your site through other channels wouldn’t know whether it requires KYC, which coins it accepts, whether it allows the use of a VPN, or what its policy is regarding multiple accounts. Furthermore, the minimum deposit and withdrawal amounts are not specified not even here in this announcement thread.

Are you serious? It’s just a regular gambling game. If you want to play, go ahead, if you don’t, then dond.

Those are the basic things all gamblers who visit a casino website should check before doing anything. Though I have not checked the casino website and it UI but before anyone deposit and once he clicks the deposit button, the minimum amount to deposit suppose appears and when through there he can check the minimum withdrawal amount as well and for the KYC, base on what we have seen here in the forum, since they didn't write No KYC on the Op, I just noticed that it is a fully KYC casino. And if multiple accounting policy is not found in the ToS then the casino have to rewrite those missing information for clear understanding.
