Paid link. Niekie may earn a commission if you sign up through it. The score is computed before any of that and cannot see it, so a commission cannot move this operator up or down. How we score.
Does Winna pay out?
Yes, we have watched it happen. Between 30 March 2026 and 8 August 2026 we observed 231 transfers leaving Winna's wallets on 47 separate days, across 4 addresses on 2 chains.
| Days money left their wallets | 47 |
| Outgoing transfers observed | 231 |
| Incoming transfers observed | 579 |
| Chains watched | ETH, SOL |
| Addresses watched | 4 |
These are the wallets we have attributed to this operator, so every figure is a floor and never a total: wallets we have not found are invisible to us. An outgoing transfer is money leaving, which is not the same as proof that a named player was paid. Both facts are on a public ledger and you can check the same blocks we did.
Were you paid?
A confirmed withdrawal from a real player is the strongest evidence this index holds, and it outweighs every automated check on this page. If Winna has paid you, say so and it becomes part of the score.

Terms and conditions
Fail. Terms lean heavily to the house
Winna.com operates with minimal regulatory transparency, broad discretionary powers over accounts and bonuses, and geographic restrictions that exclude major markets, presenting elevated compliance and player protection risks.
What that means in practice
- No license authority or number provided
- Operator based in Costa Rica with minimal regulation mentioned
- Extensive list of prohibited jurisdictions including major regulated markets
- Company reserves unilateral right to modify terms without prior notice
- Funds not insured or interest-bearing
- Large withdrawals subject to enhanced verification with potential delays
- Multiple withdrawals within 24 hours may incur processing fees
- Bonus abuse can result in confiscation of winnings
- Account suspension for suspected fraud with vague criteria
- Disclaimer: company makes no legal representation regarding player's right to access services

Recent activity
What has changed
Most casino reviews are written once and never touched again. Over the years I have read plenty that still quote a welcome bonus withdrawn two years earlier, and nothing on the page tells you it is stale. A score that never moves is not a steady score, it is an abandoned one. So every change we record for Winna is listed here with the date we recorded it, and you can judge for yourself how closely anyone is actually watching.

Audit ledger
Each time this score is calculated the inputs are sealed into an append-only ledger and hashed. The record below is the current one. Recompute the digest yourself and it has to match, or our arithmetic is wrong.

This is the exact JSON that was hashed, with keys sorted, which is how it is canonicalised before hashing.

To check it, hash the canonical record with keys sorted and no insignificant whitespace:
node -e "const c=v=>Array.isArray(v)?v.map(c):v&&typeof v==='object'?Object.keys(v).sort().reduce((a,k)=>(a[k]=c(v[k]),a),{}):v;
const p=require('./record.json');
console.log(require('crypto').createHash('sha256').update(JSON.stringify(c(p))).digest('hex'))"
