What we rate

Payout reliability

Do winners actually get paid, every time, without having to chase an owner in Discord? The single thing that matters most.

25%
weight 3.5

Track record

How long it has run, who is known to be behind it, and what the community says happened the last time it went down.

21%
weight 3

Provably fair

Verifiable seeds you can check yourself, a published house edge, and results that hold up when you audit them.

18%
weight 2.5

Withdrawal speed

How long between hitting withdraw and the locks being in your world, including at peak hours.

Site & support

Whether it works on a phone, stays up under load, and whether anyone answers when something goes wrong.

What a rating means

85–100
LEGENDARY

Games check out and the winnings come back out. The best of them.

70–84
SOLID

Good to play on, with something on its page worth reading first.

50–69
MIXED

Playable, but there is a catch and it is written down.

0–49
RISKY

Something is wrong here. Read the page before you stake anything.

The badge is a separate call

Every listing carries a badge — TRUSTED UNVERIFIED AVOID that is our verdict, not arithmetic.

It is kept apart from the rating because the two can point different ways. A site can run genuinely good games and still be one we would tell you to leave alone. Anything marked AVOID drops to the bottom whatever it rated, and never appears on the promo codes page entirely.

What a rating misses

A rating describes the site we played on, on the day we played on it. The failure that costs people locks — an owner quietly stopping payouts — does not announce itself and does not change the games first.

Criteria we have not judged are excluded rather than counted as zero, so a site we are part-way through does not carry a fake bad rating while we finish. Read staying safe before you deposit anywhere, including at the top of the board.
