Methodology & dataset
What the numbers mean
- Coin rate — real USD value of site balance you receive for every $1 deposited, after the site's deposit margin. 0.85 means $100 → $85 of balance.
- Bonus terms — match % / wagering multiple / house edge of the game used to clear it. Real value = bonus × (1 − wagering × edge).
- Case RTP — average return-to-player of the site's cases. Below 100% means an expected loss per open.

How we measure
Coin rates are derived from observed deposit-to-balance conversions; bonus terms from each site's published promotion pages; RTP from published case odds where available, otherwise a conservative estimate. Figures are point-in-time and re-checked monthly.
Independence
The formulas are identical for every site — only each site's own inputs differ. We take no payment for placement, publish no promo codes and use no affiliate links. If that ever changes, this page will say so first.
