Methodology
How we calculate the things that matter
Every number, ranking, and recommendation on odds.guru is built on documented math and editorial process. We publish the assumptions so you can check the work.
True Value
How we score welcome bonuses on a 3% blended-margin basis with a published reference scenario. Includes the 33× wagering-requirement impossibility threshold, per-anchor formulas, and worked examples.
House edge
How we compute the per-game expected loss ranges in /tools/house-edge. Citations to Wizard of Odds + UKGC RTP datasets. Why we show ranges, not single numbers.
Odds conversion
The formulas behind /tools/odds-converter. Conversions across American, Decimal, Fractional, and Implied Probability — and what bookmaker vig does to the implied probabilities you read.
Operator fees
Where the deposit and withdrawal fee data on /tools/fee-calculator comes from, how often we re-verify it, and what isn't included (crypto network fees, FX spread, VIP waivers).
- Soon
Platform reviews
How we research, score, and write platform reviews. The ranking criteria, conflict-of-interest disclosure, and the line between editorial and affiliate.
- Soon
Trust & ratings
Where the number on every platform card comes from — license weighting, complaint resolution, transparency, payout track record.
- Soon
Affiliate disclosure
Which platforms compensate us, what that compensation does and doesn't influence, and the wall between editorial and revenue.
New methodology pages get added here as the systems behind them mature. If you spot an error in the math or want a particular assumption better documented, open an issue.
