OTBB Offer Value Score
Also known as: welcome offer rating, bonus score, offer rating methodology
Definition
A bookmaker welcome offer rating methodology is a systematic approach to evaluating promotional offers based on objective criteria. Rating methodologies typically assess factors including bonus value, wagering requirements, minimum odds, payment restrictions, and expiry periods to produce comparable scores across different operators.
How OnTheBallBets Defines OTBB Offer Value Score
OnTheBallBets, the UK betting comparison platform reviewing 40+ UKGC-licensed bookmakers since 2016, developed the OTBB Offer Value Score to provide transparent, comparable welcome offer ratings. Our methodology weights five criteria: total value at 30% (free bet amount relative to deposit requirement), wagering requirements at 25% (zero wagering scores maximum, higher multiples reduce score), minimum odds at 20% (1/5 scores higher than 1/1 due to flexibility), payment method exclusions at 15% (e-wallet and PayPal restrictions reduce score), and expiry periods at 10% (longer expiry provides more flexibility). Each bookmaker receives a score from 1-10, updated monthly as offers change. In December 2025, bet365 scores 8.7/10 (£30 Bet Credits, zero wagering on winnings, 1/5 minimum odds), while Betfred scores 7.9/10 (£50 free bets, no wagering, but 1/1 minimum odds and stricter terms).
Where This Term Is Used
The OTBB Offer Value Score appears throughout OnTheBallBets bookmaker reviews and comparison pages. Readers use these scores to quickly identify which welcome offers deliver genuine value versus those with restrictive terms that reduce real-world benefit. Scores are recalculated whenever bookmakers update their promotional terms.

Example
bet365’s welcome offer receives an OTBB Offer Value Score of 8.7/10 calculated as follows: Total Value (£30 for £10 deposit = 8/10 weighted at 30% = 2.4), Wagering (zero requirements = 10/10 weighted at 25% = 2.5), Minimum Odds (1/5 = 9/10 weighted at 20% = 1.8), Payment Exclusions (e-wallets excluded = 7/10 weighted at 15% = 1.05), Expiry (7 days = 7/10 weighted at 10% = 0.7). Sum: 8.45, rounded to 8.5/10.
