Headline figures like “200% up to £1,000” grab attention but say little about real value. Wagering rules, game weighting, time limits, and cashout caps matter more.
Why big numbers mislead
A £200 match with 20× wagering and no cap may offer better practical value than a £1,500 offer with 60× playthrough and a £100 max withdrawal — even though the second looks bigger on the banner.
Check wagering first
35× on a £50 bonus means £1,750 in qualifying bets. Under 25× is player-friendly; above 40× is tough. See whether the multiplier applies to the bonus only or bonus plus deposit.
Game weighting and time limits
Slots usually count 100%; tables may count 10–20%. Short expiry windows (7 days) make large bonuses harder to clear than longer ones (30 days).
