Big bonuses grab attention, but the headline figure is only half the story. A “$10,000 welcome” or “360% match” is only as good as its wagering requirement, max bet and game weighting. Below are the casinos with the largest deposit-match and free-spin offers we’ve tested — and we tell you the catch on each. Prefer no-strings rewards? See our no-KYC and rakeback-focused picks instead.

How to judge a big bonus
Multiply the bonus amount by the wagering multiple to get the total you must bet, then weigh that against the house edge of the eligible games. If clearing it costs more than the bonus is worth, skip it. Our crypto bonuses guide has a 30-second value check, and the full bonuses comparison lists every offer side by side.
