Welcome bonuses with 30x wagering or less — half the industry average, and the difference between a bonus you can actually clear and one you can't.
You must place qualifying bets worth 30 times the bonus before its value becomes withdrawable — $3,000 in bets on a $100 bonus. Whether the multiplier applies to the bonus alone or to deposit plus bonus makes a huge practical difference, so check that line of the terms first; the second version doubles the real requirement.
Game weighting. Slots usually contribute 100% of each bet to the requirement, while blackjack, roulette, and live tables often count 10% or less — sometimes zero. If you mainly play tables, a 25x slots-weighted bonus can effectively be 250x for you, which is why we read the weighting table before recommending any offer.
Rarely. At typical slot RTP you lose a predictable percentage of every qualifying bet, so total expected loss scales with the requirement, not the bonus size. A $200 bonus at 45x usually costs more to clear than it pays; a smaller bonus at 25x with honest weighting is worth more in practice.
