Wagering requirements are the hidden trap in many welcome bonuses. A 35x requirement means wagering 3,500 DKK to withdraw a 100 DKK bonus. No-wagering casinos - or those with very low requirements - deliver more real value, even when the headline bonus looks smaller.
PlayOJO is the best-known example in Denmark: winnings from free spins are often credited without classic wagering. Always read current terms - «no wagering» may apply to spins but not match bonuses.
Also check max. withdrawal and game restrictions. A fair no-wagering bonus with a low max. win can still be less attractive than a larger offer with transparent 10x requirements.
