What are casino bonus wagering requirements?

Wagering requirements are simply the amount of times you need to wager the bonus funds at the casino before those funds become eligible for withdrawal.  For example, a 35x wagering requirement on a bonus of £100 will require you to wager that money 35 times.  In other words, if you’re playing slots, that would be £3,500 worth of spins.  Often this is more achievable than it seems if you play sensibly with low variance games.
