Many casinos operate a policy whereby after you have finished spinning the reels using your no deposit spins you need to make a deposit in order to start tackling the attached wagering requirement, but at Royal Panda a similar policy applies at all times - only spins paid for using your cash balance reduce your active wagering requirement. As a result, if your cash balance becomes fully depleted then the best course of action is to stop playing until you are ready to deposit again as this way the bonus funds will stay on record until such time as you have finished the required wagering and the money is added to your real cash balance. If you use this technique you can be certain that eventually you will receive the bonus money in full, however there are some players who don't like this as it potentially plays into the hands of problem gamblers who might be tempted to carry on depositing money they may not be able to afford in the hope of being able to keep on playing long enough to withdraw the bonus money.
Apart from this rule this is a very straightforward and fair bonus with a lower than average (at least for by current industry standards) wagering requirement of 35x the bonus amount only. Almost all casino games are permitted for pay however table games such as Blackjack and Roulette, plus Video Poker and Live Casino have a reduced contribution percentage of 10%. I think this is fair considering these lower contributing games are often not permitted at all. I was pleased to find that my favourite NetEnt game Dead or Alive is allowed as well albeit with a reduced maximum bet size of £1.
Personally I feel happy with the bonus system at Royal Panda and have begun to play there quite frequently this year - they have a weekly reload bonus available as well which follows the same rules which is a great incentive to keep on playing here.
