I noticed in the details shown to the right on this page that the wagering requirement for this offer is listed at 30x the deposit plus bonus but I was reasonably sure it was lower than this when I signed up. I checked the current terms and conditions on the Bet365 website and can confirm that at present the actual wagering requirement for this bonus is 20x the deposit plus bonus, or 30x the bonus amount effectively. That's really as low as you will find anywhere at the moment and 200% deals are becoming rarer and rarer all the time, so I definitely recommend giving this bonus a try whilst it is still available!
The bonus comes with few restrictions by current standards and all types of game apart from a few very low house edge table games are allowed for wagering purposes including Video Poker (contribution percentage 5%) and most roulette and blackjacks (contribution percentage 10%). It's easy to check your progress with the wagering requirement from the My Account page which is accessible directly from within the Playtech games or from the main Bet365 Casino page otherwise.
