a few years back, there used to be an online poker site called "Empirepoker". Looked to me somewhat related to Partypoker or some other site, so it must have been an affiliate site. It was all back in the years when bonus hunting and freeroll tournaments was a very interesting business modell to many players and a way to supplement income.
However, they had a loyality program which reminds me somewhat of Boyd's program. It worked in a way that you could earn daily loyality points by playing (played hands, e.g. dollars wagered). So, for every dollar you played, you used to get 1 point...at the beginning...but then it changed and they started giving you points based on the square root of your hands played . So....100 hands played....10 points.... 400 hands played...20 points, ....2500 hands played....50 points. and no unlimited number of points earned daily in order to achieve the top tier level. In fact, it was irrelevant, because at some level it makes no more sense to earn additional points because it takes too much play... 10,000 daily points = 100 loyality points (square root)...but in order to earn 200 loyality points, it would have required 40,000 daily points, which of course is a hell of a play and is basically impossible to accomplish.
So people figured out this system and just played long enough until it was not worth the time anymore playing longer sessions and then they would switch back to partypoker (which had the same players on it connected). When you had your 100,000 points together, they would send you a nice "Empire Poker" watch and you were eligible for other benefits, such as bonusses, free play, tournaments, etc. It was good but the concept failed because heavy play was only honored to a certain degree.
Boyd's concept reminds me a little bit of it, as they want the players to play slots and perhaps table games but the heavy videopoker players, although they bring in a lot of money, are being pushed away because management believes they are not interesting enough to the earnings percentage. Well, probably this way of seing things will get some adjustments in the next couple of years.....
