Bonus
I don't expect the 10% continuing bonus model, other casinos do this. I get the impression casinoshare are trying to do things other casinos don't.
Offers mailed to players (my vote), although done at a few other groups, will enable them to target the offers to the players. Players they don't want will get less, and players they believe are going to be loyal, and above all profitable, will be given offers to encourage them to deposit regular amounts.
I would expect them to run open competitions.
Above all though, sort out the loyalty programme - this has been long promised but seems no closer, secondly, BEFORE embarking on new promotions they need to get their support up to speed, as any changes are going to produce an increased demand.
I would recommend bonuses to be automated as they have the EZBonus system, and players are not tied in to obscure restrictions just because a bonus has been added. An alternative would be to have claim codes and a claim page, E-mailing support does not seem too effective at present.
They have another promotion at present, $500 for wagering $40,000 on some slots by the 23rd, but no loyalty scheme in place, and claims have to be E-mailed, and the previous promotion didn't seem to work properly. With no loyalty scheme, it is hard to determine how much has been wagered.
Telling players they can use Playcheck is complete BS, it does NOT show wagering totals, it only shows individual games and results. Casinos have an extension that allows the tally of a players total wagering from the Playcheck data, but this is unavailable to players.
