The name itself is okay, although the word "incentives" is geared to attract the less lucrative "freebie hunters" rather than the more serious gamblers which is a shame - so IMO if it were undeveloped then maybe high $xx.
The fact you have developed it and got some SEO going though makes it way way more attractive to an end user. You have traffic and revenue, so any sale would be based more on those factors.
If you ever come to sell, PM me some rev stats to mull over.
