Casino on Net (aka 888.com), established in 1997, is one of the longest running and most respected online casinos in the world. They offer a 100% bonus on deposits of up to $200, and require a modest 20xB worth of wagering before you may withdraw.
First up, let me say that I enjoyed being able to play through this one on my iMac. Generally most casinos require a windows installer, or their flash software requires Microsoft's Internet Explorer. This illustrates the little extra air of polish about Casino on Net compared to most others - in fact I'd go so far as to say it is one of the most impressive online casinos I have come across.
So I went about my regular three hands of $5 multi-hand blackjack and had a pretty average session. Never really going much above my starting balance of $400, I completed the wagering requirements with only $165 in the bank. I tried a few of 888.com's other games including video poker and red dog and lost a little more when I decided enough was enough for this session. Final balance $138.
