not for the next six months or so. I'm focusing my development time right now on the more wild ideas I've been coming up with lately, in hopes that one's a hit that the big casinos will want to license from us. We've already been in talks with a few major software providers about Mayan Gold and this new one, so I think I'm on the right track. I'm also spending time on a new site (soon to be announced) that I think will give a nice lift to Bitcoin as a whole.
Having said that, though... our "jack of all trades" NSlots game can be played as a 5-reel slot, with 3 pay lines and adjustable weighting on the reels (for adjustable volatility -- it always comes in between about 90% and 98% RTP). The blue bar icons at the top of the game let you change the number of reels. And of course, Sixty Watt Slots is 5 reels and can be played for 5 credits, which gives three straight lines and two "V" lines.
The only drawback to developing new standard slots is, there isn't much of a secondary market for them these days. And we're trying to differentiate ourselves by breaking new ground. Here are a few screenshots of NSlots doing its 5-reel thing:
