Metadice (http://metadice.com) is a Litecoin dice game that has been running successfully for six months now, and it's attracted a fair amount of interest from very little advertising (mostly through Bitvisitor and also listed on Bitcointalk).

• 3,500 unique visitors (according to Google Analytics)
• 2:46 average stay
• 2,704 bets totalling 7565 LTC
• 492k transaction processing batches, 219k payment batches
• Provably fair betting algorithm, no need to sign up
• Support for blacklisting addresses to combat problem gambling
• Since it always provides a tx fee, blockchain bloat isn't a problem - 93.35 LTC has been paid to miners

From an initial investment of 60 LTC, the site balance has at times been as high as 262 BTC and has been enough to cover hosting costs, development costs etc. However the site's run out of LTC to bankroll, and we're not interested in continuing the site, so we're looking at selling it. We've already implemented all of the hard work with dealing with multi-bet transactions, unusual senders, invalid bets, too low/too high etc.

Technical features:

• Implemented using PHP/MySQL and served over Apache
• Fully automated and configurable, e.g. min_confirmations, min_balance, max_payment, min_bet, max_bet, house_edge, transaction_fee, loss_payment...
• Uses OpenID for administrator authentication
• Bet transactions occur independently from the website, and can run on separate servers - if the site is DDOSed, transactions will continue to process
• Designed to work with ANY BTC-based cryptocurrency: expansion plans included supporting betting in BTC, LTC, NMC, FTC
• Currently running on a 1GB VPS in Amsterdam (expires in 3 days)
• Various anti-spam and anti-DDOS protections in place
• Automated database backups

Any serious offers considered. We can also help with hosting, management, configuration and development of the site if necessary if you just want to provide a bankroll, or you can purchase the source code with a limited amount of deployment support, or anything inbetween. You will however have to deal with any legal/regulatory issues in your country of residence/operation if applicable. Send us a PM.

When I was first starting out with BTC I found Bitvisitor was a good way to slowly accumulate BTC (not to mention spam my wallet with transactions that were barely enough to cover tx fees ) so, with my new site Metadice (http://metadice.com), I was wondering how effective it would be as a marketing tool... I thought I'd share the results of my experiment.

Firstly the processing step was pretty quick. It seemed to rely on zero-confirmations, and cost me 0.031 BTC for 1000 visitors (I spent 0.062 BTC for 2000 visitors).

Secondly, I found out the hard way that my site was not yet optimised enough for that many visitors some quick terrifying Google and IRC searching later, I had tweaked Apache2's settings correctly, and put learning Nginx on my todo list.

These are the results from Google Analytics:

• Visits: 637; 564 unique (less than the 2000 expected)
• Page views: 1,176
• Average visit duration: 1:50 (Bitvisitor requires you to stay on the page for 60 seconds)
• Pages per visit: 1.85 (not many visitors click past the first page)
• Returning visitors: 11.3%
• Countries: US 23.8%, Spain 9.4%, Germany 8.8%, UK 5.8%, Italy 4.6%, Netherlands 3.6%, Canada 3%, New Zealand 3%, Russia 2.7%. I'm sure this is also dependent on the time that I requested the advertising, it was EU daytime.
• Browser: Chrome 50%, Firefox 40%, Opera 4% (IE 1.4% thank goodness)
• Mobile browser: Android 72.4%, iOS 27.6%
• Bets placed: ~5

So I think Bitvisitor is a good way to get a bunch of traffic, although it probably matches BTC demographics closely, most users will just ignore the page content, and very few will actually interact.

[Features:]

I noticed that there seemed to be a lack of Litecoin dice sites, http://ltcdice.net/ seems to have disappeared and many of the others look boring, so over the last two days I've put together a dice site that tries to be a little bit smarter in the way it operates.

http://metadice.com



Features:

•     Fully automated betting with 98%+ break-even odds.
•     Faster to verify than BTC betting since LTC transactions are naturally processed faster!
•     Provably fair betting algorithm (of course), no need to sign up - but you must send LTC from a wallet that lets you receive coins on the same address (default client works great).
•     Improve your winnings and reduce blockchain spam by using non-confirming addresses - instead of receiving 0.001 LTC on a loss, non-confirmation improves your winnings by 0.2%.
•     Accessible over Namecoin DNS, http://metadice.bit - e.g. through dot-bit.
•     Combat problem gambling by blacklisting addresses - I was inspired by patrikr's comment on Reddit, if you find you have a problem you can force the system to ignore your bets.

The most interesting learning experience has been just how much the default Litecoin client tries to avoid blockchain spam. Any payment smaller than 0.0001 LTC is ignored by the client, and for anything but large transactions the client requests a 0.02 LTC transaction fee. Therefore you'll probably have most luck with bets above 0.02 LTC.

The site is kinda still in beta but if you have any feedback or ideas I'd love to improve the game. The site only has a limited wallet so maximum bets are low for a while. Feel free to PM me! I have a lot of other ideas that I'd like to implement e.g. accessible over Tor?
