I've created a poor man's bitcoinduit round... .1btc minimum, the jackpot is up to 2.3 at the time of this writing! Just in case someone wants to use some of their freshly minted coins to try to win more! Bitcoinduit is fun, so even if you don't' like my round, there's others on the bicoinduit site in case you're a higher roller than I!

There's a help/rules link on bitcoinduit as well to explain how the game works. Think simplified ponzi with a jackpot.
