there's an idea to start a bitcoin charity on indiegogo that needs some backers, it looks like an interesting idea.

it's a fun time waster but I think it's a scam frankly.  the hi/lo game claims you 'win' if you hit "hi" above 5250, however I've had numbers rolled higher than 5250 that don't pay so i think it's either a scam or their program has a major bug and they don't care because it benefits them.  though i don't know how since it's a free game anyway!
