Hello everyone,
i made a Bitcoin based game called Hop or Flop:
http://www.hoporflop.com/The rules are:
Bet some BTC by sending them to a specific address.
After some time for confirmation the game starts and at a 50 % chance Hop or Flop sends you double back (except the 0.0005 Btc fee, if the win is higher than that).
So its pretty simple, its either Hop (bet gets doubled) or Flop (nothing).
Have fun and luck
