I've lost about 0.02BTC within 10 secs on minesweeper on my first bet 
But if you won on that bet, you will be earning a lot
I'd suggest playing with dice games or poker - you got better chances of winning than minesweeper. Well, this is based on my experienced and not entirely true to all - there are just very lucky people that are killing it.
That .02 can have many playing time with dice games and it is also fun chatting with other players in the chatroom
Better chances? No way. Same chances everywhere: 50/50. You can loose on dice betting with 97% chance too, first bet. It happened to me a lot of times. Just luck, guys... just luck, that's what gambling is about. You can win with 0.01% chance first bet, or you can loose first bet with 99.99% chance.
Haha yeah it is true it's just win or lose, so it's 50/50 others create another one but of course to their own advantage. Choices are win lose or draw, if number is draw you lose when you chose either of the two other option and same goes.
Anyway, chasing lose and losing it again and again make everyone cry i think
