Actually he won 0.5 ETH, but I'm not saying it to diminish his success. Winning $70 while risking, what, $0.00062, is amazing. I didn't know such multiplier even existed!
I just realized that although he was starting low, he could cash out a decent amount before opening the 8th tile. I'm not sure, but I think it could be something above $20. And this guy had the balls for opening the next tile!
actually there is even more biggest multiplier which is 5148300.00 x and you can see it on the stake forum here:

Wow! Thank you very much for this link! The OP was created by Faris, a long time friend of mine through PrimeDice chat. I think his win was even more amazing than the one you quoted here, because he won 0.1765 BTC with just 4 sats as initial bet.
So, this is it? You should play on a field with 13 mines and successfully open 12 tiles (or, alternatively, successfully open 13 tiles on a field with 12 mines) to get the 5,148,300x multiplier? I think it is, and I also think that this is a valuable information few people are aware of.
