Will work if you have an infinite supply of wealth. 
is it really worth the try. i'm curious about it and want to try it on freebitco.in. I also found a script online.
For martingale to work two things need to be true:
1) The gambler needs infinite amount of wealth/bankroll
2) The casino/house needs infinite amount of price money
If either of these statements is false, martingale will not be profitable in the long run.
Justdice only has a 1% house edge though, (and recently luck has been 100.05%) so your profitability could be 99% which is much better than most other casinos.
However don't gamble to become rich, as gamlbing will only make you poor. Gamble for fun if you like.
