study the pattern of the game for about a week to understand what that plays most of the time.
You lost me after this sentence... good luck with "studying" lucky-based games for a whole week. I really doubt it will help you (or anyone), but if you think it will give it a go.
The goal is to play safe and not to make you rich, but to increase your chances of winning and minimize your losses and to avoid going bankrupt.
Just deposit the money you can afford to lose, that can really save you from bankruptcy. When you deposit money you can afford to lose try to have fun trying out different strategies, and maybe some of them will work.
Lucky-based games have that name for a reason, and I am sure that any strategy can give some profit at some moment... but for sure the same strategy will disappoint you eventually. Before making a bet I also like to check previous results, and sometimes I hit something nice, many times I lose and I try again... as long as I have balance.
