I will talk about online casinos . I played casino games on the website paidverts and convinced myself that the slogan "The house always wins" is very true. I used to play a bit in roulette with a 90% chance of win combination and still lost .
Online casino games like roulette, blackjack, slot machines etc are especially made so the house will always win.
Do not waste money on casino games ,if you still want to waste some money online, join to a new hyip , it same risk but you will have a higher chance to get some money back than winning big amounts in the beginning then later lose everything.
Online casinos games are in fact computer programs (robots) which are created to execute code lines to make you win the beginning and to make you to keep gamble . In the end you will lose all your money. Even if today you win, tomorrow you will lose .
Keep in mind, there is no luck in online casino games only program code lines made by a programmer and sold for profit.
If online casino games would have real chances of luck, many casino websites would go bankrupt .
And don't trust those hash proofs of luck (Provably fair) you will see that you will lose everything.
