- Always play only for fun. Bet only what you can afford to lose.
- Be prepared to walk away! Set yourself time limits for how long you will play for and do not add extra time or money to that upper limit.
- Do not deposit anything, before your account is fully verified. Because any bookie will accept your bet without verifying your account, but if you win and request a withdrawal, they will refuse and ask you for verification. You might not pass it for a lot of reasons, like betters from your country are not allowed to use that bookie, or the documents provided by you are not acceptable e.t.c...
- Do not bet a big amount of money, because if you will win, bookie will use all tricks to not pay you big amount of winning. Most common reasons you will hear are multi accounting, fraudulent activity, incorrect bets, e.t.c.. They will simply block your account and confiscate all your money. In some cases bookie might return only your bet amount and refuse to pay winnings.
- Do not be fooled by some kinds of "Super Promotions" like "Place multi bet that will include not less that 4 positions with minimal odd 1.4 and if only one position loose we will return you the half amount of the bet" Multiply bets gives a big advantage to bookmaker because the possibility of win in case of 4 multi bets is equal to 20% or even less. Also avoid any kind of bonuses, because if you will accept them, you will find out that 4 rollovers bets are required to get 100% of offered bonus. Any promotion or bonuses offered by bookmakers are nothing but a way to force you loose more of your money.
- Avoid playing slots, because all slot games are pre-programmed to 80/20% in the bookies favor.
- Avoid to accept so called casino bonuses that are offered by bookmakers, that have integrated casinos, in addition to sports betting. Because, some of them can actually confiscate any money you try to withdraw before you will satisfy the bonus “terms and conditions”
- Sometimes you may see that all poker tables are busy or a lot of players are online playing different games. Don't be fooled. A lot of bookies are using pre-programmed bots to create a fake buzz and make you believe that a lot of gamblers are betting big amount of money and their platform is very popular.
THIS TIPS DO NOT MEAN THAT ALL BOOKMAKERS ARE SCAMMERS AND ARE PUBLISHED FOR INFORMATIONAL PURPOSES ONLY.
My only addition to your list would be to shift seven up to first place and add a new second rule:
Be prepared to walk away! Set yourself time limits for how long you will play for and do not add extra time or money to that upper limit.
