What you should know before betting
Habits that experienced players follow — they are just as useful for newcomers.
Set a weekly budget
Allocate a fixed amount each week and place only a small, set portion of that budget on each bet. Putting your entire budget on a single bet is not a good idea.
Understand decimal odds
Decimal odds of 2.25 mean you get back a total of ৳2.25 for every ৳1 bet — that is a profit of ৳1.25. The higher the odds, the lower the probability but the greater the potential return.
Be careful with multi bets
A multi bet returns much more if all selections win, but if one selection loses, you lose the entire bet. Multi bets are popular in cricket and football but carry higher risk.
Research before the match
Before betting on BPL, IPL or international cricket, check the team's recent form, pitch conditions, weather and team news.
Do not bet on emotion
Placing a large bet to recover a loss is a common mistake. If you lose, take a break — trying to recover losses increases the risk of losing even more.
Keep a record of every bet
Note down each bet to understand which games or market types are resulting in more losses. This helps with decision-making over the long term.
Set time limits
Use deposit limits and session time-outs. These tools are available at 5666 bet and help you stay in control of your play.
Remember: Betting is for entertainment, not a source of income. For those aged 21+ only.
