Cricket Betting Markets
Cricket betting at b3666 is not just about the match winner — there are dozens of markets available. Learn about the most popular bet types below.
Match Winner
Bet on which team will win the match. Example: Bangladesh vs India — pick either side.
Toss Winner
Predict which team will win the toss before the match starts and place your bet. Popular for short-term, quick-result betting.
Top Batsman
Bet on which player will score the most runs in a specific innings — within one team. Understanding the batting line-up helps in this market.
Total Runs Over/Under
Bet on whether the total runs scored in a full innings or a specific powerplay will be above or below a set number.
Runs in an Over/Session
Bet on how many runs will be scored in a specific over or session. This is particularly exciting for in-play betting.
Method of Dismissal
Bet on how the next wicket will fall — bowled, caught, run out, LBW. A deeper knowledge of cricket comes in handy here.
Player of the Match
Bet before the match on who will be named Player of the Match at the end — a batsman or a bowler.
In-Play Betting: How Live Odds Move
When a wicket falls during a match, the batting team's run rate drops and the odds shift quickly in favour of the bowling team. A high-scoring over pushes the batting team ahead, and their odds in the match winner market shorten as a result. In the final overs, odds are updated after every ball based on the run target and wickets remaining. Making fast decisions and keeping a clear head are the most important skills in live betting.

Live Betting & Cash Out
In-play betting means the chance to place bets while a match is in progress — the situation changes with every wicket and over, and so do the odds.
What is in-play betting?
In-play betting is the opportunity to place bets even after a match has started. In cricket, odds update after every ball; in football, after every goal. This gives you the chance to make decisions based on how the match is unfolding.
What is cash out and when should you use it?
The cash out feature lets you withdraw part or all of your bet before the match ends. When your preferred team is ahead but the match seems uncertain, cashing out can be a smart decision.
4 tips for staying calm in live markets
When a big wicket falls or a lot of runs are scored in an over, odds change quickly — don't rush, wait a few seconds and make your decision once the odds stabilise.
Decide in advance the maximum amount you will bet on a single match — it's easy to go beyond your budget in the excitement of live betting.
Avoid the urge to place a larger bet to recover a loss from a previous bet — this usually makes the situation more complicated.
Cash out is a tool, not an obligation — you don't always have to use it. Analyse the situation and then decide.
Bankroll Management Guide
Responsible gaming isn't just about following rules — it's a way to keep your entertainment enjoyable over the long term. Follow the guidelines below.
Set a Budget
Decide in advance the maximum amount you will spend on gaming each week or month. This amount should be something that, even if lost, will not affect your daily life.
Divide into sessions
Split your weekly budget across several sessions. Instead of spending your entire budget in one session, play in smaller portions — this way you can enjoy more time.
The 1–5% rule per bet
It is wise not to place more than 1% to 5% of your total bankroll on a single bet. Following this rule means one bad result cannot wipe out your entire budget.
Stop after winning
After a good winning streak, take a break once you have reached your target. The tendency to keep going after a win is often the cause of bigger losses.
Stop after losing
Set a "stop-loss limit" in advance. Once you reach that limit, end the session — coming back the next day with a fresh mind is always better.
Keep a record of your play
Note down how much you have deposited, how much you have withdrawn, and what the net result is. This helps you see the real picture and manage your habits.
Gaming should be for entertainment — not as a source of income. If you feel there is a problem, read the responsible gaming page.
