Sports Betting
Cricket Betting Markets
b3777 offers a variety of markets for cricket betting. Before placing a bet on BPL, IPL, T20 World Cup or other matches, take time to understand the markets.
| Market Name | Description | Example |
|---|---|---|
| Match Winner | Bet on which team will win the match. | Bangladesh vs India — pick Bangladesh as the winner. |
| Toss Winner | Predict which team will win the toss at the start of the match. | Bet on the toss market and find out the result quickly. |
| Top Batsman | Which batsman will score the most runs in a given innings. | Pick the highest run-scorer in the first innings. |
| Total Runs Over/Under | Whether the total runs in the full match or a specific innings will be above or below a set number. | Choose whether runs in the first innings will go over or under 160. |
| Runs in a Session/Over | How many total runs will be scored in an over or during the powerplay. | Bet on 50+ runs in the first powerplay. |
| Method of Dismissal | How the next wicket will fall — bowled, caught, run out, etc. | Bet that the next wicket will be a catch out. |
| Player of the Match | Which player will be named Player of the Match at the end of the game. | Pick any bowler or batsman as Player of the Match. |
How Does Live In-Play Betting Work?
Odds shift quickly when a wicket falls or a big over is bowled during a match. When a key batsman gets out, the defending team's odds shorten; conversely, when runs flow in the powerplay, the batting team's odds improve. Live betting creates opportunities from these shifts — but analyze the match situation carefully before placing a bet.
