Popular Cricket Betting Markets
These are the most played markets in cricket betting. A good understanding of each market makes it much easier to make decisions.
Match Winner
Bet on which team will win the match. Example: Bangladesh vs India — if Bangladesh wins, your bet could double.
Toss Winner
Which team will win the toss at the start of the match. Simple and quick result. Example: Bangladesh will win the toss in a T20 match.
Top Run Scorer
Predict which batter will score the most runs. Example: the top batter for the Tigers in this match.
Total Runs Over/Under
Whether the total runs in a full innings will be above a set number. Example: total runs in 20 overs will be above 160.
Wicket Type
How the next wicket will fall — bowled, caught, run-out, or LBW. Example: the next wicket will be caught out.
Player of the Match
Who will be named Man of the Match at the end of the game. Example: an all-rounder from the Bangladesh team as top player.
Live In-Play Odds
In live betting, odds change after every wicket and at the end of every over. When a team's run rate rises, the favourite's odds shorten; when a wicket falls, the opposing team's odds move up quickly. Watching live statistics and placing a bet at the right moment is the strategy of a skilled bettor.
Types of Slot Games
555nn offers several types of slot games. Each has its own features — find out which one suits you.
Classic Slots
Simple games with 3 reels and a limited number of paylines — gives the feel of a traditional slot machine. NetEnt's classic series is a good example.
Video Slots
Modern 5-reel slots with various themes, animations, and bonus rounds. Pragmatic Play's Gates of Olympus and Sweet Bonanza are of this type.
Jackpot Slots
A large progressive prize pool that one player can win all at once. Microgaming's progressive jackpot series is notable.
Megaways Slots
A different number of symbols appears on each spin, creating thousands of ways to win. Big Time Gaming invented this mechanic.
Cascading Reels
Winning symbols disappear and new ones drop down — giving you a chance to win multiple times on a single spin. Pragmatic Play's Sugar Rush is of this style.
Cluster Pays
A cluster of adjacent matching symbols pays out — rewards are based on count rather than lines. NetEnt and Push Gaming make games of this type.
Familiar Card Games in a New Form
Card games you have known since childhood are now available to play online — with a live dealer or against other players.
Teen Patti
Each player is dealt 3 cards and the one with the highest hand wins. You can choose to play blind or look at your cards while placing bets. Starting tip: begin with small bets and wait for a strong hand. This is played against other players through a live dealer.
Andar Bahar
One card is placed face up in the middle, then the dealer deals cards alternately to two sides. If a matching card comes on the side you chose (Andar or Bahar), you win. Starting tip: since it is an even-chance bet, this is ideal for beginners. Played against a live dealer.
Callbreak
A trick-taking game for 4 players where you must predict how many tricks you will win before each round. Spades (♠) are always trump. Starting tip: if you have at least 3 spades, you can be confident. This is played against other players.
Ludo / Rummy
In Ludo, roll the dice to bring your pieces home; in Rummy, arrange sets and runs to finish your hand first. Both are strategy games where skill matters alongside luck. Both are played against other players.
How to Read Odds
In betting, odds are the numerical expression of the probability of winning. There are three main formats — decimal, fractional, and American. The most widely used format in Bangladesh is decimal.
Decimal Odds Example
You placed a bet of ৳500 at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900
Net profit = ৳900 − ৳500 = ৳400
Implied Probability
To find the probability of winning from decimal odds: 1 ÷ odds × 100. At odds of 1.80: 1 ÷ 1.80 × 100 ≈ 56%. This means the bookmaker considers the probability of this outcome to be around 56%.
Format Comparison
| Format | Example | Explanation |
|---|---|---|
| Decimal | 1.80 | Total return = stake × odds |
| Fractional | 4/5 | Profit = stake × (4÷5) |
| American | -125 | Need ৳125 to win ৳100 |
RTP and House Edge Explained
RTP means Return to Player — the percentage of total bets a game pays back over the long term. For example, a slot game with 96% RTP returns an average of ৳96 for every ৳100 wagered — but this is a mathematical average across billions of spins, not a guarantee for any single session.
RTP ranges vary across different game types. Slots generally fall between 92% and 98%, blackjack can approach nearly 99% with the right strategy, and roulette typically sits between 94% and 97%. Live casino games generally have a comparatively higher RTP.
House edge is the flip side of RTP — the percentage the casino retains on average from each game. If RTP is 96%, the house edge is 4%. This margin is the foundation of a sustainable business for operators.
Knowing a game's RTP before you play helps you manage your budget better. A higher RTP means more opportunity to play longer — but not a guarantee of winning. Play responsibly and stay within your limits.
