Cricket Betting Markets
From Bangladesh Tigers to IPL and T20 World Cup — cricket betting is very popular among Bangladeshi players. ctk33 offers a variety of betting markets. See seven common bet types below.
| Bet Type | Explanation | Example |
|---|---|---|
| Match Winner | Bet on which team will win the match | Bangladesh vs India — Bangladesh to win |
| Toss Winner | Which captain will win the toss | Dhaka Dominators to win the toss in a BPL match |
| Top Batsman | Player to score the most runs in a specific innings | Bangladesh's top run scorer in the first innings |
| Total Runs Over/Under | Predict whether the total runs in a set number of overs will be over or under a given line | Whether more than 160 runs will be scored in the first 20 overs |
| Runs in an Over | How many runs will be scored in a specific over | Whether 15+ runs will be scored in the 18th over |
| Method of Dismissal | How the next wicket will fall | Whether the next wicket will be bowled or caught out |
| Player of the Match | Predict who will receive the player of the match award | Which player will be man of the match in an ICC T20 match |
In live in-play betting, odds update automatically after each wicket and at the end of every over. When the run rate increases, the batting team's odds shorten; when a wicket falls, they lengthen.

Crash Games — Fast-Paced Excitement
How do crash games work?
In crash games like Aviator or JetX, each round begins with a plane or rocket taking off. The longer it flies, the higher the multiplier climbs — starting from ×1.5 and sometimes reaching ×100 or more.
You place your bet before the round starts. Then press the cash out button at any time — your bet is multiplied by the multiplier at that moment. But if you do not cash out before the plane crashes, your entire bet is lost.
Using the auto cash out feature, you can set a target in advance (such as ×2.0) — when the multiplier reaches that level, it will cash out automatically.
Warning: Crash games are fast-paced and exciting, but outcomes are entirely random. Always set a stop-limit before playing and stay within a fixed budget. Do not trust any "prediction signals" or "secret strategies".
RTP and House Edge Explained
RTP (Return to Player) is a theoretical percentage that gives an estimate of how much a game will return to players over the long term. For example, if a slot's RTP is 96%, there is an average chance of ৳96 coming back for every ৳100 bet — however, this is a long-term mathematical average, not a guarantee for any single session.
House edge is the flip side of RTP — the percentage the game retains in the casino's favor over time. If the RTP is 96%, the house edge is 4%. RTP varies across different game categories: slots generally fall between 92-98%, blackjack with correct strategy is around 99%, and roulette can typically range from 94-97% — these are general industry ranges; check the game provider's information for specific game values.
Volatility or variance is another important concept. In high-volatility games, big wins come less often but many short sessions can result in losses. In low-volatility games, smaller wins come more frequently. Choose the right game according to your budget and playing style.
Understanding RTP and house edge is important because it helps you make informed decisions. Remember, casino games are for entertainment — over the long term, the math of every game favors the casino. Play responsibly and do not bet more than you can afford to lose.
Typical RTP Ranges (Industry Averages)
| Game Type | Approximate RTP Range |
|---|---|
| Slot Games | 92% – 98% |
| Blackjack (with correct strategy) | ~99% |
| Roulette (European) | 97.3% |
| Baccarat | 98.7% – 98.9% |
| Crash Game (Aviator) | Variable |
How to Read Odds
Decimal Odds
The most commonly used format on ctk33. Simply multiply the odds number by your bet amount to get the total return.
Example:
You bet ৳500 at odds of 1.80
Total return = ৳500 × 1.80 = ৳900
Profit = ৳900 − ৳500 = ৳400
Implied Probability
Odds make it easy to understand how likely a bookmaker thinks a particular outcome is.
Formula:
Probability (%) = 1 ÷ Decimal Odds × 100
Odds 1.80 → 1÷1.80×100 = 55.6%
Fractional and American
A quick comparative reference for other formats:
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳100 → ৳180 |
| Fractional | 4/5 | ৳100 → ৳180 |
| American | −125 | ৳100 profit on a ৳125 bet |
