Cricket Format Guide
It is important to know the different formats before placing cricket bets. Betting markets vary by format.
T20
20 overs per innings, match duration around 3 hours. Bets on sixes, wickets, and Man of the Match are popular in this fast-paced format. BPL and IPL are played in this format.
ODI (One-Day)
50 overs per innings, match duration around 8 hours. The ICC Cricket World Cup and most Bangladesh Tigers series are played in ODI format. Mid-innings betting is quite popular.
Test
Up to 5 days of cricket with two innings per team. Match results can often be unpredictable, making session-by-session betting markets quite interesting.
The Hundred
A new format introduced in England where each innings consists of 100 balls. The betting markets in this fast-paced format are similar to T20 but dramatic shifts happen in even less time.
Popular Leagues: BPL (Bangladesh Premier League), IPL (Indian Premier League), BBL (Big Bash League), PSL (Pakistan Super League)

Types of Slot Games
The world of slot games is highly varied. Learn about the different types of slots.
Classic Slots
Traditional 3-reel slots with simple gameplay. Many classic NetEnt titles fall into this category.
Video Slots
Modern 5-reel slots with bonus features and animations. Pragmatic Play and PG Soft produce this type of game.
Jackpot Slots
Slots with progressive jackpots where the prize keeps growing. Microgaming is well known in this category.
Megaways Slots
The number of ways to win changes with every spin, offering thousands of possible winning combinations.
Cascading Reels
Winning symbols are removed and new symbols fall from above, making it possible to win multiple times in a single spin.
Cluster Pays
A win occurs when a cluster of matching symbols forms on a grid. Some popular NetEnt games use this mechanic.
Fishing & Arcade Games
Fishing games are very popular among players in Bangladesh. In these games, you use a cannon to catch various fish and earn rewards based on each fish's multiplier.
How does it work?
Increasing the cannon level raises the cost per shot but also increases the chance of catching bigger fish. Smaller fish have lower multipliers but are easier to catch. Taking down a boss fish can earn you bigger rewards.
Classic Fishing
A standard fishing game, ideal for beginners. JILI's Mega Fishing and Jackpot Fishing are popular choices.
Bombing Fishing
Use explosives to take down many fish at once. Higher risk, higher rewards.
Boss Fish Challenge
Special boss characters appear, and taking them down earns you massive rewards.
Shot Cost Tips
Set your cannon level according to your budget — rather than starting at the highest level, increase it gradually.
RTP and House Edge Explained
RTP, or Return to Player, is the long-term calculated return rate of a game. For example, if a slot has an RTP of 96%, it means that on average ৳96 is returned for every ৳100 wagered. However, this is only a mathematical average — in any single session you may receive much more or much less.
House edge is the flip side of RTP. If the RTP is 96%, the house edge is 4%. This 4% represents the casino's long-term calculated profit. This figure varies across different types of games.
| Game Type | Typical RTP Range | House Edge |
|---|---|---|
| Slots | 92% – 98% | 2% – 8% |
| Blackjack | Around 99% | Around 1% |
| Roulette (European) | 94% – 97% | 2.7% |
| Baccarat | Around 98.9% | 1.1% |
A higher RTP is not always better — volatility matters too. High-volatility games can deliver big wins but you may go longer stretches without winning. Low-volatility games pay out smaller wins more regularly. It is wise to choose a game based on your budget and playing style.
How to Read Odds
Decimal Odds
Decimal odds are the most commonly used format on betting sites in Bangladesh. They are very straightforward — simply multiply your stake by the odds to get your total return.
Example: You place a ৳500 bet 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, divide 1 by the odds and multiply by 100.
Example: 1.80 odds → (1 ÷ 1.80) × 100 = approximately 55.6%
| Decimal | Fractional | American (Moneyline) |
|---|---|---|
| 1.50 | 1/2 | -200 |
| 2.00 | 1/1 (Evens) | +100 |
| 2.50 | 3/2 | +150 |
| 3.00 | 2/1 | +200 |
Quick Reference
Decimal Odds — the simplest format. Shows total return directly. Common in Europe and Asia.
Fractional Odds — British style. 3/1 means ৳3 profit on a ৳1 bet.
American Odds — positive (+) shows potential profit on a ৳100 bet; negative (–) shows how much you need to bet to win ৳100.
On zb66, all odds are displayed in decimal format — the most convenient option for bettors in Bangladesh.
Bankroll Management Guide
Learning bankroll management is essential if you want to bet responsibly. It is not just a strategy to avoid losses — it is a way to keep the enjoyment of playing alive over the long term.
Setting a Gambling Budget
Only use money that, if lost, will not affect your household or daily life. Set it aside as an entertainment budget.
Session Splitting
Divide your monthly budget across 4 to 5 sessions. This way there is no risk of going through your entire budget in a single day.
The 1–5% Betting Rule
Never place more than 1% to 5% of your total bankroll on a single bet. This is the most effective rule for the long term.
Take a Break After a Win
After a big win, set aside a fixed amount and continue playing with the rest. Giving back all your winnings is a common mistake.
Stop After a Loss
If you lose 50% of your session budget, stop playing. Trying to chase losses risks losing even more.
Keep a Record
Write down your deposits, withdrawals, and results for every session. This will help you understand your patterns and make better decisions in the future.
