Cricket Format Guide
In Bangladesh, cricket is more than a sport — it is passion. ck1771 offers betting on every cricket format. Understanding each format makes it easier to make informed betting decisions.
T20
Each team bats for 20 overs. A match typically ends in 3 to 3.5 hours. Ball-by-ball betting, toss markets and top batter markets are popular in this fast-paced format. IPL, BPL and the T20 World Cup are the main tournaments in this format.
One-Day (ODI)
Each team plays 50 overs. A match usually finishes within 8 hours. Match winner, top run-scorer and century markets are most common in ODIs. The ICC World Cup is the premier event in this format.
Test
The longest format, played over 5 days with each team batting twice. Series winner, draw markets and fifth-day result betting are available. Bangladesh Tigers are steadily improving in Test cricket.
The Hundred and Other Leagues
In The Hundred, each team faces 100 balls — the fastest format of all. ck1771 also offers betting on leagues such as BPL, IPL, BBL and PSL.
Top Game Provider Studios

Types of Slot Games
Online slots come in various types. Each has its own mechanics and ways to win. Picking the right type makes the experience more enjoyable.
🎰 Classic Slots
Traditional 3-reel slots with simple rules and fewer features. An ideal starting point for new players. Microgaming is well known in this category.
🎬 Video Slots
Modern 5-reel slots featuring animations, bonus rounds and free spins. Pragmatic Play is particularly well known in this category.
💰 Jackpot Slots
A portion of every bet goes into a pool, and one lucky player wins the entire pool. Microgaming leads in this category.
🌀 Megaways Slots
The number of symbols on each reel changes with every spin, creating thousands of ways to win. This mechanic was invented by BTG (Big Time Gaming).
⛓️ Cascading Reels
When winning symbols disappear, new symbols fall from above — making it possible to win multiple times in a single spin. Available at PG Soft and Pragmatic Play.
🔷 Cluster Pays
You win when a set number of matching symbols land together — no paylines needed. NetEnt is well known for this mechanic.
Familiar Local Card Games
Online casinos offer many card games that have been popular in Bangladesh for years. At ck1771, these games can be played against live dealers and other players.
Teen Patti
Each player receives 3 cards. The player with the best hand wins. Teen Patti is played against other players.
Starting tip: begin with small bets and observe the card patterns of other players.
Andar Bahar
One card is placed face up in the middle. Cards are then dealt one by one to the left side (Andar) or the right side (Bahar). You bet on which side will first receive a card matching the middle card.
Starting tip: this is a probability-based game — playing with a live dealer makes it more enjoyable.
Callbreak
52 cards are dealt among 4 players. Before each round, you declare the number of tricks you expect to win and earn points accordingly.
Starting tip: Spades are always trump — if you have more Spades in hand, declare more tricks.
Ludo / Rummy
In online Ludo, you roll a dice to move your pieces. In Rummy, you form sequences of cards with the same number or the same suit. Both are played against other players.
Starting tip: in Rummy, focus on completing a pure sequence first.
Fishing & Arcade Games
Fishing games are one of the most entertaining categories in online casinos. At ck1771, you can play fishing games from JILI and other providers.
How Fishing Games Work
Fish of various sizes swim across the screen. You shoot at them with your cannon — each shot has a set cost. Killing bigger fish or boss fish earns more points and rewards. Raising the cannon level increases both the power and the cost of each shot.
Types of Arcade Games
- Classic Fishing: The classic shoot-and-catch mechanic, playable on any budget.
- Tournament Fishing: Earn as many points as possible within a set time — top scores win big rewards.
- Boss Fish Round: Take down special giant fish or monsters to win massive multiplier rewards.
- Multiplayer Fishing: Play at the same table as other players.
Tips for Controlling Costs
Always start at a low cannon level. Using a high cannon to shoot small fish wastes money. Raise the cannon level for boss fish — not for ordinary fish.
RTP and House Edge Explained
RTP (Return to Player) is the percentage of money returned to players over the long run in a game. If a slot has an RTP of 96%, it means an average of ৳96 is returned for every ৳100 wagered. However, this is an average calculated over millions of spins — results in a single session can be completely different.
The typical RTP ranges for different games are as follows: Slot games generally fall between 92% and 98% RTP. Blackjack can approach nearly 99% RTP when played with the correct strategy. Roulette has an RTP of around 97% in the European version, and slightly lower in the American version.
House edge is the opposite concept of RTP. If a game's RTP is 96%, the house edge is 4%. This means the game provider keeps an average of 4% from every bet. A high house edge can drain your balance quickly. So it is wise to choose games with a lower house edge.
RTP is a theoretical measure — it does not apply in the short term. Knowing the RTP of a game before you play helps you understand which games you can play for longer. But the most important thing is to set your own budget and play within it.
Bankroll Management Guide
Proper money management is the foundation of a responsible and enjoyable gaming experience. Setting a clear budget and sticking to it is the most important habit of an experienced player.
1. Set a Gaming Budget
At the start of the month, decide the maximum amount you can spend on entertainment. This amount should be money left over after your daily needs are covered — money you can afford to lose without affecting your lifestyle.
2. Divide into Sessions
Split your monthly budget into smaller sessions. For example, dividing your monthly budget into 3 or 4 sessions makes it clear how much you can spend per session and reduces the risk of spending it all in one day.
3. The 1–5% Rule per Bet
Use between 1% and a maximum of 5% of your total session balance on a single bet. Smaller bets make your session last longer and give you more chances to win big.
4. Stop After Winning Rule
Set a win target in advance. Once you reach that target, end the session. Continuing to play on a winning streak often results in losing all the winnings.
5. Set a Loss Limit
If you lose a set amount in a session, stop — placing more bets to recover losses almost always makes things worse. Step away from the "just one more" mindset.
6. Keep a Play History
Write down each session's deposits, wins, and losses in a simple notebook or phone note. Reviewing it regularly gives you a clear picture of your own playing patterns.
Keep in Mind
Gaming is entertainment, not a source of income. Playing within a budget increases enjoyment and reduces stress.
