Cricket Formats Explained
Understanding the differences between formats is important before placing cricket bets. Each format has its own market types and strategies.
T20
20 overs per innings, match ends in 3–4 hours. In this fast-paced format, innings totals, six counts, and Man of the Match markets are popular.
ODI (One-Day)
50 overs per innings, the match runs all day. Bettors show the most interest in innings score, partnership, and top batter markets.
Test
A five-day match with four innings. In this longer format, session results, draw bets, and series outcome markets are particularly appealing.
The Hundred
England's newer format — 100 balls per innings. Even faster than T20 and popular among younger fans.
Popular Leagues: Detailed markets for the Bangladesh Premier League (BPL) and IPL are available at ko333. Betting markets for BBL (Australia) and PSL (Pakistan) are also offered.
Jackpot Games
ko333 offers several types of jackpot games. Each has its own prize pool structure and winning conditions.
Progressive Jackpot Slots
A portion of every bet goes into the pool. The more players bet, the larger the prize grows — the jackpot triggers on a special combination.
Live Casino Side-Bet Jackpot
Placing a side bet at a Baccarat or Blackjack table can earn an additional jackpot when a special card combination appears.
Crash Game Multiplier
In crash games like Aviator, the multiplier keeps rising. Cash out at the right time to claim a large multiplied payout.
Fishing Game Mega Prizes
Catch special fish in JILI's Mega Fishing and Jackpot Fishing to win mega prizes drawn from a shared pool.
How to Read Odds
Understanding odds is the most important skill in sports betting. Three main formats are used around the world.
Decimal Odds
The most common format in Bangladesh. Your total return = stake × odds.
Example: ৳500 bet, odds 1.80 → total return ৳900 (profit ৳400).
Fractional Odds
Common in the British tradition. 4/1 means ৳4 profit for every ৳1 staked. So a ৳500 bet returns ৳2,000 profit, with a total return of ৳2,500.
American Odds (Moneyline)
+150 means ৳150 profit on a ৳100 bet; -150 means you need to stake ৳150 to win ৳100. Many bettors in Dhaka are now comfortable with this format too.
Implied Probability: Odds of 2.00 = 50% probability; odds of 1.50 = 66.7%. The lower the odds, the higher the market considers the probability of that outcome.
Live Casino Tables
At ko333's live casino, real dealers run the games via live video. Table limits are flexible — suitable for both new and experienced players.
Baccarat
The most popular live game in South Asia. Bet on Player, Banker, or Tie. The rules are simple and each round ends quickly.
Roulette
Both European and American Roulette are available. Bet on numbers, colors, or sectors — the live dealer spins the wheel to determine the result.
Blackjack
Reach 21 or beat the dealer. Use Hit, Stand, and Double Down strategies to improve your chances of winning with skill.
Live Andar Bahar
A classic card game from the Indian subcontinent — guess whether a matching card appears on the Andar or Bahar side first. Fast and fun.
Game Show Wheel
A colorful money-wheel game hosted by a live host. Landing on a multiplier or bonus slot can bring a big prize — and it looks great too.
Live Dragon Tiger
Guess which of two cards is higher. A simplified version of Baccarat — each round is over in just a few seconds.
RTP and House Edge Explained
RTP (Return to Player) is the long-term average percentage of money that is theoretically returned to players in a game. For example, a 96% RTP means that over the long term, an average of ৳96 is returned for every ৳100 wagered — but results in any single session can vary widely.
House edge is the flip side of RTP. A 96% RTP means a house edge of 4% — the casino keeps an average of 4% of every bet. Typical RTP ranges by game type are as follows:
| Game Type | Typical RTP Range |
|---|---|
| Slot Games | 92% – 98% |
| Blackjack | ~99% (with optimal strategy) |
| Roulette (European) | 94% – 97% |
| Baccarat (Banker) | ~98.9% |
| Crash Games | Up to 97% |
RTP is a statistical average — it does not guarantee short-term results. Understanding volatility is also important: high-volatility games pay out larger wins less frequently, while low-volatility games pay out smaller wins more often. Setting a budget before playing is the first step toward responsible gaming.

Set a Budget
Before you play, set a weekly or monthly limit for yourself. Never bet more than you can afford to lose.

If you feel the need, put your account on a break for a set period. Our support team will assist you with this.
