MultiplayerCricket Format Explained
Cricket is the most popular sport in Bangladesh and also the most in-demand sport for betting. Each format has its own betting markets and strategies.
T20
20 overs per side, typically finishing in 3–4 hours. Betting markets: match winner, total runs, top batter, number of sixes per innings. BPL, IPL, BBL and PSL are played in this format.
One-Day (ODI)
50 overs per side, typically finishing in 7–8 hours. ODIs are played at the ICC World Cup and bilateral series. Betting markets: player performance, partnerships and powerplay runs.
Test Cricket
Five days, two innings per side — cricket's highest-prestige format. A wide variety of betting markets: draw, innings wickets, day-by-day markets.
The Hundred
100 balls per side — a new format from England. Very fast and spectator-friendly. Matches are shorter than T20, but betting markets are similar.
Leagues: BPL, IPL, BBL, PSL — these four leagues rank among the best T20 competitions in the world and you can bet on all of them at bk99tk.
How to Read Odds
Understanding odds is essential to successful betting. Learn how in plain language here.
Decimal Odds
Decimal odds are easy to understand — total return = stake × odds. ৳500 × 1.80 = ৳900 (profit ৳400). This is the most widely used format worldwide.
Implied Probability
Work out the probability from the odds: 1 ÷ odds × 100 = probability percentage.
If you believe the real probability is higher than the bookmaker's estimate, then that bet has value.
Other Formats
| Type | Example | Decimal |
|---|---|---|
| Fractional | 4/5 | 1.80 |
| American (−) | -125 | 1.80 |
| American (+) | +200 | 3.00 |
bk99tk generally uses the decimal format.
RTP and House Edge Explained
RTP (Return to Player) is the theoretical percentage of each ৳100 wagered that a game returns to players on average over the long term. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 bet — but this is the average across thousands of rounds, not the result of a single session.
RTP varies by game type. Slot games typically have an RTP between 92–98%. In blackjack, following the correct strategy can bring RTP up to around 99%. In roulette, RTP is generally between 94–97% — European roulette is more favourable than American.
House edge is the flip side of RTP. If a game has an RTP of 96%, the house edge is 4% — meaning the casino keeps an average of ৳4 for every ৳100 bet. This does not mean the game is unfair; it is the source of the operator's running costs and profit.
Understanding RTP before you play will help you make informed decisions — both in setting your entertainment budget and in choosing which game to play. Games with a lower house edge give you more playing time.
