Open an Account at gb99A Simple Guide to Understanding Betting Odds
There are three types of odds formats in cricket betting. From Dhaka to Kolkata — Decimal format is the most common on most sites across Asia. Below is an explanation of all three formats.
Decimal Odds
The simplest calculation — multiply your stake by the odds to get the total return. For example, ৳500 × 3.00 = ৳1,500.
Team A to win — the same value in three formats:
Decimal: 3.00 = Fractional: 2/1 = American: +200
If you win a ৳500 bet, you get back ৳1,500 (profit ৳1,000 + original stake ৳500); if you lose, ৳500 is gone.
Fractional Odds
In the European format, the fraction represents profit/stake. 2/1 means ৳2 profit on a ৳1 bet. For heavy favourites, the numbers are reversed (1/4).
Team B is the favourite:
Decimal: 1.25 = Fractional: 1/4 = American: -400
If you win a ৳500 bet, you get back ৳625 (profit ৳125). American -400 means you need to bet ৳400 to make ৳100 profit.
American Odds
A + sign means how much profit you make per ৳100 bet; a - sign means how much you need to bet to make ৳100 profit. This format is common on American sites.
+200 → ৳200 profit on a ৳100 bet.
-400 → ৳400 bet required to make ৳100 profit.
All three formats express the same value — only the way they are written differs.
Bet within your means and avoid placing extra bets to recover losses.
Slot RTP and Volatility Basics
RTP (Return to Player) is the average return calculated over billions of spins — it is not a guaranteed return for any single session. Slot game RTP typically falls between 94–97%. For example, Fortune Mouse (PG Soft) has a maximum RTP of 96.96%, meaning an average of ৳96.96 may be returned for every ৳100 wagered — but results in any individual session can vary.
RTP of Some Well-Known Games
- Fortune Mouse (PG Soft) — Maximum RTP 96.96%
- Mahjong King (CQ9 Gaming) — Maximum RTP 97.20%
- White Rabbit Megaways (Big Time Gaming) — Maximum RTP 97.72%
- Aviator (Spribe) — Maximum RTP 97%
- Super Ace (JILI) — Maximum RTP 97%
How Does a Progressive Jackpot Grow?
A small portion of every bet goes into the jackpot pool. The more people play, the faster the pool grows. The jackpot is usually triggered by special trigger symbols or the maximum bet.
Low Volatility
Pays out small rewards frequently. Your balance can last longer. Good for players who want to play for more time. Example: Fortune Gems (JILI).
Medium Volatility
A mix of small and medium rewards. A good balance for most players. Examples: Fortune Tiger (PG Soft), Super Ace (JILI).
High Volatility
Large rewards may come after a long dry run. Requires a bigger budget and patience. Examples: Gates of Olympus, Wanted Dead or a Wild.
Choose a volatility level that suits your budget — do not spend beyond your limit chasing a big win.
