Most Singapore sportsbooks — particularly SBOBET, available through platforms like BK8 and me88 — display odds in multiple formats simultaneously. A new bettor can switch between decimal, Malay, Hong Kong, and Indo odds in a single click, which is convenient but also confusing if you do not know what you are looking at. Understanding each format, and knowing how to convert between them, is essential before you place your first bet. This guide covers everything you need.
Decimal Odds — The Most Common Format in Singapore
Decimal odds are the default display for most Singapore bettors and the format used throughout this guide. The calculation is simple: total return = stake × decimal odds. The total return includes your original stake, so the profit is total return minus stake.
Example: You bet SGD 100 on a team at odds of 1.90. Your total return if the bet wins is SGD 190 — meaning your profit is SGD 90. If the odds are 2.00, a SGD 100 bet returns SGD 200 exactly (profit of SGD 100). Odds of 1.00 would return your stake only, which is why no legitimate bet is priced below 1.00 in decimal format.
Odds below 2.00 imply the outcome is more likely than not according to the sportsbook. Odds above 2.00 imply the outcome is considered less than a coin flip. This is the first piece of intuition worth building as a new bettor.
Asian Handicap Odds — How They Work and Why They Matter
Asian Handicap is the dominant format for football betting in Singapore. Instead of offering three outcomes (Win/Draw/Win), Asian Handicap reduces the market to two by giving one team a virtual head start. The draw is eliminated entirely or split across two possible outcomes.
The three main types are:
- Half-ball handicap (-0.5 / +0.5): The favourite must win outright. No draw outcome. Clean and simple.
- Quarter-ball handicap (-0.25 / +0.25): Your stake is split evenly across two adjacent lines. A draw result means you half-win or half-lose depending on which side you backed.
- Whole-number handicap (-1 / +1): If the result exactly matches the handicap line (e.g., favourite wins by exactly 1 when the handicap is -1), all stakes are refunded. This is called a push.
Asian Handicap odds typically sit close to 1.90 on both sides of a balanced line, reflecting a bookmaker margin of around 5%. This is significantly tighter than the margin on most 1X2 markets, making Asian Handicap better value for the bettor.
Malay Odds — What Positive and Negative Mean on SBOBET
SBOBET displays Malay odds as an alternative format, and it trips up many new Singapore bettors. The logic is as follows:
- Positive Malay odds (e.g., +0.90): This represents your profit per unit staked. A bet of SGD 100 at Malay odds of +0.90 returns SGD 90 profit (plus your SGD 100 stake back). Equivalent to decimal odds of 1.90.
- Negative Malay odds (e.g., -0.90): This means you must stake SGD 90 to win SGD 100 profit. If you bet SGD 100 at -0.90 and lose, you lose SGD 100. If you win, your profit is SGD 100 ÷ 0.90 = SGD 111.11. Equivalent to decimal odds of approximately 2.11.
To convert positive Malay odds to decimal: add 1. Malay +0.90 = decimal 1.90. To convert negative Malay odds to decimal: divide 1 by the absolute value and add 1. Malay -0.90 = (1 ÷ 0.90) + 1 = 2.11. Once you have the decimal equivalent, you can use the standard payout formula.
Implied Probability — Recognising Value in the Odds
Every set of decimal odds contains an implied probability — the sportsbook's assessment of how likely that outcome is. The formula is: implied probability = 1 ÷ decimal odds × 100.
Decimal odds of 2.10 imply a probability of 47.6%. If you believe a team's true chance of winning is 55%, those odds represent value — you are being offered a price better than the real probability suggests. Over many such bets, a genuine edge compounds into profit.
Sportsbooks build their margin by pricing each side of a market so that the combined implied probabilities add up to more than 100%. On a balanced Asian Handicap with both sides at 1.90, each side implies 52.6%, totalling 105.2%. The 5.2% excess is the bookmaker's edge. Recognising value means identifying cases where your assessment of the true probability beats the implied probability by enough to overcome that margin.
Quick Reference — Odds Format Comparison
| Decimal | Malay (positive) | Implied Probability | SGD 100 bet returns |
|---|---|---|---|
| 1.70 | +0.70 | 58.8% | SGD 170 |
| 1.90 | +0.90 | 52.6% | SGD 190 |
| 2.00 | +1.00 | 50.0% | SGD 200 |
| 2.50 | +1.50 | 40.0% | SGD 250 |
| 3.00 | +2.00 | 33.3% | SGD 300 |
Switch your SBOBET display to decimal odds if you are new — it is the most intuitive format and the one used in most Singapore betting guides. Once you are comfortable with the calculations, you can explore Malay odds to better understand how the platform presents favourites and underdogs in its Asian markets.
