- Malay odds are the default format on most Malaysian sportsbooks — they range from -1.00 to +1.00 and work differently from Western formats.
- Decimal odds are the simplest to understand: stake x odds = total return (including your original stake).
- All odds formats express the same information differently — once you understand one, converting to others is straightforward arithmetic.
- Implied probability is the key concept: it tells you what chance the sportsbook is pricing into the odds, so you can compare it against your own assessment.
- Finding value (odds that underestimate the true probability) is the only sustainable path to long-term betting profit.
What Are Betting Odds?
Betting odds serve two purposes: they tell you how much you will win if your bet is successful, and they reflect the sportsbook's assessment of how likely each outcome is. Understanding both functions is fundamental to becoming a better bettor.
When you see odds displayed on Maxim88 or any other sportsbook, those numbers represent the relationship between risk and reward. Higher odds mean a bigger potential payout but indicate a less likely outcome. Lower odds mean a smaller payout but a higher probability of winning.
The challenge for Malaysian bettors is that odds come in several different formats — Malay, decimal, Hong Kong, Indonesian, fractional, and American. Different sportsbooks and different markets use different formats, so understanding all of them makes you a more versatile bettor. Most Malaysian sportsbooks default to Malay odds for Asian markets but offer other formats that you can switch to in your account settings.
Decimal Odds Explained
Decimal odds are the simplest format and the best starting point for beginners. They represent the total return for every 1 unit staked, including your original stake.
How to read them: If the decimal odds are 2.50, a winning RM 100 bet returns RM 250 total (RM 100 stake + RM 150 profit).
The formula: Total Return = Stake x Decimal Odds
Profit: Profit = Stake x (Decimal Odds - 1)
- 1.50 odds: RM 100 bet returns RM 150 (RM 50 profit). This is a favourite — implied probability 66.7%.
- 2.00 odds: RM 100 bet returns RM 200 (RM 100 profit). An even-money bet — implied probability 50%.
- 3.00 odds: RM 100 bet returns RM 300 (RM 200 profit). An underdog — implied probability 33.3%.
- 5.00 odds: RM 100 bet returns RM 500 (RM 400 profit). A long shot — implied probability 20%.
Decimal odds always include your stake in the return. An odds of 1.00 means you get your money back with zero profit. Anything below 1.00 means you lose money even if you win (this only happens in specific arbitrage scenarios and is rare).
Malay Odds Explained
Malay odds are the most common format on Malaysian sportsbooks and the format most local bettors encounter first. They range from -1.00 to +1.00 and work differently depending on whether the number is positive or negative.
Positive Malay odds (+0.01 to +1.00) — the underdog:
Positive Malay odds show how much profit you make on a 1-unit stake. If the Malay odds are +0.80, a RM 100 bet returns RM 180 total (RM 100 stake + RM 80 profit). If you lose, you lose your full RM 100 stake.
Formula: Profit = Stake x Malay Odds
Negative Malay odds (-0.01 to -1.00) — the favourite:
Negative Malay odds show how much you must risk to profit 1 unit. If the Malay odds are -0.80, a RM 80 bet profits RM 100 if you win. But if you lose, you only lose RM 80 (not the full potential payout). This is the key difference from American odds — in Malay odds, your loss is always limited to your stake.
More practically: With -0.80 Malay odds and a RM 100 bet, if you win, you profit RM 100 (your stake is returned plus RM 100 profit). If you lose, you lose RM 80 (not your full RM 100 stake — only |odds| x stake).
- +0.90: Stake RM 100. Win = RM 190 returned (RM 90 profit). Lose = lose RM 100.
- +0.50: Stake RM 100. Win = RM 150 returned (RM 50 profit). Lose = lose RM 100.
- -0.50: Stake RM 100. Win = RM 200 returned (RM 100 profit). Lose = lose RM 50.
- -0.90: Stake RM 100. Win = RM 200 returned (RM 100 profit). Lose = lose RM 90.
The key insight with Malay odds: negative odds protect your downside. When you bet on a favourite with -0.80 odds, you do not lose your full stake — you only lose 80% of it. This makes Malay odds psychologically different from decimal or American odds, where you always lose your entire stake on a loss.
Hong Kong Odds Explained
Hong Kong odds are simple and commonly offered alongside Malay odds on Asian sportsbooks. They show your net profit on a 1-unit stake — similar to decimal odds, but without including the original stake in the number.
How to read them: If Hong Kong odds are 0.80, a RM 100 bet profits RM 80. Your total return is RM 180 (RM 100 stake + RM 80 profit).
Formula: Profit = Stake x Hong Kong Odds. Total Return = Stake x (Hong Kong Odds + 1).
Hong Kong odds are always positive. An odds of 1.00 is an even-money bet. Below 1.00 is a favourite, above 1.00 is an underdog. Converting to decimal is trivial: just add 1 (HK 0.80 = Decimal 1.80).
Indonesian Odds Explained
Indonesian odds look similar to American odds but use a different base. They can be positive or negative and are commonly available on Southeast Asian sportsbooks.
Positive Indonesian odds show profit on a 1-unit stake. +1.50 means a RM 100 bet profits RM 150 (same as HK odds above 1.00).
Negative Indonesian odds show how much you must stake to profit 1 unit. -1.50 means you stake RM 150 to profit RM 100. If you lose, you lose your full RM 150 stake (unlike Malay odds, where losses are capped).
Indonesian odds above +1.00 or below -1.00 simply extend the same logic. They are essentially the reciprocal of each other: +1.50 and -1.50 represent opposite sides of the same market.
Fractional and American Odds
Fractional odds (e.g., 3/1, 5/2) are the traditional British format. The first number shows potential profit, the second shows the stake required. 3/1 means you profit RM 3 for every RM 1 staked. 5/2 means you profit RM 5 for every RM 2 staked (or RM 250 profit on a RM 100 bet).
Fractional odds are primarily used in UK horse racing and some football markets. Malaysian bettors will encounter them occasionally but rarely need them as a primary format.
American odds (e.g., +150, -200) are the standard format in the United States. Positive American odds show profit on a USD 100 stake (+150 means RM 150 profit on RM 100). Negative American odds show how much you must stake to profit USD 100 (-200 means you stake RM 200 to profit RM 100).
American odds are uncommon on Malaysian sportsbooks but appear on some international platforms. The key difference from Malay odds: with negative American odds, you lose your full stake on a loss. With negative Malay odds, your loss is proportionally reduced.
How to Convert Between Odds Formats
Being able to convert odds quickly helps you compare prices across different sportsbooks. Here are the key conversion formulas.
Malay to Decimal:
- Positive Malay: Decimal = Malay + 1 (e.g., +0.80 = 1.80)
- Negative Malay: Decimal = (1 / |Malay|) + 1 (e.g., -0.80 = 1/0.80 + 1 = 2.25)
Decimal to Malay:
- Decimal below 2.00: Malay = Decimal - 1 (e.g., 1.75 = +0.75)
- Decimal above 2.00: Malay = -1 / (Decimal - 1) (e.g., 2.50 = -1/1.50 = -0.67)
Hong Kong to Decimal: Decimal = HK + 1 (always)
Decimal to Implied Probability: Probability = 1 / Decimal Odds x 100% (e.g., 2.50 = 1/2.50 = 40%)
- Favourite (66.7% implied): Decimal 1.50 | Malay -0.67 | HK 0.50 | Indonesian -2.00 | Fractional 1/2 | American -200
- Even money (50%): Decimal 2.00 | Malay -1.00 / +1.00 | HK 1.00 | Indonesian +1.00 / -1.00 | Fractional 1/1 | American +100
- Underdog (40%): Decimal 2.50 | Malay -0.67 | HK 1.50 | Indonesian +1.50 | Fractional 3/2 | American +150
- Long shot (25%): Decimal 4.00 | Malay -0.33 | HK 3.00 | Indonesian +3.00 | Fractional 3/1 | American +300
Understanding Implied Probability
Implied probability is the most important concept in this entire guide. It converts odds into a percentage that represents the sportsbook's assessment of how likely each outcome is.
Why it matters: Odds alone do not tell you whether a bet is good or bad. A 1.50 odds bet on a heavy favourite might seem "safe," but if the true probability is only 60% while the odds imply 66.7%, you are actually getting a bad deal. Conversely, a 5.00 odds longshot might seem "risky," but if the true probability is 25% while the odds imply only 20%, that is a profitable bet over time.
The formula: Implied Probability = 1 / Decimal Odds
For Malay odds, convert to decimal first, then apply the formula.
The overround: If you add up the implied probabilities for all outcomes in a market, the total will exceed 100%. The excess is the sportsbook's margin (also called the "vig" or "juice"). For example, in a two-way market, the implied probabilities might be 55% and 50% — totalling 105%. The 5% overround is the sportsbook's built-in profit margin. Lower overrounds mean better odds for bettors. Maxim88 consistently offers competitive margins across its markets.
How to Find Value Bets
Value betting is the only sustainable strategy for long-term profit. A value bet exists when the probability you assign to an outcome is higher than the implied probability of the odds.
Example: You believe Team A has a 60% chance of beating Team B. The sportsbook offers 1.80 decimal odds on Team A, which implies a 55.6% probability. Since your estimated probability (60%) is higher than the implied probability (55.6%), this is a value bet. Over many such bets, you will profit.
Finding value requires two skills:
- Accurate probability estimation: This comes from research, data analysis, and deep knowledge of the sport or market you are betting on. The more accurately you can assess the true probability of outcomes, the more value opportunities you will identify.
- Understanding odds and markets: You need to quickly calculate implied probability from any odds format and compare it against your assessment. You also need to understand that odds move based on betting volume — early odds (opening lines) are often softer than closing lines.
Practical tips for finding value:
- Specialise: You cannot accurately assess probabilities across all sports and markets. Focus on 1-2 sports or leagues where your knowledge gives you an edge over the general betting public.
- Bet early: Opening lines often contain more value than closing lines. If you have done your research, placing bets when lines first open can lock in better odds before the market corrects.
- Compare odds: Different sportsbooks price the same events differently. Having accounts on multiple platforms and consistently choosing the best available odds adds up significantly over time.
- Track your results: Record every bet with your estimated probability and the actual outcome. Over hundreds of bets, this data reveals whether your probability estimates are accurate or need calibration.
Understanding odds is the foundation of successful betting. Whether you use Malay, decimal, or any other format, the underlying principle is the same: find situations where the odds underestimate the true probability, bet consistently on those situations, and let the mathematics work in your favour over time.
