1win Betting Odds Guide: Decimal, Malay, Hong Kong and Indonesian

Four odds formats sit behind odds settings on the platform: Decimal, Malay (Malaysian), Hong Kong, and Indonesian. All four describe the exact same underlying price. They’re just displayed with a different number and, for two of them, a possible plus or minus sign. Same price, different labels. This page walks through how each format reads, how a stake turns into a return under each one, and how implied probability connects back to all four once converted to a decimal equivalent. Every number used below is a generic, illustrative example, not a real current match price. For the current sports and markets available to apply this to, the sportsbook page is the place to check.

Key Takeaways

• Decimal odds, Malay (Malaysian) odds, Hong Kong odds and Indonesian odds are four ways of displaying the exact same underlying price.
• Decimal is the most direct to calculate: return equals stake multiplied by the decimal figure.
• Malay odds use a sign. Positive figures work like a fraction of the stake; negative figures work as stake divided by the figure’s size.
• Hong Kong odds represent profit per unit stake directly, and Indonesian odds work similarly to Malay but on a different scale.
• Implied probability is always 1 divided by the decimal equivalent, whichever format a price started in.

Understanding What an Odds Number Represents

An odds figure, in any of the four formats, is a compact way of expressing two things at once: how much a winning stake pays back, and how likely that outcome is considered to be. A shorter price generally reflects a more expected outcome and pays back less per unit staked. A longer price reflects a less expected outcome and pays back more.

None of the four formats changes the underlying price itself, only how it’s written down. A Decimal figure, a Malay figure, a Hong Kong figure and an Indonesian figure can all describe the exact same bet at the exact same real-world price, which is why converting between them correctly always lands on the same profit, return and implied probability.

Decimal Odds: The Base Format

Decimal odds are the most direct of the four formats to calculate by hand. Total return equals stake multiplied by the decimal figure. Profit equals stake multiplied by the decimal figure minus one, since the stake itself is already included in the return.

Worked example: decimal odds of 2.50 with a stake of RM100. Return is 100 multiplied by 2.50, which is RM250. Profit is 100 multiplied by (2.50 minus 1), which is 100 multiplied by 1.50, giving RM150. Checking the two figures against each other: RM150 profit plus the original RM100 stake equals RM250, matching the return figure exactly. The numbers check out.

Implied probability from a decimal figure is 1 divided by the decimal odds. For the 2.50 example above, that’s 1 divided by 2.50, which equals 0.40, or 40%. The same implied-probability calculation applies once any of the other three formats below has been converted back to its decimal equivalent.

Malay (Malaysian) Odds: The Locally Relevant Format

Malay odds are the format most likely to feel familiar to a Malaysian player, and they work a little differently depending on whether the figure shown carries a plus or a minus sign.

If the Malay figure is positive (greater than zero), profit equals stake multiplied by that figure, and total return equals stake multiplied by (1 plus that figure). Worked example: Malay odds of +0.80 with a stake of RM100. Profit is 100 multiplied by 0.80, which is RM80. Return is 100 multiplied by (1 plus 0.80), which is 100 multiplied by 1.80, giving RM180. Checked against each other: RM80 profit plus the RM100 stake equals RM180, matching. The decimal equivalent of this price is 1 plus 0.80, which is 1.80.

If the Malay figure is negative (less than zero), profit equals stake divided by the absolute value of that figure, and total return equals stake plus that profit. Worked example: Malay odds of -1.25 with a stake of RM100. Profit is 100 divided by 1.25, which is RM80. Return is 100 plus 80, which is RM180. This lands on exactly the same RM80 profit, the same RM180 return, and the same 1.80 decimal equivalent as the positive example above, since 1 plus (1 divided by 1.25) also equals 1.80. Both worked examples describe the same underlying price shown from opposite sides: a positive figure under 1 mirrors a negative figure with the equivalent magnitude on the other side of even money.

As a rule of thumb, Malay odds with a size greater than 1 are shown as negative (typically the favorite), and Malay odds with a size of 1 or less are shown as positive (typically the underdog). This roughly mirrors how decimal odds above or below 2.00 are usually thought of.

Hong Kong Odds

Hong Kong odds are numerically equal to the decimal figure minus one, which means the Hong Kong number represents profit per unit stake directly, without needing to subtract anything first. Profit equals stake multiplied by the Hong Kong figure. Total return equals stake multiplied by (the Hong Kong figure plus 1).

Worked example: Hong Kong odds of 1.50 with a stake of RM100. Profit is 100 multiplied by 1.50, which is RM150. Return is 100 multiplied by (1.50 plus 1), which is 100 multiplied by 2.50, giving RM250. The equivalent decimal odds figure is 1.50 plus 1, which is 2.50, the exact same price used in the Decimal Odds section above. The profit and return figures match exactly (RM150 profit, RM250 return) because it’s the same underlying price expressed in a different format. Same price, new label.

Indonesian Odds

Indonesian odds follow a similar positive/negative structure to Malay odds, but scaled differently, so the same sign logic applies with a slightly different formula underneath.

If the Indonesian figure is positive (shown as 1.00 or higher), profit equals stake multiplied by that figure, and total return equals stake multiplied by (1 plus that figure). Worked example: Indonesian odds of +1.50 with a stake of RM100. Profit is 100 multiplied by 1.50, which is RM150. Return is 100 multiplied by (1 plus 1.50), which is 100 multiplied by 2.50, giving RM250. That matches the Decimal 2.50 and Hong Kong 1.50 examples above exactly, since all three describe the same underlying price.

If the Indonesian figure is negative (shown as -1.00 or lower), profit equals stake divided by the absolute value of that figure, and total return equals stake multiplied by (1 plus 1 divided by the absolute value of that figure). Worked example: Indonesian odds of -2.00 with a stake of RM100. Profit is 100 divided by 2.00, which is RM50. Return is 100 multiplied by (1 plus 1 divided by 2.00), which is 100 multiplied by 1.50, giving RM150. Checked against each other: RM50 profit plus the RM100 stake equals RM150, matching. The decimal equivalent here is 1 plus (1 divided by 2.00), which is 1.50.

Implied Probability Across All Four Formats

Implied probability is the market’s way of expressing how likely an outcome is considered, purely as a function of the price: 1 divided by the decimal odds figure. This calculation only works directly on a decimal figure, which is exactly why converting any Malay, Hong Kong or Indonesian figure back to its decimal equivalent first is the reliable way to get an implied probability out of any of the four formats.

Using the shared price from three of the worked examples above (Decimal 2.50, Hong Kong 1.50, Indonesian +1.50, all the same underlying price), implied probability comes out to 1 divided by 2.50, which is 0.40, or 40%, in all three cases. That consistency is exactly the point: the four formats are different displays of the same price, so the implied probability behind them is identical once each is converted properly.

Using the shared price from the Malay examples (decimal equivalent 1.80), implied probability is 1 divided by 1.80, which comes out to approximately 0.556, or roughly 55.6%. None of this is a prediction of what will actually happen. It’s simply what the price itself implies mathematically, and it says nothing about whether a given selection is a good idea to back.

Display Settings and Odds in Esports Markets

The format that shows up by default, and how many decimal places it’s shown to, can differ by interface or account settings rather than being fixed for every player. Since all four formats are supported, switching between them is usually just a display preference, not a change to the underlying price itself.

The same math applies just as directly to esports markets as it does to traditional sports. A match-winner price for a Dota 2 series or a map-handicap price for a CS2 match still converts through exactly the same Decimal, Malay, Hong Kong and Indonesian formulas covered above. The format doesn’t change based on what’s being bet on, only the price itself does. For the fuller picture of what’s available to bet on for each title specifically, the Dota 2 page and the CS2 page cover that in more depth than this page needs to.
