Spin-kings Odds Format: Decimal, Fractional, American
Understanding Decimal Odds at Spin-kings
Decimal odds are the most straightforward format used by Spin-kings. They represent the total payout per unit stake, including your original wager. For example, odds of 2.50 mean that for every $1 you bet, you receive $2.50 back if you win – a profit of $1.50. At Spin-kings, decimal odds are the default for most sports markets, such as football, tennis, and basketball. Typical RTP numbers in casino games are separate, but for sports, the theoretical return can be calculated by the inverse of the odds. A market with odds of 1.91 implies an implied probability of about 52.4%, though the actual RTP depends on the margin. Minimum bets start from $0.10 for most events, with maximum limits varying by sport and league (e.g., 10,000 USD on major soccer matches). To switch to decimal view, go to your account settings and select “Decimal” under odds format – the change takes effect immediately.

Fractional Odds Explained
Fractional odds, popular in the UK and Ireland, show the profit relative to the stake. For instance, 5/1 means you win $5 for every $1 bet, plus your stake back. For odds shorter than even money, say 2/5, you must bet $5 to win $2. At spin-kings, you can enable fractional odds in the display settings. This format is often used for horse racing and greyhound events. When you see a fractional odds line, remember to divide the numerator by the denominator to get the decimal equivalent – this is helpful for comparing with other markets. The platform supports fractional odds up to 999/1 for prop bets, with maximum payouts capped at 500,000 USD per bet. Keep in mind that fractional odds do not automatically include the stake; always add 1 to the fraction to get the decimal multiplier.
American Odds: How They Work
American odds (also known as moneyline odds) are expressed as either a positive or negative number. Positive odds (e.g., +200) indicate how much profit you make on a $100 bet – a $100 bet at +200 returns $300 total ($200 profit + $100 stake). Negative odds (e.g., -150) show how much you must bet to win $100 – a $150 bet at -150 returns $250 total ($100 profit + $150 stake). Spin-kings casino lists American odds for US-facing markets, especially for major leagues like the NFL and NBA. The implied probability for +200 is 33.33%, while for -150 it is 60%. This format is useful for identifying underdogs and favourites at a glance. At Spin-kings casino, you can filter odds by format on any event page, and the conversion happens server‑side, so no page reload is needed. Minimum stakes remain the same regardless of format.
Converting Between Odds Formats
Knowing how to convert odds gives you a better understanding of value. Here is a simple list of steps for manual conversion:
- Decimal to Fractional: Subtract 1, then express as a fraction in simplest form (e.g., Decimal 3.25 → 3.25 – 1 = 2.25 = 9/4).
- Fractional to Decimal: Divide the numerator by the denominator and add 1 (e.g., 5/2 → 5÷2 = 2.5 + 1 = 3.50).
- Decimal to American: If Decimal ≥ 2.00, multiply (Decimal – 1) × 100 for positive odds; if < 2.00, use -100 ÷ (Decimal – 1) for negative odds.
- American to Decimal: For positive odds, divide by 100 and add 1; for negative odds, divide 100 by the absolute odds and add 1.
Using the Spin-kings bonus calculator on the site can automate these conversions. For example, if you receive a 100% match bonus up to $500, knowing the odds formats helps you estimate potential winnings from qualifying bets. The conversion table below summarises common examples.
| Decimal | Fractional | American |
|---|---|---|
| 1.50 | 1/2 | -200 |
| 2.00 | 1/1 | +100 |
| 4.00 | 3/1 | +300 |
| 1.25 | 1/4 | -400 |
| 10.00 | 9/1 | +900 |
