Understanding how to read and compare odds is one of the most essential skills for any successful bettor. When using betting sites not on GamStop, knowing how to interpret odds accurately can help you maximize your winnings and find the best value bets.
Unlike UKGC-regulated bookmakers, non-GamStop betting sites often offer higher odds, better payouts, and unique betting markets. However, since these sportsbooks operate under different regulatory frameworks, odds formats and calculations may vary from what UK bettors are used to.
In this comprehensive guide, you’ll learn:
✔ How to read different types of odds (Decimal, Fractional, American)
✔ How to compare odds across multiple sportsbooks
✔ Why non-GamStop betting sites often offer better odds
✔ How to calculate payouts and implied probability
✔ Top betting sites not on GamStop with the best odds
Understanding Different Types of Betting Odds
Betting sites around the world display odds in different formats. The three most common types are:
1️⃣ Decimal Odds (Used in Europe & non-GamStop bookies)
2️⃣ Fractional Odds (Used by traditional UK bookmakers)
3️⃣ American Odds (Used in the U.S. market)
1. Decimal Odds (European Format)
Decimal odds are the most common format used by non-GamStop betting sites. They are simple to understand and calculate winnings.
✔ Example:
If a team has odds of 2.50, this means:
- A £10 bet would return £25 total (£10 x 2.50)
- The profit would be £15 (£25 – £10 stake)
💡 Formula to calculate winnings:
👉 Total payout = Stake × Decimal Odds
2. Fractional Odds (UK Format)
Fractional odds are the traditional format used in UK bookmakers (e.g., Bet365, William Hill). Many offshore sportsbooks also offer this format to cater to UK players.
✔ Example:
If the odds are 5/2, this means:
- For every £2 staked, you win £5 profit
- A £10 bet would return £35 total (£10 × 5/2 + £10 stake)
💡 Formula to calculate winnings:
👉 Profit = (Stake × Numerator) / Denominator
3. American Odds (Moneyline Format)
American odds are mostly used in U.S. sportsbooks but are also found on some non-GamStop betting sites.
There are two types of Moneyline odds:
✅ Positive odds (+200, +150, etc.) – Show how much profit you make on a £100 bet
✅ Negative odds (-150, -200, etc.) – Show how much you need to bet to win £100 profit
✔ Example:
- +200 means a £100 bet returns £300 total (£200 profit)
- -150 means you need to bet £150 to win £100 profit
💡 Formula for positive odds (+):
👉 Profit = (Stake × Odds) / 100
💡 Formula for negative odds (-):
👉 Profit = (Stake × 100) / Odds
How to Compare Odds Across Non-GamStop Betting Sites
To maximize your winnings, you should always compare odds between multiple sportsbooks. Since offshore betting sites operate without UKGC restrictions, they often offer better odds and higher payouts than UK bookies.
1. Use an Odds Comparison Tool
Websites like OddsPortal and OddsChecker allow you to compare odds for different events across multiple bookies.
Example: If you want to bet on Manchester City to win the Champions League, the odds might look like this:
| Bookmaker | Odds (Decimal Format) | Potential Profit on £100 Bet |
|---|---|---|
| Bet365 (UKGC) | 3.00 | £200 |
| GoldenBet (Non-GamStop) | 3.50 | £250 |
| Mystake (Non-GamStop) | 3.60 | £260 |
| Rolletto (Non-GamStop) | 3.75 | £275 |
As seen above, non-GamStop sportsbooks provide significantly better value compared to UKGC-regulated sites.
2. Look for Lower Bookmaker Margins
Bookmakers apply a margin (also known as vigorish or overround) to ensure they make a profit regardless of the outcome.
A low-margin bookmaker offers better odds to bettors. You can calculate the margin using this formula:
👉 (1/Decimal Odds for Team A) + (1/Decimal Odds for Team B) + (1/Decimal Odds for Draw) × 100
A fair market should have bookmakers not on gamstop a margin below 5%, while some UK bookies take up to 8-10%. Many non-GamStop sportsbooks offer lower margins, increasing your potential profits.
3. Check for Enhanced Odds Promotions
Many offshore betting sites offer boosted odds promotions to attract players. These can be found under:
✔ “Super Boost” or “Odds Boost” sections
✔ Limited-time promotions on major events
Why Non-GamStop Betting Sites Offer Better Odds
💰 Higher odds = Higher payouts 💰
✅ 1. No UKGC Restrictions
Non-GamStop bookies operate under offshore licenses (e.g., Curacao, Malta), allowing them to offer better odds and higher betting limits.
✅ 2. Lower Operating Costs
Since offshore bookies don’t have to pay high UKGC fees, they pass these savings on to players through better odds.
✅ 3. More Betting Markets
Non-GamStop sites often offer:
✔ Unique player prop bets
✔ Higher odds on underdogs
✔ Alternative betting markets not available in the UK
