Question 1

What is the difference between fractional and decimal odds?

Accepted Answer

Fractional odds (e.g., 5/1) show your potential profit relative to your stake — a £1 bet at 5/1 returns £5 profit plus your £1 stake. Decimal odds (e.g., 6.00) represent the total return per unit staked, including your original stake — a £1 bet at 6.00 returns £6 in total. Both formats convey the same information; the choice between them is purely a matter of personal preference. You can switch between formats in your account settings at any time without affecting your open bets or balance.

Question 2

How do I calculate potential winnings from an accumulator bet?

Accepted Answer

To calculate accumulator winnings, convert all your selections to decimal odds and multiply them together, then multiply the result by your stake. For example, if you have four selections at 2.00, 2.50, 3.00 and 4.00 decimal, multiply: 2.00 × 2.50 × 3.00 × 4.00 = 60.00. A £5 stake would return £300 in total (£295 profit plus your £5 stake). The bet slip will always calculate this automatically when you add selections, so you can see your potential returns clearly before confirming your wager.

Question 3

What does "odds-on" mean in betting?

Accepted Answer

Odds-on refers to a selection where the potential profit is less than the stake — in other words, you stake more than you win. In fractional terms, this is any price where the denominator is larger than the numerator, such as 1/2 (meaning a £2 stake wins only £1 profit). In decimal terms, odds-on means any price below 2.00. Odds-on selections are generally considered more likely to win, but they offer lower returns relative to the risk involved. You will commonly encounter odds-on prices in horse racing and in football matches where there is a clear favourite.

Question 4

How do each-way terms work for horse racing bets?

Accepted Answer

Each-way betting splits your stake into two equal parts — one on the selection to win, one on it to place. The place portion pays a fraction of the win odds (usually 1/4 or 1/5) if your horse finishes within the specified number of places. Place terms vary depending on the number of runners in the race and whether it's a handicap. For example, in a standard non-handicap race with 8+ runners, places are usually paid on the first three finishers at 1/4 of the win odds. Each-way terms are clearly displayed on every horse racing market so you always know exactly what you're betting on.

Question 5

What is the overround and how does it affect my bets?

Accepted Answer

The overround (also called the bookmaker's margin or vig) is the built-in profit margin included in all betting markets. It means that the implied probabilities of all possible outcomes in a market add up to more than 100%. For example, a two-outcome market might have individual implied probabilities of 52.4% each, totalling 104.8% — the extra 4.8% is the bookmaker's edge. While you can't eliminate this margin entirely, you can minimise its impact by seeking out markets with tighter pricing and identifying genuine value bets where you believe the probability of an outcome is higher than the odds suggest.

Question 6

Is this bookmaker legal and regulated for UK players?

Accepted Answer

Yes, the platform is fully licensed and regulated by the UK Gambling Commission (UKGC), which is the official regulatory body overseeing all gambling activity in Great Britain. This means the operator meets strict standards for player protection, fair play, responsible gambling and financial security. Online betting is legal in the UK for adults aged 18 and over. The UKGC licence ensures that all customer funds are held securely, that games and markets are fair, and that robust responsible gambling tools are in place. William Hill has operated in the UK betting market for decades and remains one of the most recognised and trusted names in the industry.
