How to bet on tennis matches: Guide

New to Wolfbet? Watch our short first. It shows you how to find a match and place your bet.

This is a quick guide to how to bet on tennis. A match is scored in points, games and sets, and it is played as best of three or best of five sets. A set goes to the first player with six games and a lead of two. If the games reach six all, a tiebreak decides it. Because a match has several parts, you can bet on the whole match or on a single set. We use one real market from Wolfbet to show how it works.

How to play: betting in three steps

1. Pick a match and a market.
2. Press the odds of the selection you want.
3. Enter your stake and confirm.

Your return follows one formula: stake × decimal odds. Profit is return − stake. Every example here uses a stake of 10 units, with no currency, so the maths works anywhere.

A real example: Olivia Cela vs Athena Orzechowski

Each section below starts from one row of this screen.

[screenshot: 1 Set Winner market, Olivia Cela 2.07, Athena Orzechowski 1.63]

1 Set Winner

The 1 Set Winner block on the screen has two buttons, one per player. Cela is at 2.07 and Orzechowski at 1.63. The bet covers the first set only. The final result of the match does not matter, and neither does what happens after the first set ends.

A 10 unit stake on Cela at 2.07 returns 10 × 2.07 = 20.70, a profit of 10.70. The same stake on Orzechowski at 1.63 returns 16.30, a profit of 6.30. If your player loses the set, you lose the 10 units.

Compare the two buttons. The shorter price on Orzechowski means the market rates her as the likelier set winner. Backing Cela pays 4.40 more profit on the same stake, because the risk is higher.

If a player retires before the set is finished, what happens to your bet depends on the operator’s rules. Read the market rules before you bet.

Other markets you may come across

Tennis offers more than a set winner. Here are the common ones, with the rules only.

• Match winner. You pick who wins the whole match. There are two selections because a match always has a winner.
• Handicap. A handicap is set in games or in sets. The favourite starts with a negative line. A line of −4.5 games means the favourite must win by at least five games overall.
• Total games. The bookmaker sets a line and you bet over or under the combined games played by both players.
• Correct score in sets. You predict the exact set score, for example 2 to 0 in a best of three match. It is harder to hit, so it pays more than a match winner bet.
• Tiebreak markets. These cover whether a tiebreak happens in a set or in the match.
• Player props. An example is the number of aces a player serves.
• Outrights. You back a player to win a whole tournament.
• Live markets. These include the next game or the next set, and their odds update as the match goes on.

How to read odds

Decimal odds show your total return per 1 unit staked, stake included. At 2.07, one unit returns 2.07.

Implied probability is the chance the price suggests: 1 ÷ decimal odds.

Add the two: 48.31% + 61.35% = 109.66%. A market with no margin would total exactly 100%. The extra 9.66 points is the bookmaker margin, also called the overround. The lower it is, the better the price you get.

American odds show the same price differently. For decimal odds of 2.00 or more, the formula is (decimal − 1) × 100. Below 2.00, it is −100 ÷ (decimal − 1). A negative number tells you how much to stake to win 100.

From predictions to best bets

A prediction becomes one of the best bets only when the price is better than your own estimate says it should be.

First, remove the margin. Divide each implied probability by the total of 109.66%. Cela comes to 44.05% and Orzechowski to 55.95%, which are fair odds of about 2.27 and 1.79.

Now an example, not a forecast. Say your own prediction is that Cela wins the first set 50% of the time. Fair odds for 50% are 2.00, and Wolfbet offers 2.07, so the price is above your number. Over many bets, a 10 unit stake would average 10 × 0.5 × 2.07 = 10.35 back, a gain of 0.35. If you rated her at 40%, the average return would be 10 × 0.4 × 2.07 = 8.28, below your stake, so you would skip the bet.

Value only describes the long run. Any single bet can still lose.

How to win more bets

No check guarantees a win. These ones stop you from guessing:

• Which market are you betting on, and what does it cover? A set winner bet ignores the rest of the match.
• How many sets does the match have? Best of three and best of five change totals, handicaps and set scores.
• What do the surface, recent form, head to head record and fitness look like for these two players?
• What is your own estimate, and how does it compare with the implied probability on the button?
• What is the margin? Add the implied probabilities, as in the table above, and compare markets.
• What happens to the bet if a player retires?

Betting on tennis with crypto

Crypto deposits and withdrawals are often faster than card or bank transfers, and fees are usually lower. Network fees still apply and vary by blockchain. Processing time also depends on confirmations and on the operator’s checks.

Price swings matter more with coins like Bitcoin or Ethereum, because the value of your balance can move between placing a bet and settling it. Stablecoins such as USDT and USDC are pegged to the US dollar, so many players use them for their balance. When you compare the best crypto bets, look at the odds and the margin first, because the payment method does not change either.

Bet within your limits

Decide your stake before you open the match and keep to it. Only stake money you can afford to lose. Odds describe a price, and they promise no result.
