What is a Patent bet?
A Patent is seven bets on three selections: three singles, three doubles and a treble — a Trixie with the singles added. €1 a bet costs €7, or €14 each way.
The singles mean one winner is enough for a return, which suits three selections at bigger prices: a 4/1 winner alone pays €5 back on a €7 Patent, while two winners add their double and three add every double and the treble.
| Bet | How many |
|---|---|
| Singles | 3 |
| Doubles | 3 |
| Treble | 1 |
| Total | 7 |
How much does a Patent pay? A worked example
One winner of three, €1 a bet: 4/1 (5.00, won), 3/1 (4.00, lost), 9/2 (5.50, lost). The Patent costs €7.00 and returns €5.00 — a loss of €2.00. The figures above are the calculator's own: change any price or result to see how the return moves.
Football selections
These bets started on the racecourse but settle the same on football: a selection is any call at its price — a result, over 2.5 goals, both teams to score, an outright. Every leg carries the bookmaker's margin, and multiples multiply it, so the margin calculator is worth a look before you choose prices, and our match predictions put the model's calls beside the bookmaker's prices — the day's Free Picks open to everyone. For one straight multiple, use the accumulator calculator.
