What is a Patent bet?
A Patent is a full-cover bet on three selections with 7 bets: 3 singles, 3 doubles and 1 treble. It is a Trixie with the three singles added, so one winner is enough for a return.
A £1 Patent costs £7; each way it is 14 bets and costs £14.
Using the calculator
Pick Per bet to type the unit stake (what most betting slips ask for), or Total to type what you want to spend and let the calculator split it. An each way bet is two bets per line, so it costs double.
Mark each selection as Won, Placed (each way only), Lost or Void. A void (non-runner) is settled at odds of 1.0, so the bet carries on as a smaller bet. Open Rule 4 / dead heat on a row to apply a deduction or a dead heat to that selection.
