A Patent consists of 7 possible bet combinations involving selections in 3 different events.
The bet includes 3 doubles, 3 singles and 1 treble.
A single is a selection of just 1 event, a double is a combination of 2 events and treble is a combination of 3 events.
 
E.g You place a patent bet on games A,B and C.
Let's say your stake is N50, please note that your total stake will be 50 X 7 = 350
This is so because your stake is charged separately for each possible combination and winnings are credited for each correct combination as well.
 
Your combinations would be arranged thus:
3 singles
A X 50 = Winnings
B X 50 = Winnings
C X 50 = Winnings
 
3 doubles
A*B X 50 = Winnings 
A*C X 50 = Winnings
B*C X 50 = Winnings
 
1 Treble
A*B*C X 50 = Winnings
Just one successful selection guarantees a return.
