What is in a Lucky 31

31 bets on 5 selections:

Part of the bet	Bets
Singles	5
Doubles	10
Trebles	10
4-folds	5
5-fold accumulator	1
Total	31

It is the five-selection version of the Lucky 15. The cost climbs fast: £1 a line is £31, or £62 each way.

How the return is worked out

Each line is settled on its own: the line stake times the decimal odds of every selection in it, multiplied together. A losing selection makes every line it is in return nothing. A void selection counts as odds of 1.0. For each way bets the place part uses place odds: (decimal odds − 1) × place fraction + 1.

line return = stake × odds₁ × odds₂ × … and total return = sum of all line returns

Worked example

£1 a line: A at 2/1 (won), B at 9/4 (won), C at 3/1 (lost), D at 6/4 (won), E at 4/1 (lost). Total stake £31.00.

Line that pays	Part	Returns
A	Win	£3.00
B	Win	£3.25
D	Win	£2.50
A + B	Win	£9.75
A + D	Win	£7.50
B + D	Win	£8.13
A + B + D	Win	£24.38
Total return		£58.50
Profit		£27.50

Not included: rule 4 deductions, dead heats, each way extra places and bookmaker bonuses (for example double odds on a single winner). Your bookmaker's settlement is final.
