A Lucky 63 puts six selections into every possible combination, from individual singles to a sixfold. Our free Lucky 63 calculator works through that list using the odds, stake and outcomes you enter. Whether you're checking a completed slip or comparing possible results from our online sports betting markets, it helps show how the individual bets contribute to the total.

Work from the prices on your bet receipt when checking an existing wager. Give each of the six picks a row, then read its price alongside the result you've selected. If the odds are similar, adding a name in the notes field makes the entries easier to check against the slip.

For prices written as fractions, 7/2 goes into the two boxes as seven followed by two. The odds-format selection also lets you work with decimals, so set it to match your receipt before copying the figures.

Look at the outcomes before relying on the total. A row left on Winner contributes a winning result to the calculation, even if that pick actually lost. For a completed bet, supply the settled results and stake from your receipt. The tool works from those entries rather than choosing winners or reading your account.

Six picks generate 63 separate bets. Here's how they're grouped in a win-only Lucky 63:

Read down from the singles and the combinations grow: all six picks are backed individually, then each possible pairing becomes a double. The same pattern continues through the larger combinations until all six join the sixfold.

That is different from placing only a sixfold accumulator. A Lucky 63 includes the smaller bets as well, so its total doesn't depend entirely on the sixfold succeeding.

The amount staked on one combination is the unit stake. It is repeated across the 63 bets, rather than shared between them. A win-only Lucky 63 at 10p per bet therefore costs £6.30 overall.

An each-way version has 63 win parts and 63 place parts. Using 10p for every part therefore brings the outlay to £12.60. It's that full amount you'll need to compare with your spending limit before confirming a wager.

For a straightforward win-only calculation, each successful single or multiple is worked out separately. Multiply the decimal odds within a winning combination, then multiply that figure by the unit stake on it. Decimal prices include the returned stake, so don't add it again afterwards.

With the successful singles and multiples worked out, their combined returns give the overall amount. The bet breakdown in the calculator groups the results so you can follow what's contributed.

Label three winning selections A, B and C, with the remaining picks all losing and no settlement adjustments. Alongside the three winning singles, the successful doubles are AB, AC and BC, with ABC forming the winning treble. Their combined return still needs comparing with the total stake across all 63 bets; a return doesn't necessarily cover that cost.

For an each-way Lucky 63, enter the applicable place terms as well as the prices and results. A horse that finishes in a paid place without winning can contribute to the place combinations while its win combinations lose.

A withdrawn selection needs the outcome specified by the market's rules. Where it's void, its single stake is normally returned and multiples carry on without that leg. Ante-post non-runner terms can differ.

Use Show Rule 4 for an applicable deduction, copying the actual adjustment recorded for the bet. Bonuses and concessions need their own qualifying terms checked too. Don't assume that a standard calculator total includes an enhancement unless it has been expressly accounted for.
