How can I sequentially lay a multi?

Sequential laying is a technique used with multi promos that offer a refund if one leg fails, or with multi boosts. Rather than laying all legs at once, you wait for each game to finish before laying the next one. This allows the calculator to adjust your recommended lay stake at each step based on what has already happened.

Our Multi Promo calculator handles all the maths for you. Select the number of legs at the top (3, 4, or 5) then fill in the Settings section.

Settings

• Stake: Your total multi stake at the bookmaker.
• Multi Odds: The combined odds of your multi.
• Commission: Your Betfair commission rate for the relevant market.
• Method: Lock-in or No-loss (explained below).
• Bonus: The value of the refund if one leg loses. Leave at 0.00 for odds boost promos.
• Retention: The expected conversion rate of the bonus. Use 100% for cash refunds and around 70-80% for bonus bets.

Placing your lays

The Selections section shows a row for each leg. Enter the lay odds from Betfair and the calculator will suggest a lay stake. The suggested amount is designed to leave you at break-even if the multi loses at that leg.

You can choose to lay less than the suggested amount to take a small loss at that stage in exchange for a better position on the final leg. Once you enter your actual lay amount the calculator updates its suggestion for the next leg automatically.

Lock-in vs No-loss

On the final leg you have two options:

• Lock-in: Your profit is the same regardless of whether the final leg wins or loses. This gives you a guaranteed return before the last game starts.
• No-loss: You break even if the final leg loses but make a larger profit if it wins. This carries slightly more variance but has a higher upside.

Before you start

Make sure your selected games do not overlap. You need enough time between each result to place your next lay before the following game starts. Odds can also move between the time you place your back bet and when you are ready to lay each leg, so there is some variance involved in these promos.
