Boylesports Sub Swap keeps your bet alive even if the player you have backed is substituted during the match. If your selected player comes off, your bet automatically transfers to the player who replaces them — and if that substitute is also taken off, the bet passes on again.
It applies to singles, multiples, and bet builders across a wide range of player markets and competitions.

What is BOYLE Sports Sub Swap?
Sub Swap is Boylesports’ version of the Super Sub feature offered by bet365, Sky Bet, and Paddy Power. The core mechanic is the same across all bookmakers: if you back a player in a qualifying market and they are substituted before the market settles, your bet rolls onto the player who comes on in their place rather than being settled as a loser.
The feature addresses one of the most frustrating outcomes in bet builder and player market betting — the early substitution. If you bet on a player and they’re substituted, the bet would normally be a loser. Sub Swap removes that outcome entirely for qualifying markets.
You do not need to opt in to Sub Swap. It activates automatically when the Sub Swap icon is visible on the market you are betting on. Look for the icon on the match page or in your betslip before confirming your bet.
Sub Swap is available online and in retail shops over the counter. It is not available on Self-Service Betting Terminals (SSBTs) in-store.
How Boylesports Sub Swap Works — Step by Step
- Navigate to a match displaying the Sub Swap icon on the Boylesports app or website
- Select a qualifying player market — for example, Erling Haaland to have 1+ shot on target
- Add to your betslip, either as a single, multiple, or as a leg in a bet builder
- Confirm your bet — Sub Swap is automatically applied, no opt-in required
- If your selected player is substituted before the market settles, the bet transfers to the substitute
- If the substitute is later also substituted, the bet passes on again to the next replacement
- Your bet settles based on the final player’s performance in 90 minutes of normal time
Practical example: You back Erling Haaland to score anytime for Manchester City. Haaland doesn’t score and is substituted in the 60th minute for Omar Marmoush. Under Sub Swap, your bet transfers to Marmoush to score anytime. Marmoush is then substituted for Oscar Bobb. Your bet passes again to Bobb. If Bobb scores before the final whistle, your bet wins. The original player — Haaland — still shows in your betslip, with the final player appearing as the active selection.
Which Markets Does Sub Swap Cover?
Sub Swap applies to the following player-based markets at Boylesports:
- First Goalscorer
- Last Goalscorer
- Anytime Goalscorer
- To Score 2+ Goals
- To Score 3+ Goals
- Next Goalscorer
- To Assist
- Player Shots
- Player Shots on Target
- To Be Booked
These markets can be backed as singles, as part of a multiple, or as individual legs within a bet builder. Sub Swap is particularly valuable in bet builders where a substituted player leg would previously have killed the entire bet — with Sub Swap active, that leg carries on regardless.
Which Competitions Are Covered?
Sub Swap is available on the following competitions at Boylesports:
England: Premier League, Championship, League One, League Two, FA Cup, League Cup
Scotland: Scottish Premiership
Europe: Champions League, Europa League, UEFA Conference League
Other Domestic: Spanish La Liga, Italian Serie A, French Ligue 1, German Bundesliga, Netherlands Eredivisie, Portuguese Primeira Liga
Ireland: Irish Premier League
In practice, the vast majority of matches you would build a bet builder around — Premier League, Champions League, La Liga, Bundesliga, Serie A — are covered. The Sub Swap icon will confirm it is active on a specific match before you place your bet.
Sub Swap and the Bet Builder Boost — Using Both Together
The most effective way to use Sub Swap is in combination with the Boylesports Bet Builder Boost. On featured fixtures each week, Boylesports offer a 25% boost on winning bet builder returns (rising to 50% on standout matches). Sub Swap and the Bet Builder Boost can be active on the same bet simultaneously.
This means you can build a bet builder on a featured fixture with player legs covered by Sub Swap and the overall bet boosted by 25% or 50% on top. A £20 bet builder with player shots, a goalscorer, and a cards market — all Sub Swap-protected — returned at odds of 6/1 with a 25% boost would pay £170 instead of £140.

Sub Swap vs Super Sub — How Boylesports Compares
Sub Swap is Boylesports’ name for a feature that several major bookmakers offer under different names:
| Bookmaker | Feature Name | Competitions | Markets |
|---|---|---|---|
| Boylesports | Sub Swap | PL, CL, La Liga + 11 more | 9 player markets |
| bet365 | Super Sub | PL, CL, La Liga + more | Goalscorer, shots, assists, bookings |
| Sky Bet | Super Sub | PL, CL + selected | Goalscorer markets |
| Paddy Power | Super Sub | PL, CL + selected | Goalscorer markets |
Boylesports’ implementation covers a competitive range of competitions and a broad set of markets, including the booking market, which not all competitors include. The automatic activation — no opt-in required — is a practical advantage over some rivals, where the feature requires a manual toggle in the betslip.
