BoyleSports Sub Swap Review

BoyleSports Sub Swap is a new football betting feature that is available to all customers. Despite being one of the best football betting sites, they have been a little late to the party with this feature, but how does it stack up against substitute guarantees that are offered by their competitors?

In this sub swap review and guide you will find a full breakdown of how it works, the exact markets and leagues it covers and key rules and examples. we will also be providing proven strategies and tips on how it can be used to maximise your betting strategy.

What Is BoyleSports Sub Swap?

Sub Swap by BoyleSports is a substitution guarantee for bets placed on player-based football markets. this fantastic feature is perfect for betting on football, as it keeps your player bets alive when managers completely derail your plans by making changes during the game.

So if your selected player goes off, their replacement can still deliver the outcome you were hoping for when you initially placed the bet.

When you place a bet on any qualifying player market, which can be found further down this page, the bet wins if either:

• your original player, or
• the substitute who replaces them fulfill the bet

So if you back a player to be booked or to have a shot on target and they are substituted, your bet does not die. Instead it transfers to the incoming player when Sub Swap is active.

How BoyleSports Sub Swap Works – Step by Step

Using sub swap is pretty straight forward and can be done using the simple steps below.

1. Place a qualifying bet
   Pick a market with the green “S” Sub Swap icon.
   Example: Mo Salah to have 1+ Shot on Target.
2. Your player is subbed off before the market settles
   As soon as the player leaves the pitch, Sub Swap kicks in.
   Your bet automatically switches to the substitute who replaces them.
3. Bet can pass again if there is another substitution
   If that substitute is later taken off as well, the bet passes again to the next replacement.
   The bet can move through multiple players on that position chain during the match.
4. Outcome lands with any linked player
   If the outcome (goal, shot, assist, card, etc.) is delivered by any player in that chain, your original bet wins.
5. Bet settles at full time (90-minute result)
   Sub Swap applies to normal time only (90 minutes plus injury time).
   It does not include extra time or penalties.

Throughout this, your original selection stays visible in your betting slip, but the final player in the chain is treated as the one who finished the match for settlement purposes.

Where To Find Sub Swap – The Green “S” Icon

BoyleSports flags every eligible market with a green “S” icon:

• on match coupon pages
• inside your betslip
• in the My Bets section when Sub Swap is active

If there is no green “S”, the market does not carry Sub Swap.

You can even keep an eye on those bets using bet trackers, and if you don’t like your replacement you can cash out your bet early.

Key Rules and Terms You Need To Know

It’s worth noting that just like with most promotions there are key rules that apply to sub swap currently these are:

• No opt-in needed
  Sub Swap applies automatically when you bet on an eligible market.
• Pre-match and in-play
  Works on bets placed before kick-off and during the match.
• Applies to selected markets and competitions only
  Always check for the green “S” icon.
• Automatic switch to substitutes
  When your player goes off, the bet switches to the substitute.
  If that substitute later goes off, the bet passes to the next substitute in the chain.
• Multiple substitutes at the same time
  If more than one player comes on together, the player linked to your bet is determined using official match data.
• Cash out is not available on Sub Swap legs
  BoyleSports state that cash out is not available on Sub Swap legs at the moment.
• Winnings are paid in full as cash
  Winning bets that include Sub Swap are paid out in full as cash after settlement.
• 90-minute result only
  Sub Swap applies to normal time (90 minutes + injury time).
  It does not apply to extra time or penalties.
• Football only
  The feature is built for football player markets. Current documentation does not mention any other sports.

BoyleSports Sub Swap Example

We know sub swap is pretty straight forward, but we also appreciate that some people prefer visible examples of how it works. So here are two clear scenarios.

Example 1 – Anytime Goalscorer

• You back Isak to score anytime in a Premier League match.
• At 55 minutes, he is substituted.
• Ekitike comes on in his place.
• At 78 minutes, Ekitike scores.

Because Sub Swap is active:

• Your bet moved from Isak to Ekitike when the substitution happened.
• Ekitike’s goal means your Anytime Goalscorer bet wins.

Example 2 – To Be Booked

• You back Camavinga to be booked in a Real Madrid Champions League match.
• Camavinga plays 60 minutes without a card and is then substituted.
• He is replaced by Dani Ceballos.
• Ceballos is booked in the 88th minute.

With Sub Swap:

• Your booking bet passes from Camavinga to Ceballos.
• The card shown to Ceballos means the bet lands.

If Ceballos had got injured and also had to be substituted, the bet would pass again to the player that replaced him.

Why Use BoyleSports Sub Swap?

Sub Swap came about because of changes made to modern football matches, including the use of five substitutions and an increase in fixture congestion, So here are a few reasons we think you should take advantage:

• Keeps your bet alive
  Your bet remains in play even when your original player leaves the pitch.
• Reduces risk with rotation-heavy teams
  Clubs like Manchester City, Liverpool or Arsenal often make early or planned changes. Sub Swap gives you more cover.
• Fits player prop betting
  It supports shots, shots on target, assists, and cards, not just goal markets.
• Works in Bet Builders
  When a player bet carries Sub Swap inside a Bet Builder, it can save the whole builder if the substitute lands that leg.
• Pairs well with live betting
  Because it applies in-play betting, you can still bet during the match while knowing that your selection is backed by Sub Swap, provided the icon is present.

How Does Sub Swap Compare to Competitors

Many UK bookmakers now offer some form of substitution guarantee. BoyleSports’ Sub Swap competes with:

• Paddy Power Super Sub
• bet365 – Sub On, Play On
• William Hill Impact Sub

While each brand has its own pros and cons, we feel that BoyleSports stands out on:

• Breadth of markets
  Sub Swap covers goals, multi-goal lines, shots, shots on target, assists, and bookings.
• Multiple competitions
  It covers all major UK leagues plus big European competitions and UEFA tournaments.
• Automatic multi-sub chaining
  Your bet can pass from original player to first substitute, then to second substitute if needed, based on official match data.

From a our point of view, Sub Swap is one of the most flexible substitution features currently available in the UK market.

Tips for Using Sub Swap

You can treat Sub Swap as insurance on your player picks, but you can also build it into your betting strategy.

1. Focus on High-Impact Positions

Sub Swap works well on:

• Central forwards
• Wide forwards
• Attacking midfielders
• Aggressive full-backs or defensive midfielders (for cards and shots)

These are the players most likely to record goals, assists, shots, or bookings.

2. Consider Teams with Strong Benches

Sub Swap becomes more valuable when:

• The team has dangerous substitutes who often score or shoot.
• The manager regularly rotates the front line.

If you back a striker for a top side and he goes off, you might get a high-class substitute like a fresh striker or attacking winger in return.

3. Use Sub Swap in Bet Builders

For Bet Builders where one leg is a player stat, Sub Swap can:

• Reduce the chance of the builder losing purely because your player was subbed early.
• Give you extra comfort including player shots or cards bets.

Always check that the player bet shows the Sub Swap icon before you rely on it.

4. Target Competitions with Five Sub Rules

Sub Swap is more relevant in leagues and competitions where:

• Teams use five substitutions regularly.
• Managers rotate heavily due to fixture congestion.

The covered list includes the Premier League, Champions League, Europa League and more, where squad usage is high.
