The "Free Hit" chip sits alongside the Wildcard, the Triple Captain and Bench Boost in Fantasy Premier League.
A Free Hit can be taken once per season and allows for unlimited transfers in a single Gameweek.
Managers can replace their entire squad for that Gameweek but their 15-man squad of the Gameweek before returns for the next deadline.
For example, if the Free Hit chip is played leading up to Gameweek 2, once the deadline has passed, you will see the points scored by your new squad via the points tab.
Your previous squad will now return and is accessible on the transfers tab.
Like the Wildcard, the Free Hit is used when confirming transfers. It cannot be cancelled once confirmed.
Managers cannot benefit from any price changes gained from their new Free Hit squad.
However, price changes applied to their previous line-up will take effect on their return once the chip expires.
While the Free Hit cannot be used to play the market, it is nonetheless a powerful strategy.
If offers an alternative to the Wildcard as a way of temporarily fixing a squad.
FPL managers can turn to the Free Hit when injuries and suspensions hit and try to ride them out.
The chip can also be used to patch up squads when postponed fixtures cause issues.
For example, if there are just a few PL fixtures after postponements due to FA Cup ties, the Free Hit chip lets managers tailor their squads to those teams playing, reverting to their previous line-up for the next Gameweek.
It also allows managers to rethink their approach to Double Gameweeks, where teams have more than one fixture in a single Gameweek.
These have always proved popular windows to put chips in play.
The Free Hit can be used to maximise the number of players in a squad with the prospect of two fixtures in a Gameweek.
That can lead to many FPL managers rethinking their use of existing chips, particularly the second Wildcard.
