The "Free Hit" chip sits alongside the Wildcard, the Triple Captain and Bench Boost in Fantasy Premier League.
A Free Hit allows for unlimited transfers in a single Gameweek.
It can usually only be taken once a season, but in 2021/22 a second Free Hit has been provided.
Managers can replace their entire squad for that Gameweek BUT their 15-man line-up is returned to how it was at the start of the Gameweek for the next deadline.
Please note that, in 2021/22, if you have two Free Hit chips you will be unable to play them in consecutive Gameweeks.
If the Free Hit chip is played leading up to Gameweek 10, for example, once the deadline has passed you will see the points scored by your new Free Hit squad in the "Points" tab.
But in your "My Team" and "Transfers" tabs, your old Gameweek 9 squad will have returned.
Like the Wildcard, the Free Hit is used when confirming transfers. It cannot be cancelled once confirmed.
Be aware that when playing your Free Hit chip, any free transfers carried over from previous Gameweeks will be lost. You will be back to the usual one free transfer for the following Gameweek.
Also, if you use your free transfer and then subsequently decide to play the Free Hit chip, you will lose the initial signing you made.
On the flip side, managers who take points hits and then regret the decision can use the Free Hit to cancel those deductions.
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.
So if a player has suffered a price drop while your Free Hit chip was active, you will have lost value on that player.
While the Free Hit cannot be used to play the market, it is nonetheless a powerful strategy.
It 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, or when postponed fixtures cause issues.
The Free Hit chip lets managers pick players who are not only in action but also have good fixtures.
It also allows managers to rethink their approach to Double Gameweeks, where teams have more than one fixture in a single Gameweek.
These nearly always take place in the second half of the season and have always proved popular windows in which to put chips in play.
The Free Hit can be used to maximise the number of players in a squad who will play twice.
That can lead to many FPL managers rethinking their use of existing chips, particularly the second Wildcard.
One of the most powerful aspects of the Free Hit chip is the ability to take advantage of differentials.
Normally, when using their free transfers, managers buy players who can deliver returns over a number of Gameweeks.
But the Free Hit chip allows them to focus on short-term gains, targeting players with the potential for big points in that specific Gameweek.
Finding these one-off differentials could be key for a manager looking to gain an advantage over mini-league rivals.
