I thought I'd share this here in case anyone was looking for a quick/easy review game that takes up most of the class.
It does use a paid version of Kahoot, so I don't think it can be duplicated/edited without that, but you can play it as is without an account.
It contains a couple questions per grammar point (with a heavy focus on present perfect/present perfect continuous since a lot of my students really struggled there) and a little bit of vocabulary thrown between grammar questions to break them up a little.
On questions a good chunk of the students found difficult and got wrong, pause and go over the grammar and why the ones they chose would not be the correct one.
There are a lot of questions in the quiz, so you might end up having to skip the last few if it's running a little longer than you expected. It really depends on the class and how long you need to spend discussing grammar they struggled with.
Here is the link to the Kahoot:

How many players can play in this game?
@claireeee It says on Kahoot when you launch the game, "Play with up to 2000 players".
