I hope some of you find this kahoot useful.
My students seemed to have a lot of fun
It should take about 35 or 40 minutes to complete so it would be pertinent to leave a little bit of time for set up and getting students prepared.

I like this, this is thorough and concise.
I do have a few suggestions:
I feel like 30 seconds is "too long", I usually put 20s and try to write small sentences. If you finish faster/sooner, you can then comment/explain more the questions with the most mistakes.
I also usually put 3 answers and then move to 4 as a way to increase the difficulty.
Then again, I don't make multiple units summaries, always quick reviews of a particular grammar point or vocabulary reviews.
Feel free to use these suggestions or ignore them.
Keep up the good work!! :)
