It can be surprising to see how hard some people find this. Even some native speakers.
Those of us who have played before should probably stay out of this at least initially. We know who we are.
Each move in this game has to be an animal which is also a verb if you put "to" in front of it. It's permitted to make moves which require prepositions after them in actual use. Other than the most obvious cases it might be best to give an example and/or say what it means. This game can also be played in Italian and while there are more moves than you might expect my suspicion is that there are a lot more in English. Of course in the Italian version you have to add "-are", "-ere" or "-ire" to the animal and may need to change the spelling in small reasonable ways.
I'll start with perhaps the two most boring moves as examples. No explanations or examples needed for these, I hope.
