Good evening, Kendo.
I hope this finds you well.
The three "missing" clues produce an answer which is the game Myops is playing with us and them.
I
1d. is, to me, really obscure. It's an old form of cricket, a compound word made of something you sit on, plus an integral part of many sports.......
2d. is where you "go out" to have fun. The answer is also the name of a musical film which starred Gene Kelly and Frank Sinatra.
Hoping this helps!
