Did you play last night?Why not (did you played last night)?Is there any reason can clear this to me? or:Did you play last night?Why not (did you play

Did you play last night?
Why not (did you played last night)?
Is there any reason can clear this to me?

or:Did you play last night?Why not (did you played last night)?Is there any reason can clear this to me?
