b. placing est-ce que (qu') before the statement.

2. With the pronoun "je," only the "est-ce que" form is used. (the sound of "joue-je" is UGLY/moche!)

Sure! Here are the negative and negative interrogative forms of regular -er verbs in the present tense:

NEGATIVE FORMS:
I do not play - je ne joue pas
You do not play - tu ne joues pas
He/She/One does not play - il/elle/on ne joue pas
We do not play - nous ne jouons pas
You do not play - vous ne jouez pas
They do not play - ils/elles ne jouent pas

NEGATIVE INTERROGATIVE FORMS:
Am I not playing? - est-ce que je ne joue pas?
Do you not play? - est-ce que tu ne joues pas?
Does he/she/one not play? - est-ce qu'il/elle/on ne joue pas?
Do we not play? - est-ce que nous ne jouons pas?
Do you not play? - est-ce que vous ne jouez pas?
Do they not play? - est-ce qu'ils/elles ne jouent pas?

To form the negative form, simply add "ne" before the conjugated verb and "pas" after it. To form the negative interrogative form, the word order remains the same as in the affirmative interrogative forms, but "ne" and "pas" are placed around the verb.

Please note that these forms are applicable to regular -er verbs.
