Number Choosing Contest.

You are not necessarily correct.

In either case, my suspect rule 4 is probably wrong. It feels too simple.

The following numbers should follow rules 1, 2, 3, and 5.

These should confirm whether I am correct about rule 4.

631

2269

5419

9241

33391 (follows all rules if I am correct)

Edit: Oh, as it turns out I miswrote my rule 4 :v

I'll still submit these.
