There are certain elements I can include that makes the challenge significantly harder. In my Traffic Light Simulator, I can either make the roads all be the same length (easier), or a different length (harder). In my Mafia challenge, I can only include the standard 4 roles in a 7 player game, or allow variations of roles (including role-changers) and variable number of players.
I want the best of both worlds: Make it easy to participate, but also give a challenge for those so inclined. In both of these cases, a submission to the more difficult challenge is competitive in the easier challenge (ignoring any differences in input).
What am I allowed to do?
Can I have multiple competitions in the same post (Two different scoreboards)?
Can I post the easier challenge, and then the more difficult challenge (even though the easier one is a duplicate of the difficult one, but not vice versa)?
Or, do I simply have to pick one of the variants?
