Hi EGM-Perpete,
In my opinion:
A game is rigged when two players agrees the roster or the enthusiasm to be played before the game, knowing that this would benefit both players.
I am interested in the part where a player asks to rig the game and the other refuses the offer and would like to report but doesn't know if this offer of rigging a game is against the rules.
I hope I made myself clear.
Thanks for your comments
Best
