- Using multiple names in a single tournament
- Intentionally losing any matches in favour of the opponent
- A player facing any unfair behaviour from other players should reject playing them further. Continuing playing such players is considered as unsportsmanlike itself. (in challenge mode only)
- Using a computer or any kind of assistance to decide your moves in a board game, is strictly prohibited in all tournaments.

Umpires (moderators) have the right to warn or disqualify any player whose behaviour reminds them of any of the above, or for any conduct by a player which in the opinion of the umpire is wilfully or persistently unfair.
