Sometimes maps are obviously unfair, non-competitive, or would not be fun to play.
To solve this problem, allow a majority of players the opportunity to veto the map (or at least give room owners setting to enable).
If enabled, once the game starts on non-tutorial board, non-bot players are able to see the board, but do not yet know the order of play. They have 20 seconds to accept or veto the board. If a majority of non-bot players veto the board, a new random board is generated and the process repeats. If at least 50% accept or do not respond, the board is accepted and the game begins.
The solves the problem with minimum time wasted for players.
