If you guess you lose, the game doesn't guarantee no guess boards, it generates regular boards and then punishes guessing in the post-game review phase.
The game expands the previous board by using the reveal order as a seed to produce the next expansion.
If you get stuck use the tree on the side to try a different reveal order, you can go from any branch to any branch.
If you want you can contribute a map generator, or if you have any other suggestions/requests feel free to say.
