Subject: Enforce more than one dot in Galaxies puzzles.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=f9027226a05b6e2fc49d0256262edc6cc3a8c569;p=sgt-puzzles.git

Enforce more than one dot in Galaxies puzzles.

At minimum size (3x3) Galaxies can generate a pre-solved single dot
game.

You have to add and remove a line to get the victory flash which is a
bit weird, so just prevent this.
