Because I like the smaller levels from the generator more than the big ones I saved the seeds for all levels of this kind I have found so far. As I remember most of them can be easily completed in 1-3 minutes. Here you can find the list of all 25 puzzles seeds and below are all of them with coresponding screenshots separated into five packs for better orientation within the long list.
