A pack with 18 different puzzles with random images with no real theme connecting them which for the most part make for good jigsaw puzzles. All the jigsaws however have normal, traditionally jigsaw shaped pieces which I personally much prefer compared to the weird ones you sometimes get with this game. Should honestly just be a setting in the base game to have these kinds of pieces only.
The are on the medium side of things when it comes to amount of pieces (between 140 and 640 pieces, average of 322 pieces).
