Easy jigsaw puzzles
12 pieces is a few minutes. 24 is still a short sit. The cut is the same cardboard interlocking — just a smaller die.
When to move up
48 is the daily Casual track. If 24 feels like nothing, that is the next door. 192 is a weekend, not a warm-up.
Hints
Ghost photo and outline are optional. Turn them on for a first easy table. Turn them off when you are bored.
