Monster Party 100-Piece Decoder Puzzle

I bought this for my niece's birthday and ended up sitting down to do it with her. The 100 pieces are just the right size for little hands, and the secret hidden objects kept her guessing well past her usual attention span.

The decoder aspect makes it way more fun than a standard puzzle — my kid actually used the hidden-object clue to hunt for pieces instead of just zoning out. It took us a few evenings across the week, and the monster party theme kept her asking to do "one more round" each time.

My 6-year-old finished this in one sitting and immediately wanted to redo it to find every hidden object again. The pieces are sturdy and the decoder element adds a fun twist that keeps them engaged long after the puzzle is done.
