The kit comes with 30 puzzles geared for beginners. The player begins with card #1 and steadily works through the puzzles in numerical order. They start off very easy so that young children do not get discouraged. These beginning cards actually show you which pieces to use in the puzzle.
Then, each one gets a little bit harder than the last, until finally you have a really challenging one that may involve all the pieces.
Some of the harder puzzles are also layered.
But I love how once my daughter discovered this, she now sometimes adds her own decorative touches and places extra pieces on the top to personalize her piece.
