Includes a Shuffle puzzle and Block Jigsaw.With Shuffle you must arrange the squares into the correct sequence. Seems easy but gets difficult near the end. Ten array sizes and three square styles should suit all levels. Block Jigsaw allows you to take any suitable bitmap for the Block Jigsaw picture. For the young, two variations on Block Jigsaw are provided. To see the completed block jigsaw just click the R.H mouse button. The first is an Alphabet Block Jigsaw. You drag the letters to their correct positions, great for kids starting to learn their alphabet. The second variation is a number version.
