On Line Puzzle Index . We have created and added these free, interactive, on-line Puzzles for your use. This is even more noticeable on black and white graphics but does not affect the pleasure of doing the puzzle.
Computers are smart.
When you do return to a page anywhere, the loading speed is significantly reduced. Pathway memory is a good thing. Puzzle pieces tend to 'hide' under the menu in the upper left corner. Place your cursor on the top of the menu box, just as you would any puzzle piece, and move it somewhere else. This is currently a free service.
