You begin by picking the animal puzzle and whether you'd like it to be an easy or advanced.
And then they just drag the pieces over to the puzzle tray. When they drop a piece into the proper place is makes a clicking noise. If it is placed in the incorrect place then there is no audible response and the piece continues to look out of place.
In easy mode there are fewer pieces.
To make any puzzle less complicated click the grid button. This shows the shapes of each piece in a faint outline.
Hope you enjoy and Happy Puzzling!
