Moraff's Jiggler 3D is a fun concentration and memory puzzle. Choose from a selection of attractive photos to turn into puzzles with rectangular 3D pieces which you must move to the correct position. Click on one block and then on another to make them trade places. When a block is in the correct place it will stay there (you can not move it again). The object is to reconstruct the original photo. There is help available by examining the original photo in a preview pane. You can define the number of blocks on the board in six steps from 4x4 to 20x20. Click on any pair to make them change places; once a piece is properly positioned, it can't be moved. This is a visually challenging game for adults with a great 3D look and easy for children to play. It can be as simple or as complicated as you like. Play the game in full-screen or windowed modes. MIDI-based background music and quality sound effects accompany your play (but can be turned off if desired). Several other options are available.
