For educators, they are terrific classroom tools, particularly when the demonstration board with its enlarged, laminated instruction booklet containing the first preset 101 problems is employed to show the children how to proceed in order to enhance the skills mentioned above. This also comes with two sets of game pieces in case one or more gets misplaced.

The demonstration board also attracts attention in toy stores and the like, particularly as we supply posters to stores showing all the awards which have been won.

The LONPOS 101 and the LONPOS 303 Pyramid and Rectangle games are pocket/ purse sized making them perfect travel games or for working on while waiting in a doctor’ s office, etc.

LONPOS 101 has 76 preset rectangle problems and 25 preset pyramid problems to solve, ranging from very easy to very difficult.

To play 2D games, take out the 12 colorful game pieces (known as pentominoes) from the box and put them on the tray. Then, from the booklet, locate a problem that you would like to try to solve and place the pieces on the game board in accordance with the illustration. Once you have done that, the challenge is to fit the remaining pieces into the spaces remaining.

To play 3D games, take the pentominoes out of the box, close the box and turn it over so that the game board is facing upward. Locate the problems in the booklet, set up the pyramid in accordance with the illustration and then fit the remaining pieces into place to complete the pyramid.

Sounds easy? The first few problems really are, but as you work through the more difficult problems you will find some to be excruciatingly hard. By this time you are probably addicted and will not want to put the game away until you have solved the problem!

While our recommended age level is for 8 year olds and up to adults (ALL age groups love these games – several hundred were purchased as goody-bag gifts at an international conference of rocket scientists, who were enthralled), even children as young as four enjoy doing the easier problems under adult supervision.

They comply with European safety standards CE / En71 so there is no lead and no phthalates.
