This is the new TETRA-TEN Puzzle and playful sculpture

10 Colorful Pieces...3 years to adults love to manipulate this into creative forms



Solve this Challenging 20 piece puzzle by forming a 4-sided pyramid, a tetragon.

TETRA Puzzle natural wood finish

The natural finish woodgrain version of TETRA is easy to manipulate into different sculptural forms but difficult to form into a Tetragon.  It comes as 20 attached balls in a single plane. You solve it by turning balls and/or folding balls until the 3 dimensional tetragon shape is formed. Difficult enough as that is, the balls can be detached from each other and then attempt to reform the tetra by re-attaching. This last way of solving is extremely difficult and may not be successful unless the balls are attached in just the right sequence. Probably the most difficult 3-D puzzle anywhere.

Tree Ballinko balancing game package

A family game, easy to play --another new toy for 5 years and up. The goal is to use all 36 balls and have the "tree" remain standing. As players add balls ("limbs and leaves") a loss of balance will topple the tree. The game plays until all are added and the tree is balanced. This game, made in USA, can be played cooperatively--where everyone wins when the tree is balanced; or it can be a competitive challenge where the top score wins. (each colored ball has a value). Either way, it's fun to play.
