INFINITE TETRIX is a Brainteaser with Unlimited Challenges

Lasercut from wood, two versions are available to tax your mind.

SOLO VERSION: Solve one of the preprinted challenges by placing all the polyominoes completely within the game board.
Visit www.TETRIX.fun to create endless challenges.

DUAL VERSION: Each player grabs polyominoes as needed and secretly fills their board completely to make a challenge for their opponent
Both players dump out their boards and scatter the pieces in front of the opposing player.
Players now quickly assemble their new challenge – speed counts!
The first player to complete their board is the winner.
Note: If only one person, play the SOLO version above.

WORDSY VERSION: Wordsearch in a box. Use clear acrylic shapes to mark 8 or 9 words. Print unlimited challenges.

MAGNETIC VERSION: Solo version for use by bedridden hospital patients. 7x7 inches, 20 shapes.
Two versions: ready to use or assembly required (save $4).

MAGNETIC TRAVEL VERSIONS: Solo magnetic pieces in 3x3 tin. Play challenges on the bottom of the tin.
One version requires you or your kids to peel and stick magnets - save $4 with do-it-yourself.

TINY TETRIS: Solo game in a 2x2-inch plastic cube.

Travel-friendly, especially the DUO version for kids playing together in cars and planes.

This is my new favorite puzzle, so much fun to do!! It is clearly handmade, with beautiful colors, and clever cutting, including hints. The five layers added a wonderful level of challenge. It is so much better than I thought it would be. Mark is wonderful at communicating as well, and even offered me a couple of extra choices. I highly recommend this!

This Seller was great to work with!! I explained the set of cards was for my adult brother who is recovering from a brain injury. I mentioned that he raises sheep on a small farm. The Seller customized a set based on my comments-which he did not have to do! I’ve seen the cards through zoom and they appear to be of great quality. Delivery was as promised.

I basically got these to bump up my order to get the free shipping, but I use these way more than I expected. They make perfect life counters for MTG. They are easy to use, compact and look really good.
