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.

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.

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

All around wonderful puzzle. 5 stars on every level. They are so beautifully made, the kind of thing that looks great on the coffee table inviting any and all to play. We all need to play more! Any of these would make a great gift. Arrived on time.

I thought this would be great (fairly easy) for my 93 year old, bedridden mom and tried it upon arrival, after a few hours I had to look up a hint to get started so these are serious puzzles for serious puzzlers(IMHO). I should've ordered the magnetic variety to avoid pieces getting lost in the bedding when they get knocked off the bed tray table. The way the puzzles are made appeals to the senses, they feel good and they sound good- no plastics clicking together kind of thing and look good. I'm ordering the symbols one next.

I bought two puzzles for mother's day, one for each of my sister-in-laws. They loved them. Both gave rave reviews. First they really liked the personalized composition. Second the hex meandering was fun and different. Third and best of all, the hex confused my brothers. Fun gift. -Had some trouble with shipping, but COVID is the culprit interfering with most of the issues and delay. -Owner Mark was great and very responsive to questions and assistance. I'd work with him again and love the product. Order early in this environment.
