The IQ Deluxe Square is no ordinary puzzle game. Sure, the board is square, but that’s the only thing simple about it!

Your mission is to fit every hollow puzzle piece perfectly into place, and with raised edges on the board, there’s no room for error.

Every colourful piece has to sit in the space just right, making the challenge all the more addictive!

With 120 puzzles to tackle, ranging from easier warm-ups to brain-bending tests, you’ll always have a reason to keep coming back for more.

It’s clever, compact, and designed to get your brain buzzing. Perfect for teenagers, adults, or anyone who loves the thrill of solving something tricky.  

This elegant game set comes complete with a square board and lid, 10 hollow puzzle pieces, and a handy booklet filled with challenges and solutions.

It’s rated 4 out of 5 for difficulty, so expect plenty of "aha!" moments along the way.  

  • Raised edges on the board mean pieces must fit exactly  
  • Includes 120 puzzles with solutions to check your progress  
  • A high-quality solo logic game for ages 14 and up   

Give the IQ Deluxe Square as a gift or keep it for yourself - either way, you’re in for hours of smart, satisfying fun!
