Thinking is fun!

Who thinks mathematics can be educational AND fun? We do!

The creators and team at NUMBRCISE™ invite you to test your ingenuity with mental stimulators that are laid out like crossword puzzles but the twist is, no words or phrases are given as clues. In our world, numbers rule.

To play, you must fill in all the blank squares in the grid with numbers ranging from 1 to 9 in order to find a synchronized solution to a series of horizontal and vertical equations – all at once. Each week, we will release two puzzles exclusively on The “easy” puzzle goes live on Mondays and the “medium” brainteaser will be posted on Fridays. The solution to each will be uploaded to the site on Wednesdays and Sundays, respectively.

Expect a rush each time you solve one of our puzzles and a sense of sweet satisfaction from getting the last clue.
