If you’ve tried our Math Square challenges, here’s something new to the Brain Game that you might also enjoy: a number block puzzle.

Each of the nine squares inside the main red grid should contain either a 1, 2, or 3. Three of these numbers are already provided for you. Place the number 1, 2, or 3 in each of the blank squares so that the sum of the rows, columns, and diagonals equal the totals shown at the ends of those lines (at the equal signs). Good luck!

  3. My dad excels at these puzzles (any number between 1-9), so I’m glad this was restricted to numbers between 1-3….I feel like I’m on his level, even for a day!

  10. I love the math squares. This was a nice twist on that.. The diagonal numbers defiantly made this one go quick.

  11. Gotta agree with you, Melissa – those diagonals were certainly defiant! ;)

    But seriously, I’m a major Sudoku fan, so I love this kind of thing.

  12. The 12 made it kind of easy, but I really liked this style of puzzle. You’re on to something. I assume it would be harder if you added one more possible number for each square (i.e. 1,2,3, or 4). Maybe there would just be too many options that way.
