Yeah, it's actually a pretty easy one this week. It's sort of like Sudoku. Have you ever tried a Sudoku puzzle? They're really fun!


Has anyone tried to solve this weeks math puzzle (Magic 8 Cube)? I haven't yet, but it looks cool!
Yay! I think I solved all four of the math puzzles for this week (Magic 8 Cubes)! Has anyone else tried them yet? They're REALLY fun! Rather like Suduko again. Give them a try! =D
Okay, so I checked my answers to the solution to last weeks puzzle (Magic 8 Cubes) and it says that I got C. wrong. I don't understand what they mean. Here is the instruction:
C. Arrange the numbers 1-12 on the edges so that faces and parallel edges have magic sum 26.
I did that! In fact, it seems as if they didn't count the top square or bottom square as a "face". Their bottom square has the sum of 13 and their top square has the sum of 39. All of my faces (including the top and bottom squares) have the sum of 26. What am I missing? Please help!!!

Okay, this week the puzzle is Knots. Any thoughts? I'm going to guess that the one on the left is the unknot and the one on the right is the trefoil knot. (?)
