  1. Project Showcase
    This is an advanced version of the puzzle I posted a few weeks ago. I incorporated a few lessons learned from that project and also came up with a way to reduce the required accuracy. The solution is similar but I've added in complexity and a little decoy to throw the puzzler off the scent :)...

    This little puzzle was pretty fun to make and allowed me to use up some of the magnets from my last project. The goal of the puzzle is to remove the center piece from the tube. You will quickly notice that there isn't much to the puzzle - no buttons, latches or any other obvious locking...

    The goal of this puzzle is to make three cubes from the given pieces. Although this puzzle only has three pieces, the solution is pretty challenging - mainly due to magnet polarity. Super easy to build. See Build Instructions here: https://www.instructables.com/id/Three-Cube-Puzzle/ Solution:

    This is a fun little puzzle that goes by the name of Golf, Nine Hole and, my favorite, Gopher Hole Puzzle. The goal is to fit all six pieces into the box.

  8. Project Showcase
    This is my take on the classic wooden snake puzzle. Purchased ones generally range in size from 2" cubed down to key chain size. This one is 4.5" cubed. Although time-consuming and somewhat mind numbing, it wasn't very challenging to build. However, you will need to pay attention to the build...

  12. Project Showcase
    The goal of the puzzle is to fit the four T shaped blocks into the box, with the pieces flat. The box itself has two sides so there are two versions to fit the pieces. The first side has a larger area so it is pretty easy to fit all the pieces into the space. This side of the box has multiple...
  13. Project Showcase
    This puzzle will test your spatial ability and might challenge the way you think. You are given six pieces and asked to spell the letter "H". This task is pretty easy and should take less than 1 minute to figure out. Next, you hand your test subjects an additional piece with the same goal of...
  14. Project Showcase
    This is one of my favorite puzzles so far. You are given 8 blocks that must be placed in a box. They will fit and the box will be "totally filled." Once you are done, slide the lid on the top to complete the puzzle. Your test subjects might feel pretty smart by knowing that they solved this...
  15. Project Showcase
    This is my take on a classic rope and ring disentanglement puzzle. The goal is to separate the ring (the light colored one) from the puzzle strings. As with most disentanglement puzzles, the solution isn't intuitive. Can you figure it out from the pictures? If not, refer to the video for the...

With very little parts, it was really easy to make - less than 15 minutes. Go to the video for the solution if you cannot mentally figure it out from the pictures...
  20. Project Showcase
    This puzzle was dropped off on my desk last week. The “rocket” is placed in the cup. You must remove it without dumping it out or using tools (paper clips, tape, etc.). The problem is that there is no place to grab the rocket. How do you get it out? See video at the end if you can’t figure it...
