Logic Problem #1

Every ten entries, I will have a logic problem for you to solve. Each problem will have four categories, four items per category, and 3 to 8 clues on solving the puzzle. I’ve been doing several logic problems while on break. Inspired by what I do, I make some too. Normally, I would give out a grid, but you may have to set it up based on the clues and stuff. Some logic problems would be Animal Crossing related, but others would not.

Setting up a Logic Problem

Since this is my very first logic problem, I’ll teach you how to set one up. First step, load up Microsoft Excel or Numbers (by Apple). If you want to use less electricity, get some graph paper instead. If you are using a spreadsheet document, resize all spaces to perfect squares. Then you will draw your logic problem grid.

Square size:

Before I go over number of squares, I should talk about square size. All categories should have the same number of items for every intersection to be a perfect square. If there are three items per category, there should be 3×3 spaces per square. If there are four items per category, there should be 4×4 spaces per square. If there are five items per category, there should be 5×5 spaces per square. If there are six items per category, there should be 6×6 spaces per square. And so on.

Since all of my logic problems have four items per category, there should be four rows and four columns per square. I like making problems with five or six squares more, but we’ll stick with four.

Number of squares:

The number of categories determines the number of squares. For every category you have, the difference in number of squares goes up by one. You need at least two categories. If there are two categories (which is never seen in a logic problem), there should be one square. If there three categories, there should be three squares. If there are four categories, then there should be six squares. If there are five categories, there should be ten squares. And so on.

My logic problems tend of have four categories, so there should be six squares. In addition, all squares should align to the left. The top row should always have one less square than the number of categories. Each row you go down, there should be one less square than the previous one, until you get to the bottom row, which has one square. At this point, you should have a an upside down staircase.

Setting up:

Once you drawn your grid, make sure the borders of each cell are thinner on the grid, but thicker in the full squares like I was talking about. Then you should add the labels on the outside. On the left, the labels should be horizontally aligned to match the rows horizontally. On the top, the labels should be vertically aligned to match the columns vertically.

When categorizing, make sure the items from the same category are always in the same order (top to bottom, left to right). One category cannot intersect with the same category. For a helpful hint, the squares from top to bottom are, category A, category D, and category C. The ones from left to right are category B, category C, and category D. By then, you should have set up your logic problems.

Now that’s the basics, it’s time for the puzzle.

Toys of the Sea

Tony the toymaker has always been making toys for kids’ meals in fast food chains, usually to promote the series they’re based after. For the September 2015 promotion at the fast food chain, Tony was making toys for the show Playtime in the Sea. It features four sea friends (Finley, Crunch, Shelly, and Leo) who like to play together as they fight Rex the evil orca from ending playtime from all over the sea. Tony has made four toys to be part of the entire collection. Each one of them has their own action as their special feature. The action can be triggered by the button on the stand each character stands on. The top face of the stand, the bottom face, the button, and the label with the character’s name all have the same colors. Can you find out which character is what type of animal, what color scheme does each have, and what unique action they have?



  • Finley
  • Crunch
  • Shelly
  • Leo


  • Sea Turtle
  • Shark
  • Sea Lion
  • Dolphin

Color Scheme:

  • Red
  • Green
  • Yellow
  • Blue


  • Light
  • Sound
  • Motion
  • Water Shooter


  1. Finley is either a dolphin (which doesn’t make motion) or a shark (whose color scheme is red).
  2. The sea lion holds a beach ball that lights up when the button is triggered.
  3. Crunch (who isn’t a dolphin) either has a blue color scheme or the action of sound.
  4. Leo’s color scheme is yellow, but isn’t a sea turtle.
  5. Either Shelly or the animal with the light feature has a green color scheme.
  6. The shark doesn’t have a water shooter feature (which isn’t triggered by the green button.
  7. The red button doesn’t trigger motion.
