Welcome to Knossos Games!

I'm Tim Boester, an educational psychologist and author of the puzzle column in Imagine magazine for over twenty years. Here you'll find the mazes, hybrids, and puzzles from the magazine, plus additional resources like my puzzle-writing blog and isometric graph paper.

Cell Wall Transport System: These puzzles are based on the three types of proteins used to transport substances into and out of cells (uniport, antiport, and symport). Instead of a traditional finish line, use objects to move through the protein-based passageways in the puzzle. The puzzle is solved once all of the objects have been moved to receptors scattered throughout the puzzle.

Gerrymandering: A set of precincts needs to be grouped into districts. Your nefarious task is to gerrymander the districts so that the desired election result is achieved, regardless of which side (yes or no votes) has the majority of votes or precincts. These puzzles will hopefully enlighten solvers on how incredibly influential district arrangement can be on election results.

Neuron Activation Level: When a neuron receives a signal from enough surrounding neurons, the neuron then passes along the message. This is known as the neuron’s activation threshold. In these puzzles, given the set of neurons and their activation states, can you determine how to assign the available neuron activation thresholds?

The content of Knossos Games is organized into broad categories: mazes, hybrids, puzzles, and logic problems. I've also kept the old pages of puzzles grouped by category or in order of their publication as I continue to update the site.

Check out my blog about puzzle-making, the web site, and other math-related topics. The most recent posts highlight the article on logic I recently wrote for Imagine magazine, including the sidebar on logic and puzzle books I have and referenced for the article. There are also origin stories for the holiday puzzles: both the reindeer games problem and the Christmas trees problem.

I use isometric (triangular) grids in many of my puzzles. Unfortunately, isometric graph paper can be hard to find, and Adobe Illustrator still doesn't have a built-in isometric grid available. I spent a lot of time perfecting isometric grids for my own use, and eventually realized that other people might find it useful as well.

Stay tuned for more blog posts and content updates. Thanks for visiting!
