Select.Supply has always been about discovering well-crafted products. I spend a lot of time curating tech, tools, books, and other items that are worth your attention. But I recently asked myself a simple question: what if I could also help people have fun while learning something new?
That question led us to build two browser-based games, now live on the site under a new “Fun” section in the navbar. No downloads, no signups, just click and play.
Here’s what I made and why.
MindMaze: A Trivia Game Set in a Cursed Castle
MindMaze is a game where you explore a castle made up of rooms connected by doors. To move from one room to the next, you have to answer a trivia question or complete a memory challenge. The goal is to find the stairs on each floor, climb five floors, and collect 20,000 points to lift the castle’s curse.
Before you start, you pick your difficulty level and choose from nine trivia categories, including geography, history, life science, physical science, art and literature, and more. The harder the difficulty, the more points each correct answer is worth, but the questions get tougher too.
Along the way, you meet characters like a wizard, a jester, a knight, and even a cat. They offer hints and bits of story. You also get a limited number of torches that reveal the shortest path to the stairs on your current floor.
What makes MindMaze interesting is how it mixes knowledge testing with exploration. You are not just answering questions in a list. You are navigating a maze, making choices about which door to try, and managing your resources. It feels more like an adventure than a quiz.
ChipBuilder: Build a Computer From Scratch
ChipBuilder takes a completely different approach. It is an educational game where you literally build a computer, starting from the most basic building blocks.
You begin with simple logic gates like AND, OR, and NOT. Then you combine them into more complex circuits like adders and multiplexers. Eventually you design memory units, build an ALU (arithmetic logic unit), and put together a working CPU. In the final chapters, you write assembly programs that actually run on the CPU you built.
The game is organized into eight chapters with 32 levels total. Each level has a briefing that explains the concept you are about to learn, an objective to complete, and test cases that verify your circuit works correctly. There is also an XP system and engineer ranks that track your progress.
ChipBuilder was inspired by courses like Nand2Tetris. I wanted to make that kind of learning accessible in a browser, with a visual circuit editor and immediate feedback. You drag components onto a canvas, wire them together, and run simulations to see signals flow through your design.
Why Games on a Product Curation Site?
It might seem like an odd fit. A site that recommends products now has games? But the way I see it, Select.Supply is really about finding things that are worth your time. That includes physical products, but it can also include experiences.
Both of these games teach you something. MindMaze tests and expands your general knowledge across many subjects. ChipBuilder gives you a hands-on understanding of how computers actually work at the hardware level. These are not throwaway time-wasters. They are the kind of things you finish and feel like you got something out of.
I also just think the web should have more fun, free things on it. No ads, no paywalls, no data collection. Just well-made interactive experiences.
You can find both games by clicking “Fun” in the navbar at [select.supply](https://select.supply), or go directly to:
- MindMaze: https://select.supply/game/mindmaze
- ChipBuilder: https://select.supply/game/chipbuilder
They work on desktop browsers and are completely free. I would love to hear what you think. If you have feedback or ideas for new games, reach out through the contact page on the site.
I am just getting started with this. There is a lot more we want to explore, and if people enjoy these, I will keep building.
