You're staring at a screen. One pixel is off. Just one. Most people wouldn't notice, but it's screaming at you like a siren in a library. That’s the "curse" of the designer, and honestly, it’s exactly what user interface design games are trying to beat into your brain.
Design isn't just about making things look "clean" or "modern." Those are buzzwords that don't mean much when a user can't find the checkout button. Real UI work is about spatial discipline. It's about understanding that a 2-pixel margin difference can make a layout feel claustrophobic or airy. If you’ve ever spent twenty minutes arguing about border-radius, you know the struggle.
The interesting thing is how we learn this stuff now. We used to just sit in Photoshop or Figma and move boxes until we got tired. Now, we play games. But these aren't games in the "Level Up Your Paladin" sense. They are focused, sometimes frustrating, high-speed tests of your ocular precision.
The Brutal Simplicity of Kern Type
Let's talk about Kerning. It’s the spacing between individual letters. Bad kerning is why some signs look like they’re shouting two different words. Mark MacKay created a tool called Kern Type that basically gamifies this nightmare.
You get a word. The first and last letters are locked. You have to move the middle letters to create a visually balanced flow. It sounds easy. It’s not. You’ll find yourself squinting at the screen, tilting your head, and trying to figure out if the "o" is leaning too hard on the "v."
The game gives you a score out of 100 based on how close you got to a professional typographer's solution. Getting a 100 feels like winning the lottery. Getting a 60 feels like you should probably sell your computer and go live in the woods. It teaches you that "mathematically centered" and "visually centered" are two completely different universes.

Can You Actually Spot the Fake?
Then there’s It’s Centered That, which is basically a psychological experiment disguised as a quiz. It presents you with a shape and a dot. Is the dot in the middle?
Sounds dumb, right?
But as the shapes get more complex—think polygons or weirdly weighted icons—your brain starts to play tricks on you. This is the core of user interface design games. They force you to acknowledge that your eyes lie to you. Icons in a circular button often need to be "optically adjusted." If you put a play triangle exactly in the center of a circle, it looks like it's falling off the left side because of the weight of the flat edge.
Designers have to learn to "cheat" the math to satisfy the eye. These games are the treadmill for that specific muscle.
Why Figma Is Not a Playground
Figma is a powerhouse. We love Figma. But Figma is for building, not for training your instincts. When you're in a project, you're thinking about stakeholders, color palettes, and whether the client will hate the font. You aren't focusing on the raw mechanics of sight.
That’s where things like The Bézier Game come in. If you've ever struggled with the Pen Tool in Illustrator or Figma, this is your trial by fire. It forces you to recreate shapes using the fewest points possible.
It’s agonizing.
You’ll click. You’ll drag. You’ll miss the curve by a hair. But after an hour, you realize you aren't fighting the tool anymore. You're thinking in vectors. This is the difference between a junior designer who makes messy, point-heavy paths and a senior who creates a perfect curve with two anchors.
The Hidden Psychology of "Can't Unsee"
Once you play these games, the world breaks. You start noticing that the "G" in the Google logo isn't a perfect circle. You see the uneven padding on the elevator buttons in your building. It’s a bit of a burden, honestly.
But for a professional, this "pixel-perfect" obsession is what separates a $50 logo from a $50,000 brand identity. It’s about intentionality. Nothing is an accident.
Color Perception is a Genetic Lottery
We don't talk enough about how everyone sees color differently. Some people are literally built to see more nuances in the spectrum. The Method of Action Color Game is a deep dive into this. It asks you to match hues, saturation, and complementary colors against a ticking clock.
It starts with easy stuff—match the bright red. Then it moves into tertiary colors and analogous schemes where the differences are microscopic.
I’ve seen veteran designers fail this. It’s a humbling reminder that our hardware (our eyes) has limitations. If you’re designing for accessibility, which you should be, these games show you why high contrast isn't just a "nice to have"—it’s a necessity for people whose color vision isn't tuned like a high-end monitor.
The Pixactly Phenomenon
How big is 40 pixels? Most people have no clue.

Pixactly asks you to draw a box of a specific dimension from scratch. "Draw a 120x80 rectangle." You drag your mouse and hope for the best.
It sounds like a party trick, but it develops a sense of scale. When you can look at a screen and know instinctively that a button is too small for a thumb-tap (usually under 44px), you’re designing faster. You stop guessing. You start knowing.
Real-World Stakes of Bad UI
We play these games because the stakes in the real world are actually pretty high. Look at the Citigroup disaster in 2020. A user interface that was so confusing it led to a $500 million mistake. They had a "manual" process involving checking specific boxes to prevent a full principal payment, and because the UI was a mess, they sent out half a billion dollars they didn't mean to.
A little more time playing user interface design games might not have saved them, but a better understanding of visual hierarchy and "confirmation" patterns certainly would have helped.
Design isn't just "pretty." It's functional safety.
Actionable Steps to Sharpen Your Eye
If you want to actually get better at this without going back to school, here is how you use these tools effectively. Don't just play them once and walk away.

- The 10-Minute Warmup: Before you open your design software for the day, spend ten minutes on Kern Type or the Bézier Game. It’s like a musician practicing scales. It gets your brain into "precision mode."
- Audit Your Own Work: Take a screenshot of a UI you built a month ago. Open it in Figma and draw red lines over everything that isn't perfectly aligned or balanced. You will be horrified at what you missed.
- Reverse Engineer Icons: Take a complex icon (like the Apple "Command" symbol) and try to recreate it using only basic geometric shapes—circles and squares. This teaches you the underlying structure of good UI.
- Test for Accessibility First: Use tools like the Adobe Color Wheel to check your palettes for color blindness. If your design fails the "black and white" test (meaning it doesn't work in grayscale), your UI is weak.
The reality is that user interface design games are just a gateway. They build the fundamental muscle memory so that when you're actually designing a complex dashboard or a mobile app, you aren't wasting mental energy on "does this look centered?" You already know it is. You can spend that energy on the bigger problems, like user flow and information architecture.
Stop guessing where the pixels go. Start training your eyes to see the grid that exists in the empty space between elements. It’s frustrating at first, but once you see it, you can’t unsee it. And that’s exactly the point.
