Can't Unsee — the UX game for UI design judgment
Tool powered by Can't Unsee on Amanda Hum and Alex Kotliarskyi.
Play the can't unsee game on cantunsee.space: pick the most correct UI between two designs—a UX game for hierarchy, typography, and visual detail.
What is the Can't Unsee game?
Can't Unsee at cantunsee.space is a free UX game by Amanda Hum and Alex Kotliarskyi. Each round shows two nearly identical interfaces; you pick the design that is most correct. Rounds test hierarchy, typography, color, alignment, and spacing—the small errors that slip into real products. A tutorial on cantunsee.space explains the format before scored rounds.
Tips for the Can't Unsee UX game
Use these habits to score higher and carry the same eye for detail into design reviews.
- Scan hierarchy before pixels: Ask which version has clearer heading levels, button emphasis, and content grouping. Most cant unsee rounds punish weak hierarchy before exotic color mistakes.
- Check alignment grids first: Misaligned icons, labels, and card edges are frequent traps. Trace vertical and horizontal lines across both options before you commit.
- Compare typography, not just fonts: Weight, size, line height, and letter spacing differ subtly. The correct UI usually has consistent type rhythm even when typefaces match.
- Use Compare after each pick: The publisher Compare view highlights what you missed. Treat wrong answers as calibration, not failure—especially early in a session.
- Watch color contrast pairs: Text on tinted backgrounds and ghost buttons are common. If two options look equal, suspect contrast or state styling (hover, disabled, focus).
- Finish the tutorial on cantunsee.space: Tutorial rounds explain scoring quirks before ranked play. Open cantunsee.space in a full tab once to learn the rules.

After playing this UX game
Pair interface judgment with targeted drills and production checks .
- Validate contrast on real pairs: When a round hinges on readable text, follow up at /color-contrast with the foreground and background you would ship.
- Train color recognition: Use /color-memory-game or /color-game when mistakes involve hue, saturation, or harmony rather than layout.
- Practice spacing and type: Try /kern-type for letter spacing and /pixactly for pixel-level dimension judgment between UX game sessions.
- Browse design games: See /tools/games for Method of Action vector games, CSS puzzles, and more UX-adjacent trainers.
