Hue9 started as:
“What if Sudoku worked with colors instead of numbers?”
Now the app is suddenly going crazy.
The last 28 days have been the biggest growth spike since launch 🚀
Indie reminder:
boring markets are often hiding massive opportunities.
My brain won’t stop lately.
Hue9’s next big update will bring color-blind mode, offline pause, Theme Lab, custom palettes, alternate icons, and cleaner settings.
And I’m already thinking about what’s next:
VS Mode via Game Center.
Same board. Challenge a friend. Watch their progress. Fastest color-sudoku solver wins.
Would you play it?
I’ve spent the last 4 days adapting Hue9, a color-based Sudoku, to be genuinely playable for colorblind users.
The easy fix would have been “add a colorblind palette”. But that still relies on color as the main API.
So I reworked the system around non-color cues: each value can be represented by a distinct symbol, pencil marks scale responsively, selected cells / related cells / hints have their own visual states, and the board keeps a clear hierarchy without depending on hue.
It was not a small UI tweak. It was a full pass on how the game communicates information.
Hard work, but absolutely worth it.
@seraleev Massive milestone, Viktor! Congrats!
Your journey is such an inspiration. I’m sitting around $2K after 3 months with one app, and seeing this makes me want to push even harder. Hopefully I'll hit those kinds of numbers one day!
@seanallen_dev@BitrigApp Congrats on the new role! Our loss is Bitrig’s gain.
The community will definitely miss your courses, but I know you’re going to do amazing things over there. Crush it!

If you told me a year ago that making a Sudoku game based on colors would be funding my tech cravings, I would’ve laughed.
Month 1 of Hue9: Paid for my Apple Dev Program renewal.
Month 3: Just paid for the upcoming iPhone 18 Pro Max.
Next goal: Studio Display.
Never underestimate a simple idea executed with passion. Thank you all!
