We make puzzles
that don't let go.
xo9 is an independent studio crafting tactile, minimal games for mobile. Our first title, Tricky Triangle, is coming to the App Store and Google Play.
One board. Fifteen pegs.
One that has to remain.
The classic peg jump,
rebuilt for your thumb.
A triangle of fifteen pegs. Leap one peg over another into an empty hole, and the peg you jumped is gone. Keep going until you can't — and try to leave just a single peg standing.
We believe the best games are the ones you can explain in a sentence — and lose an afternoon to.
xo9 is a small, independent studio. We build deliberate, beautifully restrained games for the few minutes you have between everything else — no noise, no dark patterns, no endless menus. Just a clean idea, polished until it feels obvious. Tricky Triangle is where we start.
Minimal by design
One idea, executed completely. If it doesn't earn its place, it's gone.
Made for the thumb
Built for mobile first — quick to open, easy to hold, hard to put down.
Crafted, not churned
We ship when it feels right, not when a calendar says so.
Say hello.
Press, partnerships, playtesting, or just to say you got it down to one — we read every message.
