Onceblock
Independent game studio

Games that start in a tab.

We build small puzzle games that open in a browser and are playable in seconds — no store, no install, no account. The first one is a parking lot you have to untangle.

Playable demo Parko

A parking lot, jammed solid. Drag each car out in the right order before you run out of moves. One rule you understand in a second, and 151 levels that keep bending it.

One rule, deep room

We like puzzles you understand before anyone explains them, with enough underneath to keep you there. If a game needs a tutorial screen to make sense, we go back and simplify it.

02

Browser first

Everything we make runs instantly in a tab, then gets packaged for phones. No download screen between someone hearing about a game and playing it.

03

Built in the open

Unity, WebGL, and a build small enough to load on a phone connection. We ship the same thing we test, and we test it on the network you actually have.

Publishing, partnerships, or just curious what we’re building next.
