Tessellate

Split-screen co-op for the games you already own.

One PC, one screen, a controller each. Tessellate runs a copy of the game for every player and tiles them, so the whole couch plays together.

How it works

Three steps from the sofa

  1. 1

    Pick a game

    Tessellate finds the Steam games you already have and shows which ones play split-screen.

  2. 2

    Press Play

    It starts a copy for each player, gives each one its own profile and saves, and tiles the windows.

  3. 3

    Pads join

    Everyone presses a button on their controller and drops into their own corner of the screen.

Features

Everything a couch night needs

Profiles for everyone, controllers that stay with their player, per-player sound, and a launcher that tidies up after itself. Plus a few things just for fun: go on, poke them.

Game cards

Every game you play together earns a card, from Bronze to Holo. Tilt one and watch it shine.

Couch potatoes 100 hours together. Everyone's character earns the Couch crown.

Your 2026 together 142 hours over 38 game nights

Achievements and Wrapped

Badges for the nights you share, and a recap of your year together at the end of it.

Everyone's pad is awake.

Controllers that nap

A pad falls asleep mid-game? Press a button and it finds its player again. Nothing restarts.

FAQ

Questions, answered plainly

Which games work?
The Library's Add game shows what Tessellate knows how to split: games with a built-in pattern, games that already play together on one screen (native co-op), emulators, and patterns converted from the Nucleus hub. Anything else can still be added as an .exe; whether it splits well depends on the game.
What is a pattern?
Patterns (previously called handlers). A pattern is a small file that tells Tessellate how to start one game for several players: which exe, how many players, and how to keep their saves and settings apart. Some are built in, new ones come from the pattern feed, and Settings > Patterns & hub lists them all.
A controller fell asleep mid-game. What now?
Press a button on it. Tessellate remembers whose pad it is and hands it back to the same player when it wakes, without restarting anything.
