London, UK – November 17, 2025 – Build the marble run of your dreams and let the good times roll in Cozy Marbles, a marble run and racing simulation game rolling onto Steam in 2026. Download the Steam Playtest today to jump into the nostalgia and get an early look at this warm and cozy marble simulator.
Developed by Pixel Pea Games and published by Mythwright, Cozy Marbles is a comfy game about building marble runs on a sunny afternoon. Using a huge range of bits and pieces, jump into a massive toybox and build the marble course you’ve always wanted.
Design awesome loops, twists and drops while tinkering with freeform construction tools and a rich library of parts. Engineer your run before rolling your marbles off on their own adventure, guiding them across complex courses, bouncing them over obstacles with boosters and ramps, and shooting them from cannons in an epic race to the finish.
Customize your marbles with a huge range of colours, facial expressions, stylish hats and silly little arms, all while unwinding to a relaxing lo-fi soundtrack. Perfect your marble masterpieces and share them with the world, and import courses from other builders to discover an entire world of mesmerizing marble runs.
“Cozy Marbles is a little game for big imaginations,” said Stuart Morton, Publishing Director at Mythwright. “From creating viral marble runs to classic marble races, Cozy Marbles gives players the tools to build any course they can dream of in a wonderful world of marbles. We’re very much looking forward to players rolling into Cozy Marbles with today’s Playtest, and can’t wait to share more on this marbelous new game as we get closer to launch.”
Cozy Marbles launches on Steam in 2026 and is the latest title to join Mythwright’s growing lineup of exciting upcoming games, including Kaiju Cleanup, TerraTech Legion, Bladesong and more. For the latest information, follow Mythwright on TikTok, Instagram, Bluesky and X, and visit mythwright.com.
