Cozy Marbles Rolls Out Jelle's Marble Runs Supporter's Pack on Steam

Cozy Marbles has expanded its build-and-race sandbox with a collaboration centered on Jelle's Marble Runs. The new Jelle's Marble Runs Supporter's Pack is available now for the Steam version of the game, bringing a selection of themed marbles and construction decorations intended for players who want to make courses with a Marbula One flavor.

The collaboration is not limited to paid content. A free update for the base game also introduces nine new courses inspired by Marbula One tracks, giving all Cozy Marbles players a set of ready-made circuits to explore, race on, modify, or use as inspiration for their own creations. Together, the DLC and free update put a major focus on the creative side of marble racing: building a venue, setting a visual identity, and then watching the small competitors navigate every twist, drop, booster, and unexpected launch.

What is in the Jelle's Marble Runs Supporter's Pack?

The Supporter's Pack is priced at £3.49 GBP, EUR3.99 EUR, or $3.99 USD on Steam. Its centerpiece is Jelle's recognizable flame marble, joined by 32 Marbula One team marbles. Those additions give players a broader themed roster for races and allow them to bring team-based visual flair to their tracks.

There are also two track-building items in the pack: a Marbula One billboard and a customizable Marbula One spectator stand. The latter is particularly suited to creators making full race-event environments rather than standalone mechanical layouts. A spectator area can help a track feel like a venue with a crowd-facing presentation, while the billboard offers another way to reinforce the identity of a circuit.

That distinction matters in a game built around open-ended construction. A marble run can be a simple test of gravity and momentum, but it can also become a deliberately staged competition. Decorative pieces help bridge the gap between those approaches, allowing players to create circuits that look prepared for an event as well as ones that function as a chain of physics-based obstacles.

"As a huge fan of Jelle, partnering with Jelle's Marble Runs to bring a slice of his magic to the world of Cozy Marbles has been a dream come true," said Cozy Marbles creator Tim Reiter. "It's so exciting to give players the opportunity to race iconic Marbula One teams across tracks inspired by Jelle's courses (or even build their own!), and I can't wait to see what our amazing community creates."

Nine Marbula One-inspired tracks are free

Players do not need the Supporter's Pack to access the update's new courses. The base-game addition includes nine tracks inspired by Marbula One circuits:

• Hivedrive
• Midnight Bay
• Minty Mania
• Momotorway
• Savage Speedway
• Shortcircuit
• Sleet Street
• Stardust Accelerator

For newcomers, these courses provide immediate examples of what a more structured marble-racing layout can look like. For experienced builders, they can serve as a starting point for experimentation. A player might study how a route handles speed, spacing, turns, vertical movement, and hazards before changing its components or building something entirely new around a similar idea.

The names also help communicate the update's aim. These are presented as courses inspired by Marbula One rather than merely a collection of generic new parts. The free content brings recognizable racing-circuit character into Cozy Marbles, while the paid pack supplies themed marbles and venue items for those who wish to take the presentation further.

A sandbox made for watching physics play out

Cozy Marbles is a laidback marble run simulation focused on construction and observation. Players build routes using a library of parts and freeform tools, then set marbles loose to see how their design performs. Its part selection includes spirals, twists, boosters, and drops, all of which can affect pace and route behavior in different ways.

The game also includes cannons that launch marbles and xylophone blocks that can be used to make music. Those features point to the broad range of possible creations. One course might emphasize a clean competitive run with a clear finish, another could focus on elaborate trick-shot launches, and another can function more like a musical machine. The basic premise is the same in each case: the player creates a system, then gets to see how the marbles travel through it.

Marble-run games are naturally suited to iteration because even a small adjustment can alter the final outcome. A booster placed too early may create a chaotic jump. A tight turn can slow down one route while another marble gets ahead. A drop can become a dramatic moment in a race or simply a satisfying piece of visual engineering. The ability to work in a freeform construction space makes that process central to Cozy Marbles rather than a side activity.

That creative loop is where the Jelle's Marble Runs partnership fits especially well. The included team marbles and themed venue pieces are not only collectibles; they are tools for staging a particular sort of race. Players can set up circuits with a more competition-like identity, populate them with the newly added marble designs, and create layouts that resemble a designed event rather than an isolated demonstration of parts.

Steam Workshop support extends the community side

Cozy Marbles includes Steam Workshop integration, allowing players to share their courses and import creations from others. In a building game, that kind of feature can greatly extend the practical value of an update. A new set of themed marbles, decorations, and course inspiration does not remain limited to one player's local experiments; it can contribute to a wider pool of shared layouts.

Workshop support also creates room for different kinds of creators. Some people may be interested primarily in carefully balanced races, where the question is whether every marble has a fair path to the finish. Others may pursue spectacle, producing large stadium-like builds filled with visual details. Musical constructions, unusual cannon sequences, and obstacle-focused courses all fit the game's toolset as well.

The Marbula One-inspired material could therefore lead to community creations ranging from close recreations of a race-day atmosphere to wholly original tracks that simply use the new marbles as a visual theme. Reiter's comments specifically point to the prospect of players building their own courses, placing the emphasis on what the community makes with the update rather than on a fixed campaign or prescribed set of events.

A collaboration that serves both new and existing players

The release is structured in a way that gives existing Cozy Marbles owners fresh material regardless of whether they purchase the DLC. The nine courses are part of the free update, so players can immediately try new layouts inspired by the collaboration. The Supporter's Pack is an optional purchase for those who want the flame marble, the 32 team marbles, and the two Marbula One-themed construction items.

For prospective players, the update also offers a clear snapshot of Cozy Marbles' appeal. It is a game about designing, testing, watching, and refining marble runs. The collaboration adds a recognizable competitive-racing angle to that premise, but the wider experience remains rooted in flexible building tools and a collection of mechanical pieces that can be arranged in countless ways.

With the Supporter's Pack now on Steam and its accompanying free update available to the base game, Cozy Marbles players have more ways to turn a quiet construction project into a miniature marble-racing event. Whether the goal is a carefully planned circuit, a music-making contraption, or a chaotic course full of launches and drops, the new material provides both themed decoration and additional inspiration for the next run.
