NumWorlds is a cozy 3D number-chaining puzzle on Steam Early Access from Black Pug Studio in Galway. You chain adjacent digits on a board until their sum matches the target, then explore handcrafted Unreal Engine 5 biomes such as Atlantis and the Cretaceous, with Ireland on the community roadmap. There is no timer pressure in the core loop, and Infinite Mode adds optional Steam leaderboards for endless practice on PC.

Why is NumWorlds launching in Early Access?

Early Access lets players shape the Steam PC campaign with the studio. Community feedback guides new biomes, Infinite Mode polish, quality-of-life updates, and the Ireland Celtic world still ahead. Wishlisting is the cleanest way to follow honest roadmap notes without invented ship dates.

What is Infinite Mode?

Infinite Mode is an endless number-chaining challenge with Steam leaderboards. You keep the same calm chaining skill from the campaign, play at your own pace, push high scores, and compare runs with other Early Access players on PC when you want optional rivalry.

Which platforms is NumWorlds on?

The main NumWorlds experience is coming soon on Steam for PC (Windows). A mobile version is also available on the App Store and Google Play. For the Unreal Engine 5 campaign, Infinite Mode leaderboards, and Early Access roadmap, wishlist on Steam.

Is Ireland playable yet?

Ireland is on the Early Access roadmap as a Celtic cliffs and folklore biome from our Galway studio. Atlantis and Cretaceous are the worlds you can explore in the current campaign framing. Follow news and the Ireland world page for concept art and playable milestones.

NumWorlds is made by Black Pug Studio Ltd. in Galway, Ireland, built in Unreal Engine 5. The studio is shipping Steam Early Access with a community-shaped roadmap across handcrafted biomes and number-chaining modes.
