Nubby's Number Factory lands on mobile with full Steam content, no ads

Nubby’s Number Factory has finally landed on phones, and it did not arrive as a watered-down curiosity. The mobile release keeps the sun-exploding stakes, the pegboard chaos, and the game’s off-kilter humor intact, while bringing the full Steam experience to iOS and Android with no ads and no microtransactions.

That matters because Nubby’s Number Factory built its following on a very specific kind of nonsense. Solo developer Ethan Anderson, who releases work under MogDogBlog Productions, built a plinko-style roguelike where players launch a spherical character named Nubby down a pegboard to generate bigger and bigger numbers. Miss the quota and the sun explodes, which remains one of the strangest and most effective fail states in recent indie memory. The game has drawn easy comparisons to Balatro, Peggle, and Ballionaire, but it has always had its own rhythm, one part slot machine, one part math toy, one part panic.

The mobile version goes a step beyond a simple port. The paid app costs $4.99 on the App Store and Google Play, while a free lite version is also available for players who want to sample the formula first. The developer has said the lite build is a visually revamped clone of the Steam demo, while the full app is as close to a 1:1 copy of the Steam release as possible. The App Store listing puts the app at 459.8 MB, lists iPhone and iPad support, includes Game Center, and says the developer does not collect data.

Just as important, the launch keeps the mobile version clean. Anderson said there are no third-party ads or microtransactions in either build, and support was planned for both phones and tablets on iOS and Android. Controller support was not available at launch, with the developer saying it would be added later. For now, the pitch is straightforward: a premium roguelike with the same weird identity, just shrunk into a touch-friendly package.

The release also arrived after a longer wait than initially expected. Anderson had previously aimed for a December 2025 mobile launch, but held it back until version 1.4 content was ready rather than ship an incomplete port. By February, the game was waiting on store approval, and the launch eventually went live on both stores on April 17, 2026.

That extra time shows in the package. The mobile build includes version 1.4 content, including a perk system, special rounds, and Nubby Trials. It also lands with real momentum behind it: the Steam version, released on March 7, 2025, has reached an all-time peak of 4,839 concurrent players and roughly 18,000 reviews, with an Overwhelmingly Positive rating. Anderson has also used community updates to highlight localization work, including Brazilian Portuguese in version 1.4.3 and later French and Polish in version 1.4.6, which gives the mobile debut the feel of a small indie oddity graduating into a properly finished release.
