What is Nubby's Number Factory?

A single-player, 2D roguelike played on a pegboard. During each run, you launch the ball-shaped Nubby, combine more than 50 items to increase your score, and meet rising production quotas as a low-ranking factory worker responsible for keeping space and time intact.

What players say

97% of 19,582 reviews are positive · 93% of 259 in the last 30 days

Players praise the simple core loop, item synergies, and depth found by experimenting without guides. The most common complaint is that unpredictable ball physics and shop randomness make losses feel outside the player's control; some players say later physics updates made this worse.
