The Game

Nubby’s Number Factory is a plinko-style roguelike developed and published by MogDogBlog Productions and released on Steam on 7 March 2025. You are a low-ranking employee at a number factory, and your job is to launch a small spherical friend called Nubby down a pegboard to make bigger and bigger numbers. Miss your quota and, according to the Steam page, the sun explodes – the story is a daft excuse for the loop, and it is all the better for it.

Each round you aim Nubby at a board of numbered pegs. Every peg you hit scores its value and shrinks (or pops), and you need to reach the round’s target score before Nubby falls out of the bottom. The target is worked out from the total value of every peg on the board and then multiplied by a number that grows as you visit more shops, so you cannot just coast. Every few rounds you visit the Nubby-Mart to spend coins on items that fill up to seven slots, and these are what the game is really about: items that double pegs, pop pegs, add flat points or trigger each other in chains, plus perks and a second shop called Cafe Nubby that you unlock by buying all the extra slots.

A run lasts 80 rounds, with a boss every 20 rounds and the scenery changing zone as you go, and after that Endless mode starts. The Steam page promises over 50 unique items and the build variety is the main draw – the screenshots below go from a simple round 2 board to the glorious chaos of round 97.

Worth it?

Nubby’s Number Factory costs £4.29 on Steam in the UK (price checked on 25 October 2026). The lowest UK price SteamDB has recorded is £2.14 (50% off), so a sale makes it a no-brainer. It is available on PC (Windows only) and is rated Playable on Steam Deck.

It is a very easy recommendation on price alone. Steam reviews are Overwhelmingly Positive, at about 97% positive. The standout feature is the way builds snowball: finding an item combination that sends the numbers into the millions, billions and beyond is hugely satisfying. The main criticism is randomness – the bounces and shop offers can sink a run that looks like it is going well, and a single bad drop can undo a build, there are times when the game feels quite punishing and has definitely resulted in some rage quits.

Overall, it is a cheap, addictive game that is perfect for short sessions, and well worth the price.

Tips

  • Early on, buy items that give flat points, such as Cheese House, Poop Butt, Finger Puppet, Squirmy or Sea Cucumber – they earn you restocks and coins quickly, which lets you afford better items
  • Sell those flat-point items once they stop contributing – by the mid and late game the target is far bigger than they can handle
  • The target score is based on the total value of all the pegs on the board, so look for items that add value to pegs rather than just popping them
  • In the late game the target outgrows the total value of the board, so clearing every peg is not enough – you need doublers and items that raise peg values, such as Kazoo, which doubles a random peg every 1.5 seconds
  • Buy the extra item slots (5 coins each, up to a maximum of 7) – once you have bought them all you unlock Cafe Nubby, which sells single-use food items
  • Freeze an item in the Nubby-Mart by dragging it onto the ice (snowflake) icon so it stays in its slot when you reroll or come back later, and click it to unfreeze
  • Right-click an item in your inventory to sell it
  • Perks and items that force-trigger your item slots work well with doublers like Kazoo
  • Expect a boss every 20 rounds, with the main run finishing at round 80 before Endless mode begins
  • Mods: there is no Steam Workshop support. Unofficial modding is done with the Undertale Mod Tool on the game’s data.win file, and the Nubby’s Forgery modloader on GitHub was built for version 1.3.1.5, so it may not work with the current version. Always back up your data.win and your save first
