12 Number Go Up Games for When You Just Want the Number to Get Bigger

Number go up games, explained and picked: what the phrase means, why 1.79e308 matters, and 12 games where watching numbers grow is the whole point.

Source-checked guideMaintained by Maxwell PrehodaHow we choose

"Number go up" is shorthand, half joke and half sincere, for the pleasure at the centre of incremental games: you press a button, a number grows, you spend it to make the number grow faster, and soon it is too big to read without scientific notation. A number go up game is one that strips away almost everything else. No story to follow, no characters to care about, just growth, and better ways to grow.

The genre's touchstone is Antimatter Dimensions, which has its own entries in our other guides. This list is the rest of the family: free browser games built around maths, a couple of polished Steam games, and one that runs the joke backwards. Ratings come from galaxy.click and Steam as of November 2026, and Steam prices are US prices that can change.

01

NGU Idle: best for a game literally named after the phrase

Platform: Steam, Browser · free-to-play

NGU stands for Numbers Go Up, and 4G's Steam page opens with "Everyone likes numbers that go up." Under the joke is a deep RPG idler: you split energy and magic across dozens of systems, fight over 300 hand-drawn bosses, and loot more than 350 items. Even your upgrades have upgrades, as the store page puts it.

It is free to play on Windows, and 96% of 12,996 Steam reviews are positive. The humour is relentless and silly, which keeps the long grind light.

Pick it if you want hundreds of hours of number growth with jokes on every screen.

Watch out for: Steam lists in-app purchases. The game has a lot of systems and a fairly cluttered interface, so the first hour is mostly working out what each bar does.

02

(the) Gnorp Apologue: best for number growth you can watch happen

Platform: Steam · paid

Myco's (the) Gnorp Apologue is about small beings called gnorps who want delightfully excessive wealth. You hit a rock, it outputs shards, and gnorps carry the shards back so you can buy more gnorps and structures. The store page promises visuals to match the numbers, and it delivers: the screen fills with tiny workers, machines and chaos.

It costs $6.99 on Windows, and 96% of 8,143 Steam reviews are positive.

Pick it if pure abstract numbers bore you but you still want that exponential feeling.

Watch out for: It is far more active and visual than the browser games here. Late game the screen can get busy enough to tax a weak laptop.

03

Revolution Idle: best for reaching Infinity at 1.79e308

Platform: Steam, Mobile · free-to-play

Revolution Idle fills coloured circles to grow a number, prestiges to raise your multiplier and exponent, and sends you toward ~1.79e308, where Infinity triggers and a new layer opens. That number is not arbitrary: it is the largest value a standard double-precision number can hold, which is why so many incremental games treat it as a wall to break.

It is free to play on Windows (and mobile), with offline progress, and 87% of 12,508 Steam reviews are positive. The store page claims more than 2 million players.

Pick it if you want a clean, abstract game where every reset visibly makes the next run faster.

Watch out for: Steam lists in-app purchases. It is deliberately minimal, so if you need a theme or a reason, this has neither.

04

Swarm Simulator: best for units that make units that make units

Platform: Browser, Mobile · free

Swarm Simulator grows an alien hive. Larvae become drones, drones are produced by queens, queens by nests, and each tier produces the tier below it. That stacked production is the purest form of number go up: the growth is not just fast, it accelerates.

It is free in the browser, our catalog rates it about 80% idle, and the site shows what you earned while away when you come back.

Pick it if you want to understand why these games feel the way they do. One evening with it explains exponential growth better than a textbook.

Watch out for: The site says it does not support Safari; use Chrome or Firefox. Our catalog marks it as no longer updated, and saves live in browser storage, so copy your save text now and then.

05

Incremental Mass Rewritten: best for absurd scale, from a weight lift to the multiverse

Platform: Browser · free

MrRedShark77's Incremental Mass Rewritten starts with you lifting weights to gain mass. Then you become a black hole, then atomic generators, stars and stranger things, across eight prestige layers. It holds 4.5 stars from 618 ratings on galaxy.click, with over 310,000 hours played there.

The web version is free. A Steam version co-developed with Oni Gaming is listed for Q4 2026.

Pick it if you want the numbers to get comically large, and stay that way.

Watch out for: The web version's last update on galaxy.click is from July 2023, and our catalog marks it dormant. The upcoming Steam release lists in-app purchases.

06

Idle Spiral: best for maths you can see as a growing spiral

Platform: Steam, Mobile, Browser · free

Idle Spiral's goal is to make a spiral grow farther from the origin. Upgrades are mathematical equations, but the store page says you hardly need to understand the formulas to play, and that you come to understand the mechanics as you go. Several layered prestige resets keep pushing the spiral outward.

It is free on Steam for Windows and Mac, and on mobile and web. 79% of 1,905 Steam reviews are positive.

Pick it if you like the idea of maths as something visual rather than a spreadsheet.

Watch out for: It has 11 DLC items on Steam, the most of any free game here, so check what is sold before you invest.

07

Ordinal Pringles: best for numbers so big they need ordinals

Platform: Browser · free

Ordinal Pringles is a ground-up remake of Ordinal Markup, a game about climbing ordinal numbers, the notation mathematicians use for infinities beyond infinity. Its galaxy.click page tags it googology, the study of very large numbers, and says it adds a new prestige layer and less waiting than the original.

It holds 4.5 stars from 208 ratings and is free in the browser.

Pick it if regular big numbers no longer impress you.

Watch out for: The page says it is in heavy development, and its last listed update was in February 2025. It is also tagged active, so it wants attention.

08

Algebraic Progression: best for players who remember high school algebra fondly

Platform: Browser · free

Algebraic Progression by randomtuba builds its number growth out of algebra: variables, functions, square roots and the quadratic formula. Its galaxy.click page lists three prestige layers and two side prestiges.

It holds 4.4 stars from 325 ratings, with nearly 169,000 hours played. It is free in the browser.

Pick it if you want the number to go up because you wrote a better equation.

Watch out for: The page says it is primarily active rather than idle, so it is not one to leave alone for a day.

09

Distance Incremental: best for a few days of running toward infinity

Platform: Browser · free

Jacorb's Distance Incremental has a one-line pitch: run to the edge of infinity. You gain distance, reset for bigger multipliers, and automate the climb. Jacorb also made The Prestige Tree, and this one shares its taste for tidy layered resets.

It holds 4.5 stars from 231 ratings on galaxy.click and is tagged as taking a day to a week to beat. It is free in the browser and tagged text-based.

Pick it if you want a number go up game with a clear finish in sight.

Watch out for: It has not been updated on galaxy.click since May 2023, so treat it as finished as is.

10

Omega Layers: best for unlimited prestige layers on a Greek letter ladder

Platform: Browser · free

veprogames describes Omega Layers as basically Antimatter Dimensions with unlimited prestige layers. You buy generators, clear challenges and climb a ladder of Greek letters, each a new reset layer above the last.

It holds 4.2 stars from 159 ratings on galaxy.click and is tagged as taking a day to a week.

Pick it if the moment you love most in these games is unlocking the next layer.

Watch out for: Comments mention that some late-game progress is slow, and the page is tagged active.

11

Check Back Reclocked: best for slow, idle growth you check on through the day

Platform: Browser · free

Check Back Reclocked is a full remake of Check Back, rebuilt for better pacing and a quicker sense of numbers going up, in the developer's words. It uses a number library that supports values up to about 1e1.8e308, which is a number with roughly 1.8e308 digits.

It was posted in March 2026 and updated as recently as October 2026. It holds 4.2 stars from 192 ratings on galaxy.click, and is tagged idle with a length of days to weeks.

Pick it if you want a modern, actively developed number go up game for a background tab.

Watch out for: It is also tagged micro-management, meaning frequent check-ins pay off, and it is still in development, so systems are changing.

12

Click To Continue: best for the joke reversed: number go down

Platform: Steam · paid

Basolute's Click To Continue puts you in a white room with one button and calls itself a decremental game, because increasing numbers are overrated: here you watch numbers go down. Each panel opens after enough clicks, revealing upgrades, surprises or nonsense, and there is a hidden truth to uncover.

It costs $4.99 on Windows, and 92% of 451 Steam reviews are positive. It is short and funny, and it lands best after you have played a few of the games above.

Pick it as a palate cleanser that understands the genre well enough to mock it.

Watch out for: It is a short clicker, so you will be clicking a lot, and our catalog rates it about 25% idle.

How to choose a number go up game

They all make a number bigger. They differ in how they make it feel.

01

Choose how abstract you want it

Pure abstraction: Revolution Idle, Omega Layers, Ordinal Pringles. Some theme and visuals: (the) Gnorp Apologue, Idle Spiral, Incremental Mass Rewritten. Jokes everywhere: NGU Idle.

02

Choose how much maths you want to see

Algebraic Progression and Ordinal Pringles put the maths on screen and make it the game. Idle Spiral shows equations but does not require you to follow them. Swarm Simulator and Revolution Idle hide the maths behind simple rules. If you want more, our math incremental games list goes deeper.

03

Choose active or idle

Algebraic Progression, Ordinal Pringles and the Gnorp Apologue reward attention. Swarm Simulator, Revolution Idle and Check Back Reclocked are happier in a background tab. Our truly idle games list is the place to go if you never want to click at all.

Make a number bigger tonight

For the clearest dose of the feeling, open Swarm Simulator for half an hour and watch the tiers start producing each other. If that hooks you, Revolution Idle and NGU Idle will keep going for months.

If you are curious how games handle numbers past 1.79e308 at all, that is a story about libraries like break_infinity.js, and we cover it in a separate guide for developers.

Common questions

What does number go up mean?

It is slang for the simple pleasure of watching a number increase, and in games it describes incremental and idle games, where growing a number faster and faster is the main goal. The phrase is used both as a joke and as a sincere description of why these games are fun.

What is a number go up game?

An incremental game that keeps the focus on growth itself: you earn a resource, spend it to earn faster, and reset for multipliers. NGU Idle, Revolution Idle and Swarm Simulator are clear examples.

Why do so many incremental games stop at 1.79e308?

About 1.79e308 is the largest value a standard double-precision floating point number can store, which is how JavaScript and many engines hold numbers. Games either treat it as a wall called Infinity, as Antimatter Dimensions and Revolution Idle do, or use a big number library to go past it.

What does NGU stand for in NGU Idle?

Numbers Go Up. The Steam page invites you to experience the joy of Numbers Going Up.

Are number go up games free?

Most are. Every browser game on this list is free, and NGU Idle, Revolution Idle and Idle Spiral are free to play on Steam with optional purchases. (the) Gnorp Apologue and Click To Continue are paid.
