Singularity

What is Singularity?

Singularity is an incremental simulation from developer Ne0Jiku that takes an unusual subject: a star, followed from the stardust cloud it condenses out of all the way to the black hole it becomes. Ten elements drive production — Stardust, Plasma, Dark matter, Antimatter, Chronon and Strange matter among them — and each one shapes output in its own way rather than simply scaling a number upward.

That premise runs in three layers. The star itself climbs seven tiers: Nebula, Protostar, Star, Giant, Supernova, Neutron star and Black hole, each faster than the last and each unlocking new mechanics. Around it, Novas earn shards that light stars in constellations. Then, once the collapse happens, the black hole begins devouring galaxies and a larger one forms in its place.

It is an HTML5 build that runs in a browser with nothing to install, and it is playable straight away. It is free, published 26 October 2026, and offered in English and French. It is also explicitly unfinished: balancing is still moving and more content is planned beyond Act 2.

How to play

Every run starts with a build. One element goes at the core, others are fused around it, and each pairing resolves into one of 45 reactions. Reactions drive production, but they are never free: a configuration carries a stability cost, so the heaviest stack is not automatically the right one.

Production feeds Novas. Every Nova pays shards, and shards light stars in constellations — a lit star is a law, a rule that holds until the next singularity. Because laws die with the reset, part of each run is deciding which rules are worth carrying forward.

The Black hole tier is not the end. Collapsing the galaxy yields data, and data is spent on a research map shaped like the Milky Way. Each collapse grows the galaxy and automates part of the early game through autopilot, auto-relight and a comet catcher. Probes travel in real time, even while the game is closed, and return relics that can be equipped and combined into sets. Fourteen anomalies rewrite the rules of individual galaxies, and galactic challenges put a whole galaxy under pressure.

Controls

Singularity is a single-player browser game built on decisions rather than reflexes. The input that matters is choice: which element takes the core, which fusions surround it, whether the resulting stability cost is acceptable, and which constellation laws to light with Nova shards.

Play is built to survive interruption. The first hour of away time counts immediately, and everything after it fills a time reserve that can be spent at any chosen moment, so a session does not need to be continuous to be productive. Probes keep travelling in real time while the game is closed and deliver their relics on return.

Progress is stored on the device, and export and import move a save between devices. The whole structure — constellations, research map, relic sets — is built around one player's own progression, in English or French.

Tips for your first run

Early play is mostly about the shape of the build and the timing of the reset, and a handful of habits make the first hours smoother.

• Watch the stability cost before adding another fusion. One element sits at the core and the rest fuse around it, and each addition has a price attached.
• Trigger Novas often. Shards are the only route to constellation stars, and every law expires at the next singularity, so early lights have longer to pay off.
• Bank the time reserve instead of spending it on reflex. Away time beyond the first hour accumulates and can be released whenever it is most useful.
• Treat the nine challenges as controlled experiments. They twist the rules — one removes fusion entirely, one destabilises the core, one limits the run to three minutes — and each hands back a key law.
• Work through the catalog. Forty stellar types are there to discover, and forty feats provide permanent boosts that outlast any single run.

Content and replayability

The content stack is unusually deep for a browser incremental. Ten elements combine into 45 reactions, and those reactions sit beneath seven progression tiers, so the build space is wide before any meta layer is touched.

Beyond a single run there is a catalog of 40 stellar types, 40 feats that boost everything permanently, and nine rule-twisting challenges that pay out laws. Act 2 adds galaxy collapses, the Milky Way-shaped research map, and automation of earlier steps through autopilot, auto-relight and a comet catcher.

On top of that sit the variables: 14 anomalies that change the rules of a given galaxy, galactic challenges that put an entire galaxy under pressure, and probe-delivered relics that can be equipped and combined into sets. Because each collapse grows the galaxy, the numbers behind the automation keep climbing.

Presentation and performance

The design leans minimalist and relaxing, and the setting is space in the literal sense: a star, the constellations built from its Novas, and a research map shaped like the Milky Way. Four screenshots accompany the build, and the visual language implied by those tags is restrained rather than theatrical.

As an HTML5 build it opens in a browser tab without an install step. Saves stay on the device, with export and import for moving between them, and the interface is offered in English and French.

The project is in active development, so pacing and balance are still moving. A run finished this week may not behave the same way next week, which is worth knowing before committing to a long optimisation plan.

Who should play it

This is a game for players who like watching a system build itself. Idle and incremental veterans will recognise the rhythm: production, a reset that converts progress into rules, and automation that erodes the early grind with every collapse.

It also suits tinkerers. Ten elements, 45 reactions and a stability cost attached to every build reward the player who wants to test combinations and compare output rather than simply wait. Completionists have 40 stellar types and 40 feats to work through, plus nine challenges and 14 anomalies.

The caveat is development status. Balancing is still shifting and more content is planned after Act 2, so anyone who needs a settled economy should know that going in. Everyone else can try it in a browser at no cost.
