Computer Lunch's incremental game starts you clicking a single cell and ends somewhere past the technological singularity, covering roughly 4.5 billion years on the way. Three separate simulations run side by side: the Primary Simulation, the dinosaur-focused Mesozoic Valley, and the astronomy-focused Beyond, each with its own currency and its own reset. The Reality Reboot rework in November 2025 moved the first prestige far earlier, which means older walkthroughs get the pacing badly wrong.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Entropy generation
Entropy is the base currency of the Primary Simulation, earned by tapping anywhere on screen and then automated by generator nodes you buy on the evolution tree. Each generator raises passive output, so the opening hour is really a race to stop clicking.
Ideas and the tech tree
Ideas unlock once the tree reaches intelligence, and they buy the civilization side of the game: agriculture, industrialization, information technology and everything after. Entropy and Ideas run as two parallel economies that both feed your prestige payout.
Metabits prestige
Metabits are produced by your Entropy and Ideas output together, then spent in the Reality Engine on permanent multipliers. Since the Reality Reboot, the first prestige unlocks when you reach Ideas rather than at the Singularity, so your first reset arrives hours earlier than old guides claim.
Mesozoic Valley mutations
The dinosaur simulation runs its own currency and its own reset. Dropping an Asteroid wipes the dinosaur tree but keeps your traits and Mutagen, and Mutagen even survives a full Primary Simulation prestige. That makes it the safest long-term investment in the game.
Stardust in the Beyond
The astronomy simulation runs on Stardust, collected by tapping and generated by celestial bodies you have already unlocked. It opens with the Solar System and works outward, with Mars arriving as the fifth celestial body at Rank 1.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Entropy | The Primary Simulation's base currency, earned by tapping and then by generator nodes. | Buying life generators and unlocking new species |
| Ideas | Unlocked once the tree reaches intelligence, then spent across the civilization and technology upgrades. | The technology tree from agriculture through information technology |
| Metabits | The prestige currency, spent in the Reality Engine on permanent multipliers that carry through every reset. | Permanent multipliers that make each run faster than the last |
| Stardust | The Beyond's currency, collected by tapping and generated by celestial bodies you already own. | Buying planets, moons and stars out past the Solar System |
| Darwinium | The premium currency, available through purchases but also through achievements, daily rewards, Mesozoic Valley missions and Beyond missions. | Permanent upgrades rather than temporary time skips |
Entropy: The Primary Simulation's base currency, earned by tapping and then by generator nodes. Every upgrade on the life half of the tree is priced in Entropy, and the growth curve means a generator bought ten minutes sooner compounds for the rest of the run.
Ideas: Unlocked once the tree reaches intelligence, then spent across the civilization and technology upgrades. Ideas and Entropy production together decide how many Metabits a prestige will pay out.
Metabits: The prestige currency, spent in the Reality Engine on permanent multipliers that carry through every reset. Since the Reality Reboot the first prestige lands at Ideas rather than at the Singularity, so Metabit income starts far sooner than it once did.
Stardust: The Beyond's currency, collected by tapping and generated by celestial bodies you already own. It buys planets, moons and stars, starting inside the Solar System and pushing outward from there.
Darwinium: The premium currency, available through purchases but also through achievements, daily rewards, Mesozoic Valley missions and Beyond missions. Spending it on permanent boosts beats spending it on one-off speedups every time.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Primary Simulation | From your first click to well past the Singularity | Entropy, Ideas, Metabits, every species unlock |
| Mesozoic Valley | Unlocks after early Primary Simulation progress | Mutagen, dinosaur trait cards, Darwinium from missions |
| The Beyond | Unlocks later than Mesozoic Valley, runs in parallel | Stardust, planets and stars, Darwinium from missions |
| The Reality Engine | Available from your first prestige onward | Permanent Entropy and Ideas multipliers, faster subsequent runs |
| Mars | Beyond Rank 1 | Stardust generation and progress toward the outer planets |
Primary Simulation: The main tree, running from organic compounds through single cells, fish, reptiles, mammals and primates into human civilization and technology. It is the only simulation that generates Metabits, which makes it where a run's real progress lives.
Mesozoic Valley: The dinosaur simulation, tracking archosaurs through the Cretaceous-Paleogene extinction and on into modern birds. It carries its own currency, its own trait cards and its own reset in the form of an asteroid impact.
The Beyond: The astronomy simulation, opening with the Solar System and expanding into the wider universe across released episodes. Progress here is counted in celestial bodies unlocked rather than species evolved.
The Reality Engine: The prestige screen where Metabits buy permanent multipliers. Every reset routes through it, and picking which multiplier to buy first is the single most consequential decision the game asks you to make.
Mars: The fifth celestial body and fourth terrestrial planet in the Beyond, unlocked at Rank 1. It generates Stardust like every other body and links into the game's Mars survival and terraforming content.

Tips That Actually Matter
- Stop clicking the moment a generator outproduces your finger. The first hour rewards taps. Every hour after that rewards buying the next node instead, because the whole game is built around passive output.
- Prestige as soon as progress stalls. Metabits come from Entropy and Ideas production together, and a run parked on the same milestone for twenty minutes is producing nothing you could not reach faster after a reset.
- Since the November 2025 Reality Reboot, your first prestige unlocks at Ideas rather than at the Singularity. Older guides tell you to push all the way to the Singularity first, which now wastes hours of a first run.
- Spend Metabits on production multipliers before anything cosmetic or convenient. Multipliers compound across every reset, and Reality Engine upgrades are the only progress that never gets wiped.
- Feed Mesozoic Valley in the background. Mutagen carries across asteroid resets and across Primary Simulation prestiges, so every point of it you bank is permanently yours in a game where almost nothing else is.
- Drop the asteroid when Mesozoic missions stop completing. Extinction resets the dinosaur tree but keeps your traits and Mutagen, which makes the reset pure upside once you have run out of things to buy.
- Do not skip the Beyond because it feels bolted on. Its missions pay Darwinium, and Darwinium spent on permanent boosts helps the Primary Simulation you actually care about.
- Collect daily rewards and chase achievements for Darwinium. The premium currency is obtainable without spending money through daily logins, achievements and mission completions in both expansions.
- Push to Research Level 56 to open the Amphibians chapter. The Reality Reboot gated new branches of life behind research level rather than raw Entropy, which turned research into its own progress track.
- Read the entries. Every unlocked species and celestial body carries a real science write-up, and the Mesozoic trait cards work the same way. If you are playing this alongside a child, that encyclopedia is the actual reason to pick it over any other incremental.
Common Mistakes to Avoid
- Hoarding Entropy for one distant node. Idle games compound, so three cheap generators bought now will out-earn the expensive node you were saving toward long before you could afford it.
- Refusing to prestige because you will lose progress. Entropy and Ideas reset. Metabits, Reality Engine upgrades and Mutagen do not, and a post-prestige run reaches the same point in a fraction of the time.
- Spending Darwinium on temporary speedups. A time skip feels good once and then it is gone. Permanent boosts are the only Darwinium purchase that still matters two prestiges later.
- Treating Mesozoic Valley and the Beyond as optional side content. Both pay Darwinium through missions, Mesozoic Valley pays permanent Mutagen, and skipping them slows down the main tree you were trying to protect.
- Following a pre-2025 walkthrough. The Reality Reboot changed the engine, the prestige timing and the upgrade list, so anything telling you to reach the Singularity before your first reset is describing a different game.
Frequently Asked Questions
What are all the currencies?
Entropy and Ideas drive the Primary Simulation, Metabits are the prestige currency spent in the Reality Engine, Mutagen belongs to Mesozoic Valley, Stardust belongs to the Beyond, and Darwinium is the premium currency that turns up everywhere. The Reality Reboot added Knowledge as a second prestige currency alongside Metabits.
When should I do my first prestige?
Since the November 2025 Reality Reboot, prestige unlocks once you reach Ideas rather than at the Singularity. Take it when Entropy growth flattens out. The Reality Engine multipliers will carry you back past that point quickly.
Is Cell to Singularity free?
Yes, free to play with optional Darwinium purchases. Darwinium is also earned through achievements, daily rewards and missions in both Mesozoic Valley and the Beyond, so the premium track is not required to see the content.
How many simulations are there?
Three main ones: the Primary Simulation, Mesozoic Valley and the Beyond. They share only Darwinium. Each has its own currency, its own tree and its own reset mechanic.
Does the science actually hold up?
The species entries, geological eras and astronomy write-ups are built as an educational encyclopedia, and the developers lean on that as a selling point. Post-Singularity content is deliberately speculative science fiction and is presented as such.
