The Beginning of It All
So you just started playing Cell to Singularity and you're thinking, "I'm already loving this game, but I'm not sure how to play." Well, I've got you covered, pal. It's pretty simple.
Cell to Singularity is an idle game. The player taps on the screen to earn points, and then uses those points to purchase upgrades. Most of the strategy in the game involves deciding what is the best way to save and spend points. The goal of the game is to move through the tree of life to learn more about evolution. The first type of points, or currency, is called Entropy. As you progress through the game, new forms of currency will unlock.
A common question early on in the game is, "How do I collect Entropy faster and more efficiently?" If you have a touch-screen device that supports multi-touch, you can use multiple fingers to tap, allowing you to earn Entropy a lot faster then with just one finger. You can also use an autoclicker if you want (and we actually recommend this method for players with motor issues, or repetitive stress injuries like carpal tunnel).
Let's say you've been buying a lot of Amino Acids, and it starts taking longer and longer to be able to afford them. If a Generator is more expensive than a single-purchase Upgrade, then you should buy those upgrades instead! Single-purchase upgrades improve the earning power of the generators, increasing the amount of points you get from tapping, and make it easier to get more points, more quickly.
Once you have purchased several Generators, set the purchase multiplier to "maximum" and wait for a while. You'll see that the total amount you can earn per second for each purchase depends upon how many of each you can buy. Depending upon the upgrades, an older Generator may earn you more than a newer one, until you get enough upgrades for the newer Generators. The "maximum" multiplier makes it easier to tell which Generators are more cost-effective.
There are two currencies in the main simulation: Entropy and Ideas. Players may choose whether to use "normal", "scientific", or "custom" notation in their game (you can choose this option from the Settings Menu). The abbreviations for the amounts in play are:
|T||Trillion||1 + 12 Zeros||1E12|
|Qa||Quadrillion||1 + 15 Zeros||1E15|
|Qi||Quintillion||1 + 18 Zeros||1E18|
|Sx||Sextillion||1 + 21 Zeros||1E21|
|Sp||Septillion||1 + 24 Zeros||1E24|
|Oc||Octillion||1 + 27 Zeros||1E27|
|No||Nonillion||1 + 30 Zeros||1E30|
|Dc||Decillion||1 + 33 Zeros||1E33|
|Udc||Undecillion||1 + 36 Zeros||1E36|
|Ddc||Duodecillion||1 + 39 Zeros||1E39|
|Tdc||Tredecillion||1 + 42 Zeros||1E42|

|Ndc||Novemdecillion||1 + 60 Zeros||1E60|
|Vg||Vigintillion||1 + 63 Zeros||1E63|
|Uvg||Unvigintillion||1 + 66 Zeros||1E66|
|Dvg||Duovigintillion||1 + 69 Zeros||1E69|
|Tvg||Tresvigintillion||1 + 72 Zeros||1E72|
|qvg||Quattorvigintillion||1 + 75 Zeros||1E75|
A note for international players: Cell To Singularity uses "Short Scale" notation, as in the above table. Short Scale is primarily used in the US, Canada, Great Britain, Australia, and Eastern Europe. C2S does not use "Long Scale" (primarily used in French Canada, Western & Central Europe). You can tell whether you are using short or long scale by what you call the number 1,000,000,000 -- if you call it "billion" you use Short Scale and if you call it "milliard" you are using Long Scale.
So you've finally evolved life to include apes and humans - and with these new creatures comes new, more advanced brains! At this point, you have to tap on the big brain icon, which is found in the evolution tree near where you first upgraded the brain. This will begin production of a new currency called Ideas. After you've earned enough points and upgraded the Generators that produce Ideas, you will be able to automate both Entropy and Idea production.
When you've been playing the game for a while, eventually you'll reach an upgrade called the Singularity. Once you purchase this Generator, all of a sudden your simulation crashes and you have to restart from the beginning again! What happened?!
Don't fear, it's nothing dangerous, and nothing has gone horribly wrong with your game. This is the start of a new journey, where you'll start building up a prestige currency known as Metabits. Metabits are used to upgrade your Reality Engine, the computer system running the simulation. They also boost your Production Multiplier, which helps you produce Entropy and Ideas at a much quicker rate, which in turn helps your Metabits build up even more quickly.
You're probably wondering, "Does the Singularity reset my simulation again when I reach it a second time?" The answer to that is NO. While rebooting the simulation allows you to spend your earned Metabits to purchase upgrades for the simulation, all reboots after the first one are voluntary. To do this, you just have to click the bar that is under your currency counter and bam, you've reached the Reality Engine. There's a huge reboot button and a stats page that you can access if you click the little graph icon in the top left.
Where’s the dinosaur simulation?
You can find the Mesozoic Valley, the game's dinosaur expansion, by going to your evolution tree and looking at the screen just to the right of the Tetrapod Generator. You'll see a Mysterious Rock that needs to be tapped repeatedly to be opened; after you've unlocked it you can access the new simulation any time via that part of the evolution tree or, much more quickly, by clicking the green dinosaur skull button in the top right of the screen. You need to unlock Flatworms to access the Mysterious Rock.
Why aren't my dinosaurs making money by themselves?
How do I upgrade my fossils-per-tap?
Fossils-per-tap can be upgraded by certain rare trait card. More info on trait cards can be found in the Trait Cards section.
Does rebooting your main simulation reset the Mesozoic Valley?
Rebooting your main simulation has no effect on the Mesozoic Valley, and vice versa; they are completely separate and individual simulations. However, resetting a Mesozoic Valley simulation will unlock the next rank of the Mesozoic Valley, and each rank in Mesozoic Valley makes the main simulation 2% faster.
Why do the reptiles/birds on the main simulation tree look dark and glitchy?
Well... that's because you haven't reached the right rank yet in the Mesozoic Valley to unlock them. Make sure that you've also purchased the Egg Shell and Cold-Blooded upgrades to the right of the Tetrapod Generator on the Main Tree.
What’s the maximum rank in Mesozoic Valley?
Level 50 is the highest rank, after which you have to prestige.
How do you prestige and what's the maximum prestige level?
You can prestige by clicking "Prestige" at the top of the window.
The current highest prestige level is 50.
