About Strings Theory

Strings Theory is a wacky puzzle / arcade game where you control the particles of life itself!

Inspired by the romantic side of physics, we take you on an epic journey into the heart of Anomaly. Control three unlikely heroes with their own personalities and skills. Beat more than 50 brain-twisting levels. Save the microcosm from a deadly threat!


"Oh, what a beautiful mystery this land is. How inorganic." - Isaac, the smart string

Find yourself in a strange land. It's the Anomaly, where forces unknown converge. Swap between your strings and use their unique skills to avoid the dangers. Collect the quanta of energy, and reach the wormhole to the next level.

Play with friends! Strings Theory supports up to 3-player local co-op. Enjoy a mode where every player controls a different string in front of a single screen. There's a twist: only one string can move at any given time, so you have to talk about your strategy and solve the puzzles together!


Deatomizers that can evaporate you in an instant. Trapdoors to the void of space. Gravitiles that change gravity. The ever-moving Kinetiles, and more.

You're going to need brains to navigate such a treacherous space. A bit of good old arcade timing won't hurt either.


Telly, Isaac, and the Twins used to be your everyday strings. Sucked into the Anomaly, they're our only hope to stop the impending doom.

    Telly is a hot-headed wannabe hero. What he lacks in brains, he makes up for in strength. Use him to push obstacles out of your way.

    Isaac is a mysterious chap with a keen interest in physics. Make him phase through floors to reach unreachable places.

    Twins, or Norm and Sal, are like the poles of a magnet. Separate them, and they'll be more than happy to conjoin.

Can this odd bunch get together and save the world? Yes, but only if you help them!

How much does Strings Theory for PC cost right now?

Strings Theory for PC starts at €8.10 (€8.66 with fees) at Key4Games, 31% under the €12.49 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €12.49 (no fees) at Steam.

That €8.10 (€8.66 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.

Only 3 offers across 3 stores carry it, and thin supply means the price barely moves.

Worked out from 356 daily records of the Steam Key for Strings Theory across 1 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Are these stores safe to buy Strings Theory from?

One caveat worth €0.29 (€0.11 with fees): the €8.10 (€8.66 with fees) at Key4Games is the cheapest, but that store carries only 37 Trustpilot reviews, so there is barely any track record behind it. Difmark sells the same shared account for €8.39 (€8.77 with fees) — €0.29 (€0.11 with fees) more — backed by 14.2k reviews and a 4.1 out of 5, which is a small premium for a seller thousands of buyers have already tested.

Which Strings Theory format should you buy?

With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.

The key at Steam costs €4.39 (€3.83 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.

Can you activate Strings Theory in US?

All 3 offers are Global, so the code redeems on any account no matter where it was created.
