About Rainbow Billy The Curse of the Leviathan

HEROES COME IN ALL COLORS.

Rainbow Billy: The Curse of the Leviathan is a wholesome, creature capture, 2.5D Adventure-Puzzle-Platformer with over 30 hours of gameplay! It is a family-friendly, openly accessible, RPG-infused adventure in which you must save whimsical creatures by bringing back color to the world you once knew!

Rainbow Billy tells a universal coming of age story about dealing with changes in the world and accepting ourselves and the others around us! Sometimes it only takes a conversation, empathy, and a new point of view to make a world of a difference.


EXPLORE A WONDROUS, EXPANSIVE WORLD!

Play over 30 hours of gameplay with dark caverns on secret islands to hidden coves off in the stormy seas. Explore a rich world filled with 85+ islands and caves, treasure, fish (because every great game has a fishing minigame!), friendship and... danger!


BEFRIEND CURIOUS CREATURES!

Collect over 60 strange, lovable creatures and help them with their problems in non-violent encounters! Create your own unique team to save the day!


SOLVE ENVIRONMENTAL PUZZLES!

Each world is filled with clever challenges and secrets that unlock new areas to explore!


RECOLOR THE WORLD!

Restore color to a monochrome world and help your friends find the courage to be their true selves in a story about empathy and growth.


How much does Rainbow Billy The Curse of the Leviathan for PC cost right now?

Rainbow Billy The Curse of the Leviathan for PC starts at €0.23 (€0.60 with fees) at Kinguin, a Steam key, which is 97% under the €17.99 (no fees) it costs on the official store.

That €0.23 (€0.60 with fees) already includes the OCTGOC10 coupon, so apply it at checkout or the store will show you a higher price.

With 14 offers across 13 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.

That puts it 71% under its average of €0.89 since 2021, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Rainbow Billy The Curse of the Leviathan now or waiting?

That €1.05 (€1.59 with fees) key is at one of its best prices.

  • Those €1.05 (€1.59 with fees) are 77% below what it usually costs, measured on the store price.
  • 9 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
  • Not counting today, the lowest we have recorded for the Steam Key across 777 days is €2.00 — and today it is below that.
At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 1,675 daily records of the Steam Key for Rainbow Billy The Curse of the Leviathan across 14 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.

Can you activate Rainbow Billy The Curse of the Leviathan in US?

12 of the 14 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Rainbow Billy The Curse of the Leviathan offer?

One listing is worth ignoring: the Steam key that Steam has at €17.99 (no fees) is more than 29 times the cheapest offer and is not what this game costs. The number to work from is €0.23 (€0.60 with fees) at Kinguin.

WHAT CAN YOU FIND ON GOCDKEYS?

You will find a price comparison in different stores for the standard PC edition of the video game Rainbow Billy The Curse of the Leviathan in Steam Key format, to make it easier for you to find the cheapest price or the best deal.

Most common FAQs when buying Rainbow Billy The Curse of the Leviathan for PC in digital format:

It is a key that will allow you to download the game Rainbow Billy The Curse of the Leviathan on your PC from official download platforms.
As of 27/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Rainbow Billy The Curse of the Leviathan on PC is €0.23 (€0.60 with fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Rainbow Billy The Curse of the Leviathan to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Rainbow Billy The Curse of the Leviathan, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.
