0xUniverse: Dominate Space & Earn Collectibles



0xUniverse is a browser-based space exploration game from 0x Games. It features planets and spaceships that are digital collectibles on the Ethereum blockchain.

We took some time to try out the game, and this article will explain what we found out. We'll tell you all about the essential features of 0xUniverse, including buying planets, building spaceships, gathering resources, and exploring to find new planets.

Most importantly, we'll weigh in on the topic of whether 0xUniverse is a fun game – and what types of players may enjoy it more than others. If you've wondered what 0xUniverse is all about, read on to find out.

0xUniverse storyline

0xUniverse takes place in the 22nd Century. New developments in spaceflight have made it possible for human beings to travel to distant star systems.

The United Earth Government has undertaken missions to discover and colonize habitable planets, and it has had some success.

But it now wants to private this process and put it into the hands of entrepreneurs.

For this reason, it is selling off planets that have already been discovered. It has also passed a law that guarantees ownership to any entrepreneur who discovers and settles a planet.

As the owner of a space exploration business, it is your job to collect resources, build ships, and explore the Universe in search of new planets.

Your business will start off small. But with hard work, you hope to build a space-faring empire that will be envied by all of humanity.

Registration process

Registration for 0xUniverse is simple. First, navigate to the official 0xUniverse website. Then click the big, red button that says play now.

blockchain galaxy

It will take a minute or two for the game to load. Once it does, click the registration icon in the upper-right corner.

register your account

You'll need an wallet to hold your planets and spaceships in. For most players, we recommend Metamask. It stores the private key on your device, maximizing the security of your assets.

If you are a beginner to cryptocurrencies and don't want to be responsible for storing your private key, you can use Arcane instead.

Arcane stores your private key in the cloud. This makes for a simpler installation process, but this convenience comes at the cost of security.

It's always possible that a hacker could steal a private key that is stored in the cloud. So we only recommend using Arcane if you have a small collection and convenience is extremely important to you.

Once the wallet selection page appears, click the select button below the type of wallet you want to use.

wallet selection - Metamask or Arkane

If you chose as your wallet, a popup box will appear asking you to confirm.


Click connect, followed by sign to link your wallet. The game will ask for your email address and a screen name for you to be known by.

Fill out the information and click submit.

That's all there is to registering for 0xUniverse.

As you progress in the game, you should be able to discover planets and harvest their resources. But to begin with, you'll need to buy a planet from the United Earth Government (UEG).

To buy a planet, click the planets button in the top-left corner.

planet store

Click the for sale tab in the top-right corner. You'll see a list of planets available for purchase.

planets for sale

Prices range from 0.004 ETH (around $1.21) to 0.015 ETH (around $4.55). They are all relatively inexpensive, so it doesn't take much of an investment to begin playing.

Knowledge and population

Once you've got a planet, your colonists will automatically begin gaining knowledge. 1 unit of knowledge will be produced per person, per hour.

The higher your population, the faster your knowledge will grow.

Your planet's population will grow over time. The more planets you have, the more your population will grow.

So if you want more knowledge, you need to colonize as many planets as you can.

Inventing space ships

Click the spaceships button to see if you have enough knowledge to invent a new ship.


If you have enough knowledge, the invent a spaceship button will be available. If there is no button, it means you need to wait a few minutes for more knowledge to be accumulated.

Push invent a spaceship to get started designing your first ship.

The developer doesn't charge for inventing.

But it will cost around $0.10 worth of ETH or more to pay for the gas costs associated with recording the transaction on the blockchain.

Once the transaction has gone through, your spaceships tab will show the words “inventing a spaceship” where the button was previously.

It will take a few minutes for your colonists to finish inventing the spaceship. When they are done, it will appear in your collection.

Collecting resources

As soon as you own a planet, your colonists will start collecting resources.

There are 20 different resources in the game. They are classified into four rarities: common, rare, epic, and legendary.

The kind of resources you can collect depends upon which planets you own. Here is a complete list of resources in 0xUniverse:


  • Lead
  • Mercury
  • Tungsten
  • Zinc
  • Copper
  • Tin
  • Iron
  • Aluminum
  • Quartz
  • Nickel


  • Ruby
  • Sapphire
  • Silver
  • Platinum
  • Gold
  • Emerald
  • Uranium


  • Plutonium
  • Tritium
  • Californium
  • Titanium
  • Iridium
  • Diamond


  • RedMercury
  • Adamantium
  • Kryptonite
  • Unobtanium
  • Neutronium
  • Mithril

In 0xUniverse, resources can be transported from one planet to another at no cost. So the best way to obtain resources is to have as many planets as possible, preferably with many of them producing epic or legendary resources.

Shipbuilding and ship missions

Below your ship model, the population and resources needed to build it will be displayed.


When you have enough resources to build the ship, a build & launch button will appear. Push this button to build the ship and send it on its first mission.

In our testing, we found that it could take up to a day or longer to get enough resources to build the first ship.

Once you push the button, you'll be shown a map of the galaxy.

Sectors and map options

The galaxy is divided into “sectors.” The brighter the sector is, the greater the number of planets that have been discovered in that area.

The darker the sector is, the smaller the number of planets discovered.

There are two checkboxes at the bottom-left that control how the map is displayed. By default, hide planets with lack of resources and hide planets for rent are unchecked.

This is because you can choose to rent the planets of others to use as launching pads instead of launching from your own planet.

However, this option is expensive. So most beginning players will want to launch from their own planets.

To change the map so that it only displays the sector with your own planet in it, check both hide planets with lack of resources and hide planets for rent.

This will cause all of the sectors to turn dark except for the one your planet is in.

sector selection

If the sector containing your planet is not shown, it may be behind the text at the top of the screen. In this case, left-click and drag to rotate the map until your sector appears.

Selecting your planet as a launching point

Once you've got your sector in view, left-click to open the list of planets you own within that sector.

launching point

Press the select button below your planet. This will open the launch confirmation screen. Then press launch to launch your new ship.

It will cost $0.64 or more in ETH gas fees to launch the ship.

launch ship

While the transaction is processing, the display underneath your ship will read “searching for a planet.”

When it is finished, you'll get a response saying either that you have discovered a new planet or that the mission has failed.

If the mission fails, you will lose the ship, along with all of the population that was used for that mission. Space exploration is a grim business.

mission failed

If you try to build a second ship of the same model as the last one, it will cost 150% more resources than the previous one did.

This means you will have to wait longer before starting the next mission.

However, you can avoid this problem by simply inventing a new ship model.

Aside from gas fees and time, there is no further cost to sending ships on missions. You can play 0xUniverse for as long as you want with just one planet – although buying or renting more planets will allow you to progress faster.

Leasing and selling planets in 0xUniverse

Once you've discovered a few planets, you can rent them out to other explorers for a fee or even permanently sell them to other players.


To lease your planet out, Just click the planets tab in the upper-left corner of the main menu. Then click the particular planet you want to lease out.

The planet's info page will open.

leasing planets

Click rent to put the planet up for leasing. Enter the price you are willing to lease it out for, and then click set rent price.

rent planet

It will cost a few pennies worth of ETH or more in gas fees to offer your planet for leasing.


If you have decided to quit 0xUniverse, or if you just want to sell your planet for any reason, you can put your planet up for auction. Just click sell from within your planet's info page.

Enter your planet's starting (max) price, ending (minimum) price, and the number of days you want to keep it up for auction.

Then click start auction. The price will begin at max and slowly decline until a buyer is found or time runs out.

Building a space-faring empire in 0xUniverse

Once you've begun to acquire planets and lease or sell them to others, you can start building your space-faring empire in 0xUniverse.

Use the ETH you earn from renting out your planets to buy new ones. Then use the resources from these planets to build new ships and find even more planets to add to your collection.

But be careful. Everything in 0xUniverse costs resources. And these resources can only be gathered over time.

Making the wrong decisions may be the difference between reaching your goals in a few months vs. taking years to do it.

If you're willing to invest a lot of ETH up front, you could also just skip the whole game and buy another person's space-faring empire.

But this might not be as fun as starting from scratch.

Corporations in 0xUniverse

Players who want to join with others for mutual benefit can become shareholders in corporations. There are currently three corporations: Forge, Eternity, and Dominion.

Shareholders have the right to vote in elections for the corporation's leader (CEO).

Any shareholder with more than 5% of shares can nominate a candidate and initiate a vote. Shareholders with less than 5% cannot initiate a vote, but can vote in elections initiated by others.

The voting lasts for 14 days or less. If the new candidate fails to attain at least 50.01% of the vote, the current leader stays in place.

The leader of a corporation has the right to decide when and whether to pay out ETH dividends to shareholders based on the profits the company made from selling or renting out planets.

But these dividends are distributed proportionate to the shares owned by a player.

Under the current rules, the leader does not receive any compensation from the corporation for his “labor” in directing the corporation's assets.

Future 0xUniverse features: Extra-galactic exploration, logistics, and war

In the future, the developer plans to allow players to explore outside of the current galaxy and to engage in war.

In its description of these features, the developer has stated that exploration will require “production and logistics” and that “corporations will be able to control the sectors of the galaxy and earn income from them” in the future.

In other blockchain-backed space exploration games, such as Crypto Space Commander and Space Misfits, players are required to create logistical operations to move resources from one place to another.

They must build ships to move minerals, not just to discover new planets.

In these games, there are also some areas that are “fringe” or “lawless.” These areas are too far away from the government's power for it to be able to protect explorers.

As a result, players have the ability to engage in space piracy if they want.

But players who don't want to engage in this activity can play the entire game in “lawful” areas if they desire.

Based on the 0xUniverse team's description of future features, it may be that they are planning to make future maps play more like these other games, although 0xUniverse will probably still retain its uniqueness in some ways.

Regardless, current planets are held on the Ethereum blockchain under a smart contract.

So players do not need to worry about losing their current planets to pirates in the future or having to develop logistics to transport materials on the current map.

Is 0xUniverse fun?

In an attempt to understand what type of players may enjoy 0xUniverse, we played it for a short time.

We bought a planet, invented a spaceship, collected resources, and sent it on one mission.

We found the game to be very compelling. The ability to invest only a few dollars worth of ETH for a chance at finding a rare planet is hard to resist.

Add in the fact that the player can essentially perform an unlimited number of missions for this small investment, and you've got a recipe for endless entertainment.

But having said this, we do need to point out that some players will not like this game. 0xUniverse is what could be called a “casual” game. It takes very little time to play.

Usually, a player can succeed at 0xUniverse by spending no more than a few minutes a day performing a few actions.

So if you're the kind of player who wants a game to take up many hours of your life, you may be disappointed by 0xUniverse.

You also may be disappointed by 0xUniverse if you prefer to play the latest graphics-intensive blockchain games, such as Gods Unchained or The Six Dragons.

0xUniverse has simple graphics and a browser-based UI. It will run on practically any machine, and it isn't made to show off the qualities of a high-end rig.

Having said this, we think many players will find 0xUniverse to be a very fun game. The game's progression occurs over an extremely long time.

So you can enjoy checking on it every day, even though it only takes a few minutes each day to do so.

But don't take our word for it, check it out for yourself. And if you like it, consider browsing through the list of planets at OpenSea.
