Managing my games after publication

Can I upload my game to other portals?

Yes, absolutely. You can upload your game to any other portal. If you like you can also choose to offer the game exclusively on CrazyGames in exchange for a 50% increase in revenue share. You can read more about this subject in article 5.3 of our Terms & Conditions.

Can I update my game? How?

Yes, you can update your game through your developer account. Only replace the current files and send them again for approval.

How is the ranking of the games calculated?

We use a popularity based ranking system. The system tries to rank games in such a way that players can easily find the best games. We also take into account factors that stimulate fair competition among different games. That is for example why new games get a boost. In general, it is all about users' engagement stats, for example, play counts, average playtime, return rate, popularity, votes, etc. Each of them contributes to the overall ranking (if all of them is higher, then it is more likely that the game will rank better). What is important to know is that we don't offer "pay-to-feature" options. At CrazyGames we believe that the players know best, that is why our ranking system is based only on player statistics. This makes our platform entirely different from others. If you want to know more about this subject, read article 5.1 of our Terms & Conditions.

Will my game appear on the homepage of CrazyGames?

Yes. Every new game submitted through the Developer Portal gets a fair shot by being guaranteed 48 hours on the homepage*. We do this to stimulate fair competition among different games. After the initial 48 hours, your game still gets a bonus for the next 6 days. Whether the game stays on the homepage depends on its popularity and user engagement ( session duration, return rate, ratings, ...). Assuming no excessive submissions are made, the game is not low-quality, and the game contains no external advertisements.

Earning money with my games

Will I earn money by publishing my game?

Yes, if the game satisfies the following conditions:

  • The game doesn't contain branding from another games portal.
  • The game doesn't contain external advertisements.
  • The game and its total assets must maintain a level of originality that make it distinguishable from existing games.
  • The game integrates the CrazyGames SDK.

If you want to know more about these conditions, read article 5.3 of our Terms & Conditions.

Can I choose any ad provider for my game?

No, we provide our SDK for in-game advertisements. Check out the SDK page for details. We currently offer an SDK for Unity WebGL, HTML, and JavaScript games.

My game is published on Steam, Google Play store, Apple App Store or Facebook, is it still eligible for revenue share?

Yes, you can read article 5.3 of our Terms & Conditions.

How much will I earn?

It depends on the popularity of the game, the engagement rate, and the interest of advertisers. Integrating our SDK and ads inside the game will greatly affect how much you'll earn. If you'd like to know more about this subject, you can read article 5.4 of our Terms & Conditions.

How can I increase my revenue?

We offer a time-based exclusivity option that will increase your revenue share by 50%! If you would like to receive this 50% increase, you have to accept the following conditions.

  • You should make the game exclusively available on CrazyGames for two months following the release date. (You can still distribute the game on Steam, Apple App Store, Google Play Store, and Facebook.)
  • You should implement the SDK, including in-game advertisements.
  • You need to allow CrazyGames to distribute your game to other portals. The revenue earned on websites of distribution partners will, of course, be shared with you.

Note that by default your revenue share is reduced to the standard share after the two months exclusivity period. Then you are free to upload your game to other portals.

You can ask us to extend the exclusivity period by emailing us.

The correct ad placement plays a crucial role in your game's revenue. You can take a look at our advertisement guidelines for tips. After your game reaches 50k plays, we also provide personal advertisement advice.

How will I be paid?

The payout is monthly with a minimum of 80 euros. If the revenue doesn't reach 80 euros in a month, it's carried over to the next month. We pay via wire transfer or Paypal. If you want to know more about this subject, read article 5.6 and 6 of our Terms & Conditions.

Making games

Do I need to learn coding to make web games?

If you want to make awesome games, knowing how to program will make life much easier. Most of the games on our site use Unity, Phaser, or other game development frameworks that require coding knowledge. However, game engines like GDevelop give players the option to make games without learning code.
