Every player in goalunited has a certain amount of experience, which means playing experience. And as the name suggests, players can only gain experience by playing in matches. The default experience level of each player is limited to 100, however this limit can be increased up to 110 through the special Versatility cards and the Experience boost upgrades and up to 115 if you own all 5 Legacy Towers

The more experience a player has, the more he can make of his skills. A player with 100 experience will therefore have a much higher base than a player with 20 experience, even if the individual skills are exactly the same.
Different match types give different amounts of experience. Players receive the following amount of experience per 120 minutes played (regular match plus extra time):
Competition | Amount |
League match | 0.4 |
Friendly/Training match | 0.25 |
Cup Match | 0.6 |
Qualification | 1.4 |
International Masters Group phase | 0.25 |
International Masters knockout phase | 0.8 |
Experience is given for the exact playing time that a player has been on the field. Players who have to leave the field for an injury or after receiving a red card only get the experience amount for the number of minutes they have been on the field. Players continue receiving experience from official, friendly, and practice matches until they reach their current experience limit. A limit unlock and post-match experience gain are separate events: club news may show the amount added to unlock the player's current limit, while the player profile may then show the experience earned from a match. After a future limit unlock, the player can gain experience from matches again.
