# Secondary Currency (Engagement)

The player will gain a secondary currency (non crypto) for his engagement with the game. This means the more he drives, the more currency he get (again, higher-tier Tuk-Tuks driving on higher-tier tracks and challenge modes will grant more). Engagement levels the general player account and is a prerequisite to unlock higher Tuk-Tuk levels and play modes–for this purpose, it can be grinded or also be bought at the shop.<br>
