The collector is a LEGENDARY card!
It's a utility building that once placed in your park will gather all the Coins generated by the rides in its range. With this help, you can collect only one building instead of many! Less tapping, more time to build and take care of your park!
Note that the Collector works only when you are playing the game. Your rides will still break and lose their Coins if you leave them unattended for too long.
You can find Collectors in normal card packs, but you need a lot of luck. If you subscribe to be a VIP, you will automatically receive a legendary card every month, one of them could be a collector!
