It is possible to use special tickets unlimited times using Titanium backup. To do that do following steps:
- when have full team tickets or many special tickets make a full backup of hill climb racing 2 (open Titanium backup, GO to backup/restore tab, search hill, select game and press backup)
- after succesful backup, you can enter în game and use special tickets or team event tickets
- after using all tickets fully close game, reopen Titanium backup, search for hcr2, press restore and select data only
- now open the game and make few taps in loading screen, after few seconds you'll be asked what progress save you want to use, select local
- you'll have back all tickets used earlier.
Don't forget to make constant backups after wining new tickets. After playng team event races restore data to get your tickets back.
