During the game, two of the possible rewards are infinite lives and infinite boosters. Unlike regular lives and boosters, these bonuses allow you to use unlimited lives and boosters for the time allotted.
Please note that the timers for infinite bonuses in the game cannot be paused. Both earned and purchased bonuses work in the same way. In effect, what you get is not an item that you can use at any time but the opportunity to use bonuses an unlimited number of times within the specified time period (for example, the subsequent two hours), starting from the moment when you receive the opportunity. Please bear in mind that even if you leave the game, the timer for infinite bonuses will continue to count down.
