So, all in all you'll be able to keep playing for free without too much hassle, and you'll have a good game experience as well. Gems can be earned by winning races, and these can be used to unlock power-ups tickets (which you need to enter a race) can be won by gaining three stars on an event or by waiting for them to refill (which takes 30 seconds) you get coins for taking part in races, which can be used to boost up your car and new levels can be unlocked by beating boss characters. Scavenging for game currency in order to unlock all this stuff isn't as much of an issue as it is in other games. There are tons of tracks, power-ups, and characters to unlock. You whizz around a series of lavishly-crafted summery tracks collecting power-ups to help you finish before the rest, while dodging crabs and seagulls.
