Don't bother. – Chug Patrol: Ready to Rescue ~ Chuggington Book Review

You get 3 levels for free and then you have to pay 4.99 to unlock the rest of the game. You get a total of 10 levels for that 4.99!! My kids ripped through those levels in about 7-8 minutes. The boys really wanted to buy the remaining levels. I said they could if they paid me the $5. They did and have now learned a valuable life lesson in how not to get cheated by advertising and marketing.
