TTR is really a lot of fun. The career and game modes are extensive, the graphics look (on the LG G Flex) from great and there are numerous vehicles and components to buy. The vehicles range from VW Bully, Willys Jeep. Nissan Skyline, Chevy Camaro up to the Bugatti Veyron or Lamborghini Veneno. However, the latter are quite expensive, so you need a lot of patience to make the necessary in-game coins or you can use the slightly more expensive in-game purchases.
The races will take place (forwards and backwards) on 8 different routes. Although these are relatively short, but graphically designed top. A few more lines would be desirable, however, to make the game a bit more varied.
But this is whining at a high level. TTR is super motivating and have repeatedly in between for a round. For 0.89 EUR a strong buy recommendation.
