Thumb Moto Race is a game in which you can play as a motorbike driver and take on the challenge of riding on tracks with a lot of obstacles. The gameplay is similar to that of a traditional motorcycle race, but with a few key differences.
The most obvious of these is the fact that you can control your bike with the thumb, and that you will have to take your bike to the finish line while performing various tricks and stunts.
Another difference is that you will be able to use your bike to perform various tricks and stunts on the track, such as spinning, jumping, and crashing.
In addition to these, you will have to consider the fact that the tracks are not always flat, but have various different slopes and obstacles. You will therefore have to use your bike to navigate through the different paths and obstacles.
