Subway Surfers

Subway Surfers is a free game by Kiloo and Sybo Games. It is a fun, free game, similar to Temple Run, reviewed here. In it, you control a variety of characters who  have been caught spray painting a subway car. To outrun the track inspector and his dog, you must run along the subway tracks, avoiding obstacles like subway cars and bushes. To unlock more characters, find or buy mystery boxes all with tokens that, if you collect enough of them, unlock new characters. Another way to unlock more characters is to collect coins that you find while running. The coins can also use to buy head starts, mystery boxes (which give you items, tokens, trophies, and coins), hover boards (which give you invincibility), and allow to skip missions. You can find various power-ups as you run, like jetpacks and coin magnets. You can purchase upgrades for these power-ups with coins. The only downside is that ads pop up from time to time. I rate it 4 stars and recommend it for ages 7 and up.
