Subway Surfers is a run-forward game in the style of Temple Run. You have to leap over obstacles, slide under barriers, and see how far you can get.

The controls are easy enough that a child can master it quickly, while the game is involving enough to maintain your attention for quite a while. You have three channels to run in - left, right, and center. As you hop from channel to channel, you have to jump and duck. To add a challenge, there are subway trains coming at you to avoid. You can get on top of them and then leap from one to the other, gathering coins. There are also special power-up items and collectibles to go after as well.

If that wasn't tricky enough, you're also being chased from behind!

This is the perfect time filler game. You're waiting in line for the bus and do a couple of runs. Later on in the day you do a few runs while waiting for the doctor. Over time you earn new characters, new abilities, and bragging rights to your friends and family.

Like many other social games, the game lets you pit your scores against other people you know, to see who can do the best. It motivates you to play for just a while longer to out-do them.

There are also special daily challenges, which keeps you coming back each day to do the next one.

The game itself is free, but be warned that the game has ads which pop up fairly often in the menu system. Also, the game tries to lure you into spending real money to upgrade and get new items. If you're a parent you can turn that off so that your kids don't run up your credit card bill.

Sure, the game isn't complex or epic. You're not solving the world's nuclear problems or designing a new rocket ship. But that's OK. Sometimes games are fine to be quick, relaxing, and a way to burn off energy. And, heck, you're building hand-eye coordination here as well as the ability to focus and concentrate. Those are both great areas to work on each day.

Well recommended for all ages. The game is easy to learn, fun to play, and all around enjoyable.
