Alto's Adventure & Alto's Odyssey
Alto's Adventure & Alto's Odyssey are two super fun games that are easy to pick up, but challenging enough to keep you coming back. Like most of the games on this list each session only takes a few minutes, so it is perfect when you only have a little bit of time. But, I like that when i have 20 to 30 minutes I can play and play and play these two games.
You control Alto, who is snowboarding or sand-boarding depending on the game. From there you need to jump over obstacles, chain together tricks and keep going. It's basically an endless runner style game on a board. It's beautiful and has a great soundtrack if you are able to put headphones in.
Alto's Odyssey - $4.99 on iPhone, Coming Soon on Android
