Crossy Road 

Crossy Road is as simple as it gets: you tap to hop forward and swipe sideways to dodge cars, trains, and even fish. All while trying not to become a feathery roadkill. All its controls work perfectly with one thumb, and the runs are short enough to squeeze in a game or two during your daily commute.

The game’s goofy characters and endless unlocks are part of Crossy Road’s charm. You may tire of it quickly if you want something more complicated, but there are hundreds of animals and strange creatures to collect, each with little visual quirks that will keep the game interesting for a long time. 

With all of that said, the game can be pretty addictive. It’s dangerously easy to keep chasing a new high score while you tell yourself you’re absolutely going to stop after this attempt.
