Crossy Road was released in 2014 by Hipster Whale, an Australian studio founded by Matt Hall and Andy Sum, and it became one of the most successful mobile games of its era almost overnight. It's a direct, voxel-art modernization of Frogger's classic "hop across traffic" formula, but built as an endless runner rather than a fixed set of screens — there's no final level, just an ever-continuing procedurally generated path of roads, rivers, and rail tracks that gets more dangerous the further you go.
Its blocky, colorful art style and huge roster of unlockable characters (from chickens to pop-culture crossover characters in later updates) helped it stand out in a crowded mobile market, and its success helped popularize the "endless hopper" as its own recognizable sub-genre.
There's no finish line — the goal is simply to survive as long as possible, going as far as you can before a car, river, or train ends your run, with your best distance serving as the score to beat next time.
It's a modern classic that proved a decades-old arcade formula still works perfectly with the right presentation. If you enjoy this kind of endless arcade challenge, GBK Games also has Subway Surfers for another beloved endless-runner icon.
