The slate of Windows Phone 8 games got a new addition as of yesterday: Marble Rush Gems. The free game has a very simple concept: you have to navigate a small marble through challenging levels filled with various obstacles by tilting and turning your phone.
As you progress you’ll gather Gems, the in-game currency. Using the Gems you can buy power-ups and even buy yourself out of an exceedingly difficult level. The levels contain various elements to make progression harder, such as lava, rocks, roads and waterfalls. By the looks of it, Marble Rush Gems has the necessary traits of a successful time-waster: simple controls, difficult game-play and boosts to help you when you’re stuck so you won’t feel despair and stop playing.
You can download Marble Rush Gems from the Windows Phone app store.
