„Nominated for Best Mobile Game at German Computergames Award 2018" „Nominated for Best Mobile Game at German Developer Award 2018" **** Immerse yourself in the challenging world of QB - A Cube's Tale, a labyrinth puzzle game featuring innovative gameplay that will put your strategic thinking to the test. **** FREEMIUN The first 20 levels of QB - a cube's tale are now free to play. If you enjoy the game feel free to buy the full version and puzzle throw 80+ tricky levels. ---- In QB - a cube's tale, you roll through a total of 80 levels to reach each of the final black cubes. Over the course of the game, new cubes are introduced, each with their own mechanic, which make your journey more difficult. The trick of these colored cubes is: It depends on which direction you enter them. For example, one destroys the field in which you are moving. And before you know it, the goal is unattainable and the level starts again. But do not worry, you can play each level as many times as you like. For example, to find the perfect way, because then up to 3 stars are waiting for you as a reward. With the collected stars new levels are unlocked. So you can skip a level if you have been particularly successful in another. If you have collected at least 190 stars, it gets tricky: Because then you can enter the "Challenge Mode", where you have to solve a number of levels with just a single attempt. Here, your skills in 4 stages with 4 levels of difficulty will be put to the test.   Of course, your progress will be saved in the iCloud so you can continue playing on all your devices.
