The idea behind Glass Tower 2 is a simple one. Presented with a selection of red and blue blocks, your aim is to break all of the blue blocks without losing and red ones off the screen. Sounds easy enough. However, the arrangement of the blocks means that in order to prevent red block from disappearing off the screen, you need to think carefully about which order blue blocks should be removed in.

With 25 levels to play through in the free version of the game, there’s plenty to keep you occupied. Each level can be completed without necessarily having to save all of the red blocks, so even when you have worked your way to the end there is still the opportunity to aim for a new highscore.

Thanks to the inclusion of a realistic physics engine, the same level can be played in different ways. Removing blocks in a different order or with slightly different timing can mean the difference between success and failure.

With bonuses available and an increasing level of difficulty, coupled with a few surprises along the way, Glass Tower is a perfect pick-up-and-play game. Your progress is saved so you can pick up from where you left off without the need to start from scratch every time you launch the game.
