Stacking blocks in a skillful manner, which is supposed to be a challenge? Why should you be fascinated by this game? Because it has already done so with many before you and maybe it can do so in your case as well. And the glory of Tetris remains unchallenged to this day. A variety of Tetris variants is available on the internet, which know to inspire. Because you have to again and again outdo yourself and thus improve upon your own performance. Tetris games are usually designed in a very simple way, so you can concentrate on the blocks. This is also the case at Tetrix. Here you have a small screen, on which the blocks are falling. The different forms are now to be joined together in such a way as to make for a complete row. Once you have played Tetrix for a little while, you will soon know the shapes of the blocks, which were modeled on letters, and can therefore improve your game play. At the top, the next block is always displayed to you, so that a little advance planning becomes possible. You are also given the opportunity here to leave a gap for a certain block in order to then immediately achieve several rows at a time and therefore collect more points. The risk is that you do not know just when this block will be coming and it is not so simple to always keep the gap open. Surely you can figure out the tricks of this game quickly. You take control via the keyboard, in particular with the arrow keys. With higher levels, the speed also becomes much faster which makes you constantly face new challenges. How long will you survive in Tetrix without having the blocks touch the ceiling?
