If there is one game that has been played by almost anyone that got close to any kind of computer, it has to be Tetris. It is everywhere: From key-chains, over mobile phones, TV set-top boxes and pocket calculators to high end PCs. Think of any platform and you can be sure this game runs on it. If there ever are refrigerators with Internet connections, you will certainly be able to stack some blocks while checking your milk re-order. Tetris is one of those rare games that have outgrown copyright struggles and has become a commonly shared idea, which massively contributed to its success. Still, under this myriad of clones and copies, there are some versions many people consider the definite version. Like Spectrum Holobyte's Tetris – which often is (wrongly) thought of as the first – and the probably most famous one, which we are going to talk about today: Tetris for Game Boy.
A quick glance at the screenshots of this game may cause some to assume that this is a digital version of the very well-known board game Othello, which is particularly popular in Japan. Unlike Othello, the present game called Spot is played exclusively on the computer. This is because the rules require a complex regrouping of the pieces for almost every move. This can be handled better virtually than with real board game equipment. At the time that the basic rules for Spot were invented, the Internet was not anywhere as widely spread as today. Therefore, the artificial intelligence became the adversary of choice. Competition between human opponents is still rather rare, in contrast to Othello.
