An unfriendly randomizer like in NES Tetris can ruin your game, or more likely, your mood to play. The clumsy 7-bag is unnatural feeling, but allows for many building strategies to be consistently viable. It's hard to pin point it, but TGM3’s randomizer does feel more predictable, and less challenging. If youve been playing Tetris for a while, you might find that every time you close your eyes you see the Tetris pieces outlined in the darkness, just like. Truly Pseudo Randomįunction * random ( ) Pseudo random number generators try to mimic real randomness, but don’t have the properties required to deal out 70,000 Z-pieces in a row. This however can not happen in a real game, as computers don’t use true random number generators. While an unbiased randomizer offers the greatest pure puzzle challenge to players, it is unstable, and can actually result in an unbeatable sequence (PDF). We’ll see how the designers of Tetris games tried to solve these problems in a little bit. With an unbiased randomizer, there are situations where the player receives a sequence of the same piece (called floods) or a sequence omitting a certain piece (called a drought). No opinion to which piece should come next, just pick one and give it to the player.
The first and original version of Tetris released had an unbiased randomizer. I’ve curated a list of ones that I believed to be important and show how the state of Tetris has changed over the years. Several of them have been reversed engineered and documented. Over the years, the rules of how pieces are chosen has evolved, affecting gameplay and actual randomness. In Tetris, a randomizer is a function which returns a randomly chosen piece. Varying in game modes, rules, and implementations, they all play slightly-or very-differently. Since then, over 150 licensed versions of Tetris games have been released. This fun and highly addictive game challenged players to fit pieces together that were dealt in a random order. In 1985, Alexey Pajitnov and Vadim Gerasimov released Tetris to the public.
