Retro Let's Play for early May 2018: Tetris Originally developed by Russian AI research programmer Alexey Pajitnov in 1984. "Tetris" has a fascinating history of rights, licensing and publishing due to a lot of complexities around the then communist USSR, and some rather shady agreements within a fledgling video games industry. As a result of both it's popularity, simplicity to port, and wide distribution, the game was ported to hundreds of devices and systems. HG101's top 47,858 games (which we're following for our list of "Let's Play" games) recently reviewed the Gameboy version (which many consider the original Gameboy's "killer app"), and ranked it number 1 in their list. However for our Let's Play this month, we'll play and talk about any port, platform of version, official or otherwise. The word "Tetris" comes from a combination of the Greek word "tetra" (meaning "four"), and Patjinov's favourite sport, tennis. The game consists of "tetriminos" - the entire set of shapes that can be made by putting four squares together with a minimum of one entire side touching another square - falling from the top of the screen to the bottom. The player must arrange these to minimise empty space. On completion of a complete horizontal line of squares, that line is erased, and the gameplay can continue. Making a complete 4-line set in a single move is called "a Tetris", and earns the player more points. The gameplay can be level based, or run in an "endless mode". The game itself is simple, but addictive, which has led it to be the highest selling video game of all time, with an estimated 170 million sales since release: https://en.wikipedia.org/wiki/List_of_best-selling_video_games The history of Tetris and it's publishing, licensing and distribution is complex. To avoid a lengthy post, I'll link to a far more detailed documentary on the game's history: Obtaining a version of the game to play is trivial. Archive.org has countless versions available for download and play in browser: https://archive.org/search.php?query=tetris The second version ever made (and the first version available outside of Russia) was for PC running on MS-DOS, and can be played in your browser here (note, you need a numeric keypad to control it sensibly): https://archive.org/details/msdos_Tetris_1986 And either an in-browser or download option here: https://www.myabandonware.com/game/tetris-1sp And the current rights holder, The Tetris Company, even lets you play it on their website for free: https://tetris.com/play-tetris Be sure to share with us your Tetris memories, whether they be your first exposure to it, or your favourite version. And of course, if you ever think you're pretty good at the game, try "Tetris: The Grand Master" by Arika. Remember that if you ever finish the game, you have to play it in "invisible mode" during the game's credits.
