Tetris
Ngo-1985, u-Alexey Pazhitnov wasungula iTetris njengenxalenye yeprojekthi yesayensi kwiYunivesithi yeSayensi eMoscow. Igama elithi Tetris lisuselwe kwigama lesiGrike elithi ‘Tetra’ elimele ezine - njengoko zonke iziqwenga zomdlalo zenziwe ngeebhloko ezine.
Zisixhenxe ii-tetrominoes ezinikezelwe ngokungacwangciswanga okanye iitetrads-iimilo ezenziwe ngeebhloko ezine nganye-ziwela ebaleni lokudlala. Injongo yomdlalo kukusebenzisa ezi tetromino ngenjongo yokudala umgca othe tye weebhloko ngaphandle kwezikhewu. Xa umgca onjalo wenziwe, uyanyamalala, kwaye iibhloko ezingasentla (ukuba zikhona) ziyawa. Njengokuba umdlalo uqhubeka, ii-tetromino ziwa ngokukhawuleza, kwaye umdlalo uphela xa ingqokelela yeeTetrominoes ifikelela phezulu ebaleni lokudlala.
Ezi zi-tetrominoes zisixhenxe zinikezelweyo kwiTetris kubhekiswa kuzo njengam, T, O, L, J, S, no-Z. Mna, L, kunye noJ ndiyakwazi ukucima kathathu. Kuphela i-tetromino inesakhono sokucoca imigca emine ngaxeshanye, kwaye oku kucace kubhekiswa kuko njenge ‘tetris.’ (Oku kungohluka ngokuxhomekeka kwimithetho ejikelezayo kunye nembuyekezo yokuphunyezwa kweTetris nganye; Umzekelo, kwimithetho yeTetris Worlds esetyenziswe kulwenziwo lwamva nje, iimeko ezithile ezinqabileyo zivumela i-T, S kunye ne-Z ukuba ‘zibambe’ kwiindawo ezixineneyo, Ukucoca kathathu.)
Kukholelwa ukuba yeyona midlalo ithengisa kakhulu ngalo lonke ixesha, ubukhulu becala ngenxa yokufumaneka kwayo ngamaqonga. I-Tetris ibonakalisiwe kwiiArcade, izixhobo zemidlalo yeselfowuni ezinjengeNintendo’s Game Boy, iifowuni eziphathwayo, ii-PDAs, iikhompyuter zakho kunye newebhu.
Umculo wohlobo loqobo loMdlalo woMfana oTetris obizwa ngokuba ‘nguMculo A’ uye waziwa kakhulu. Yinyani ingoma yaseRussia ebizwa ngokuba yi ‘Korobeyniki’. Kude kube namhla kuqikelelwa ukuba ababini kuthi abadala abathathu abahlala e-US bachonga ingoma ‘yiTetris tune’.
I-Tetris luphawu lwentengiso olubhalisiweyo lwe-Tetris Company LLC, kodwa umdlalo ngokwawo awunamalungelo okushicilela e-US (imidlalo ayinakuba nelungelo lokushicilela, lilungelo elilodwa elilodwa lomenzi wechiza, kwaye naliphi na ibango le-Patent ku-Tetris liza kuphelelwa lixesha namhlanje) - yiyo loo nto uninzi lweetetris lusebenza ngokusemthethweni zikhona.
