Wordtris, stylized as WORDTЯIS, is a Tetris offshoot designed by Alexey Pajitnov and published by Spectrum Holobyte in 1991 for the IBM PC platform. The game was later released for the Game Boy (ported by Realtime Associates) and Super NES in 1992. In the Super NES version, players advance from levels "A" to "J." There is no level after "J." The background pictures (except the title screen) were taken from an earlier Tetris game by Spectrum Holobyte known as Super Tetris. The in-game music is composed by Paul Mogg who did the DOS version of Super Tetris with Ed Bogas.
