Inspired by his favorite puzzle board game, Pentominos, Pajitnov created an electronic game that let players arrange puzzle pieces in real time as they fell from the top of the playing field. The resulting design was a game that used seven distinctive geometric playing pieces, called Tetriminos, each made up of four squares connected along their sides. The seven Tetriminos are the I, O, T, S, L, Z and J. Pajitnov called this game “Tetris, ” a combination of “tetra” (the Greek word meaning “four”) and “tennis” (his favorite sport).
