IQ-Block
IQ方块
IQ-Block is a puzzle arcade game developed by IGS and released in 1993. Players manipulate falling blocks of various shapes, arranging them to complete horizontal lines and clear them from the playfield — a format familiar from the Tetris lineage. The game distinguishes itself with its own block configurations and rule variations. Players use a joystick and buttons to rotate and drop pieces, aiming to manage the rising stack before it reaches the top of the screen. As play progresses, pieces fall faster, increasing the challenge. IQ-Block supports multiple players and includes a competitive mode where clearing lines can send garbage blocks to opponents, adding a direct head-to-head element to the otherwise solo puzzle format.
