IQ-Block (V100U)

IQ-Block is a two-player puzzle game released in 1993 by IGS. Players use an eight-way joystick to manipulate falling blocks and strategically place them within a shared playfield. The objective is to clear lines by filling them completely, similar to other drop-style puzzle games, while competing against your partner for the highest score. A Zilog Z80 processor powers the gameplay, accompanied by sound from a YM2413 chip. The game’s demo mode notably contains an amusing typographical error in the displayed text, misspelling “insert coin.” IQ-Block offers straightforward controls with four buttons and encourages quick thinking and spatial reasoning as players react to increasingly rapid block drops. It's a cooperative yet competitive experience designed for two players seeking a focused puzzle challenge.
