Super Iron Board - Gasob's Riddle

Super Xevious: GAMP no Nazo (known in Chinese as 超级铁板阵 - 加索布之谜) is a vertically scrolling shooter developed by TOSE and published by Namco for the Famicom in 1986. Players control the Solvalou spaceship in a mission to destroy the supercomputer GAMP that has taken over Earth. Gameplay involves classic shooter mechanics with power-ups, enemy patterns, and boss fights across multiple stages. The game stands out by incorporating puzzle elements—players must complete unnamed riddle-like conditions in each level (such as flying into specific clouds or clearing certain targets) to unlock the next stage, forcing strategic thinking alongside combat. The story follows the Solvalou crew battling GAMP's forces after an ice age. It features the iconic Solvalou ship design from the Xevious series, with improved difficulty and some enemy additions compared to the original Super Xevious.
