Jewelriss

■ Developer: BIT Corporation ■ Year: 1991

Obviously, any Game Boy wannabe worth its salt needs a block-sorting puzzle game, and the Gamate has Jewelriss, which is basically just Columns, but with a lot of aesthetic touches stolen from Dr Mario and Tetris. It does have one original touch, though: after you’ve cleared 200 jewels (incorrectly referred to in-game as ‘lines’), the game just abruptly ends. So there’s no possibility of a marathon session. Strange.
