Palamedes is a game where your goal is to clear the screen, line by line, filling up with dice. You control a small person near the bottom of the screen who can only move left or right. The B button changes the number on the dice you're holding, and pressing A shoots it upwards.
pressing down after lining up at least three dice in the same row or consecutive numbers will destroy up to five lines at once.
The game has three modes of play: a single-player mode where you must destroy a set number of lines to progress, a tournament mode against CPU-controlled opponents, and a two-player mode.
