''ChuChu Rocket!'' is an [[Puzzle video game#Action puzzle|action puzzle game]].<ref name="Gspyrev" /> The basic rules of the game require the player to guide mice, dubbed "ChuChus", into a rocket while evading them from dangerous cats, dubbed "KapuKapus".<ref name="manual" />{{rp|8–9}} A brief premise is provided in the instruction manual, explaining that ChuChus are living on a space port that is invaded by KapuKapus one day. In their frantic state, the ChuChus begin running around in chaos, and so the player must guide them to their rockets to save them.<ref name="manual" />{{rp|2–5}} Both ChuChus and KapuKapus run in a straight line, and turn right when they hit walls. A player can place up, down, left, and right arrows on the field of play, redirecting characters that step on them. Up to three arrows can be placed by a player at any time; placing a fourth arrow will make the player's oldest arrow vanish, and all arrows fade away over time. If a KapuKapu hits an arrow twice, the arrow disappears.<ref name="manual" />{{rp|6–9}}

There are several modes of play within ''ChuChu Rocket!'' including a single-player puzzle mode, a puzzle editing mode, a cooperative challenge mode, and competitive multiplayer modes. In the puzzle mode, the player is provided a limited set of arrows to place on the field to save all the ChuChus in play. The puzzle editing mode allows players to create their own puzzles like this. In the challenge mode, players are given 30 seconds to save the ChuChus in play without any arrow limitations as in puzzle mode. In the competition modes, each player has a rocket and must guide as many ChuChus as possible into their rocket in the time limit. This mode supports up to four players, either in free-for-all or team-based fashion.<ref name="manual" />{{rp|10–17}}
