Released for the Game Boy Advance, "2 Games in 1 - Columns Crown + ChuChu Rocket!" is a SEGA-published compilation cartridge that bundles two of the company's beloved puzzle titles into a single GBA package. The compilation format was a common strategy during the GBA's lifespan, allowing publishers to offer added value on a single cartridge and introduce players to titles they might have missed on earlier platforms. Both games in this package have roots in SEGA's arcade and Dreamcast history, making the compilation a convenient portable home for two distinct puzzle experiences.
Columns Crown is a streamlined entry in SEGA's long-running Columns series — a gem-matching franchise that predates many of its contemporaries in the falling-block puzzle genre. In Columns Crown, colored jewels fall in vertical stacks of three, and the player must rotate the order of gems within each falling stack before it lands. Matching three or more gems of the same color in a horizontal, vertical, or diagonal line causes them to disappear. The game introduces a "Flash Gem" mechanic: a special sparkling jewel that, when matched, clears every gem on the board sharing that color, enabling dramatic chain reactions and board-clearing combos. The GBA version retains tight, responsive controls well-suited to the handheld's button layout, and the game offers both a standard endless mode and a head-to-head challenge mode for two players via a link cable.
ChuChu Rocket! is a fast-paced, real-time puzzle game in which players place directional arrows on a grid to guide mice (ChuChus) into rockets while steering them away from cats (KapuKapus). Originally released in arcades and on the Dreamcast — where it was notable as one of the first online multiplayer console games — the GBA port distills the core experience into a handheld-friendly format. The game features a large library of puzzle stages that test spatial reasoning and planning, as well as a frantic multiplayer mode in which up to four players (with additional cartridges) compete to funnel the most ChuChus into their own rockets. The single-player puzzle mode alone offers dozens of hand-crafted stages of escalating complexity, providing substantial content for solo players.
Together, the two games represent a strong cross-section of SEGA's puzzle output from the late 1990s and early 2000s. The compilation format means players get meaningful variety: Columns Crown delivers a meditative, score-chasing experience, while ChuChu Rocket! offers kinetic, time-pressured chaos. Both games are well-optimized for the GBA hardware, with clean sprite work and responsive input. The link cable multiplayer support for both titles adds longevity, though the two-player requirement for competitive play is a limitation in practice. For puzzle fans who owned a GBA, this cartridge represented an efficient way to enjoy two quality SEGA puzzle games on the go.
