Square One
Official Description:
Square One is an engine-building strategy game that builds upon the foundation of its predecessor, Project L. The game features easy-to-learn yet challenging mechanics, offering high replayability for players. In Square One, players use colorful squares to complete sequences at the right moment, gaining new tiles and maximizing victory points. The gameplay revolves around sequencing pieces onto tiles for optimal payouts. Players must carefully plan their actions, as learning how to play is straightforward with a set of clear actions laid out on a helpful player aid. The dual-layered boards and slotting tiles add a tactile and strategic element to the experience. Square One is designed for 1-4 players and emphasizes both accessibility and depth. Its streamlined rules and engaging engine-building mechanics make it suitable for a wide range of players, from newcomers to experienced board gamers, ensuring each session is both strategic and rewarding.
Square One is currently in the early stages of collection integration—a recent arrival that’s getting its first real table time. The main tactical appeal for seasoned players is the shift from polyominoes to a uniform square tile system, which demands a different kind of spatial logic. This abstracted approach to engine-building feels like a deliberate evolution, not just a re-skin, and it’s the kind of mechanical twist that prompts veterans to re-examine familiar strategies. The game’s standalone nature and puzzle-forward design make it a compelling test case for groups who already know Project L but want a fresh challenge. Physically, Square One is built for collectors: the box is sturdy, the custom trays keep the square tiles sorted, and setup is straightforward—about 15 minutes from shelf to play. The uniformity of the tiles streamlines both storage and table management, but you’ll still want a decent play surface to keep everything organized. With a 50-minute session time, it’s best positioned as a main event for a focused group, not a filler or warm-up. The tactile slotting of tiles into dual-layered boards adds a satisfying physicality, but it’s not the kind of game you can squeeze in between heavier titles without some prep. From a teaching standpoint, the rules are accessible, but the spatial logic is a step up from the original. New players will grasp the basics quickly, but optimal play requires a few rounds to internalize the sequencing and timing. Once the first round is underway, you can step back—parallel play means players are mostly heads-down, working their own puzzles, so the room stays focused but low-key. There’s little direct interaction, which keeps the energy steady and lets you manage other tables if needed. For groups who enjoy engine-building with a cerebral twist, Square One delivers a familiar satisfaction in a more abstract, puzzle-driven package.
