You Must Build A Boat is a 2015 puzzle-RPG hybrid developed by EightyEightGames, available on Windows, Mac, Linux, iOS, and Android. A sequel to 10000000, the game centers on a dual-focus mechanic in which players simultaneously manage a 6×8 sliding tile grid and navigate a side-scrolling dungeon run. Matching rows or columns of three or more tiles triggers attacks, unlocks chests, disarms traps, or grants resources in real time as a character sprints through procedurally generated dungeons. Progress is directed toward expanding a boat by recruiting crew members — including undead navigators and monster allies — and completing quests that can be stacked to voluntarily increase difficulty. Between runs, players trade collected items and resources to upgrade equipment such as weapons and magic staves. The game employs a retro visual aesthetic and is structured around incremental goal-setting, encouraging repeated attempts and steady accumulation of improvements over many sessions.
