Players of Resident Evil Requiem faced challenges with The Final Puzzle, which involved deciphering a series of numbers linked to celestial symbols. The gaming community solved the puzzle in four days through datamining, surprising even the developers at Capcom. Producer Masato Kumazawa initially doubted the puzzle's solvability. A complex segment included a conveyor belt and grinder sequence requiring a 15-minute wait while avoiding zombies. Players theorized that the goal was to flood the grinder system to bring a doll to the surface. Afterward, players had to return to a hospital bathroom to flush a toilet eight times, linked to a clue involving a dead body with the number eight written in blood. This task was part of the process to flood the system, retrieve the doll, and complete the symbol puzzle for in-game currency rewards.
