Enigma

Released in 1996 for DOS, Enigma is what happens when a puzzle game decides it’s not content with simply challenging you—it wants to tease you, mock you, and eventually charm you into staying. It blends logic puzzles with an atmospheric style that feels slightly ahead of its time, even if the hardware wasn’t. The game rarely holds your hand; in fact, it seems proud of dropping you into situations that make you doubt your intelligence. But when you finally crack one of its tougher riddles, you’ll swear you hear the game whisper, “Took you long enough.”
