Play Wizardry - The Knight of Diamonds Online

Wizardry: The Knight of Diamonds came out on the Nintendo Entertainment System in 1987, developed by Sir-Tech. It was part of that early wave of dungeon crawlers that really pushed the NES beyond simple platformers and action games, offering a deeper, more methodical kind of challenge.

You control a party of up to six adventurers, delving into a massive, multi-level dungeon. The main goal is to retrieve the legendary diamond and escape, navigating the labyrinth one first-person, grid-based screen at a time. Combat is turn-based, requiring you to carefully choose attacks and spells for each character, and the difficulty is punishing; a single wrong turn can lead to a total party wipe, forcing you to reload a previous save. The whole experience feels like a tense, calculated risk with every step forward.
