Dungeon Master is a role-playing game where the player selects four adventurers and descends into the depths of the dungeon. The gameplay is reminiscent of the 3D dungeon crawl type of role-playing games popularized by Wizardry and The Bard's Tale. However, unlike these games, Dungeon Master features real-time combat, which requires the player to click on the opponent in order to execute an attack.
The game also has a growth system: instead of gathering experience points and leveling up, characters improve by repeatedly using the same action. Spellcasting involves selecting and combining symbols, which can be arranged as rune sequences. The game allows the player to directly interact with objects in the game world through a point-and-click interface.
Players control their party of four adventurers through a series of challenges and puzzles as they navigate the dungeon.
