Sanctum is a competitive strategy board game for 2-4 players, inspired by hack-and-slash RPG video games. Players control unique characters on a journey into the fallen city of Sanctum, building skills and arsenals to prepare for a final fight against the Demon Lord. Gameplay is brisk with overlapping turns. Characters have unique skill sets, allowing for frequent new skill choices as players level up. The game is competitive, with the primary goal being to destroy the Demon Lord, not each other. Player interaction focuses on racing for progress, equipment drafts, reaching the Demon Lord first, and claiming bonuses. The final battle with the Demon Lord is challenging, and surviving is rewarding. The player with the most health after the boss fight claims the glory of its defeat. The game features a dice-throwing mechanism that becomes tactical when combined with equipping the correct gear for survival. The color of the game is described as Mixed Colours.
