Bag Build Dungeons 2025

Build a powerful dungeon worthy of the Demon King's approval! A strategic tile-placement game using a bag-building system.

Bag Build Dungeons is a simultaneous, bag-building dungeon game where each player acts as a dungeon manager trying to impress the Demon King by constructing the strongest dungeon.

Each round has four phases: (1) draw five monster tiles from your bag, (2) gain bonuses present on the tiles drawn, (3) place one drawn monster onto your personal dungeon grid following adjacency and placement restrictions (or take a penalty if you cannot legally place) and (4) use the remaining drawn tiles to attract stronger monsters by paying specific tile combinations or substituting mana, then return unused tiles to your bag.

Over time your bag improves with stronger monsters, which both score more and fuel future draws. After 16 rounds, players score points from their monsters (in bag and placed), possibly score objective cards, and may lose points for penalties. The highest total points wins, with leftover mana as a tiebreaker.
