What Build a Dungeon Is on Roblox
[GUILDS] Build a Dungeon is a Roblox experience developed by Exploration Guild. The official game page describes the premise directly: build your own dungeon, defeat endless waves of heroes, put monsters in the dungeon to loot heroes, and collect cool buildings and strong monsters for more cash. The same page states that the game is in beta and updates regularly.

The bracketed word in the title is an update tag rather than a different game: tracking sites recorded the same place moving from [LABYRINTH] Build a Dungeon to [GUILDS] Build a Dungeon. Games with similar names on other platforms are separate titles, and their systems do not apply to this Roblox release.
How a Run Works
Heroes spawn at a one-way entrance and walk the route you build, so the corridors, turns, dead ends, and rooms you place decide how long they take to reach the dungeon crystal you are protecting. Recorded gameplay shows heroes following the laid path, turning back at dead ends, and walking the full route before they reach the crystal.
Roll for building pieces: corridors, floors, walls, and rooms come from rolls paid for with Coins; connect the entrance to the crystal and use turns, loops, and dead ends to keep heroes walking through your defenses.
Place monster units: units are obtained with Dark Souls and stand along the route to fight the wave.
Add traps: trap tiles bought with Coins slow or damage the heroes passing over them.
Fight the wave: you can fight beside your units or leave the battle on auto battle, then reinvest the rewards.
Recover from a loss: when a wave breaks through, the run restarts from your last checkpoint. Recorded gameplay shows a checkpoint at wave 10, and the Update 6 notes added a dropdown for returning to an earlier checkpoint.
Coins, Dark Souls, and Booster Potions
The game uses two currencies. Coins are exchanged for buildings and defensive traps, while Dark Souls are spent on monster units. Both are earned by defeating waves of heroes, and both also arrive through redemption codes.

Quests and a spin wheel also feed the reward loop, and the Update 6 notes mention improvements to the spin wheel. The official page confirms that monsters catch heroes offline, so the dungeon keeps earning while you are away, and the escape menu reports an estimated hourly rate of Coins and Dark Souls based on your highest wave.
Monster Units, Rarities, and Mutations
Monster units defend the dungeon. Some fight up close, some attack from a distance, and others heal or buff nearby units. Units are obtained by rolling with Dark Souls, and recorded gameplay places the roll milestones at a Legendary by 80 rolls, a Mythic by 160, a Secret by 300, and a Divine by 2,000. Official drop rates and pity thresholds are not published, so the in-game interface is the authority for current numbers.

Mutations do not change a unit's attack interval, range, or ability percentages, and units can be upgraded separately, with the game tracking their power value. Boss units receive 50% more health and damage while standing in a Boss Room.
Buildings, Rooms, and Traps
Pieces seen in recorded gameplay include stone corridors, wooden floors, curved walls, curved corridors, dead ends, crossroads, junctions, armories, treasure rooms, dragon nests, graveyards, lava chambers, frost stone walls, wooden barricades, ballista towers, turrets, blacksmiths, Life Springs, and the Shrine Tiles added in Update 6.
Traps seen in recorded gameplay include spike traps, poison traps, tar pits, bear traps, arrow traps, fire traps, falling rocks, oil, and lava floors. The interactions confirmed in that gameplay are specific:
A tar pit only slows heroes down.
Oil leaves heroes burning for three tiles after they step on it, and the fire keeps being reapplied across those tiles, while a lava floor increases the fire damage heroes take.
An arrow trap is placed on a corridor or wall position rather than in open space.
Mechanics That Change Your Layout
Potion shops: heroes stop to buy potions on their way through, and recorded gameplay treats potion shops as one of the main sources of Coin income.
Treasure rooms: heroes are guaranteed to head for a treasure room, which turns it into a deliberate detour away from your crystal.
Thief heroes: disarm traps within a one-tile radius around themselves.
Healer heroes: support the invading wave, and recorded gameplay treats them as a problem for damage-over-time trap builds.
Archer heroes: can attack through walls, while your own units cannot attack through a wall at all.
Skill tree: percentage upgrades include gold rush, soul harvest, unit damage, population, trap mastery, battlecry, and battle speed; Update 6 unlocked the 2x Battle Speed upgrade earlier in the tree.
Auto-roll filtering: added in Update 6 to manage repeated unit rolls.
Updates, Labyrinth, and Guilds
Update 6, per the developer announcement, added a randomly generated Labyrinth with three floors of monsters and treasure chests that can be explored solo or with friends, with rewards shared in a group and scaled by difficulty. The same update introduced five new units and tiles, four Labyrinth-exclusive units, and four Shrine Tiles that buff units placed around them, with nothing allowed on top of a Shrine Tile. It also added Divine pity and Mutation pity, advanced auto-roll filtering, the earlier 2x Battle Speed upgrade, strengthened hero waves above 500, a dropdown for returning to a previous checkpoint, and fixes for saves, the index reset, and the spin wheel.
Update 7 is summarized by the community reference as "Guilds are now in beta", pointing to update notes that cover mutation changes, trap upgrades, and auto rejoin. That summary is a lead, so confirm the details in the official Discord or in the game itself.

Tip
Because heroes are guaranteed to walk toward a treasure room, a treasure room placed away from your crystal works as a deliberate detour while your units and traps handle the heroes who take the direct route.
Coins buy buildings and defensive traps, while Dark Souls obtain monster units. Coin Booster and Soul Booster Potions temporarily raise your earnings.
Do monsters keep working while I am offline?
Yes. The official page states that monsters catch heroes offline.
How do I get Legendary, Mythic, Secret, or Divine units?
Keep rolling with Dark Souls. Recorded gameplay places the milestones around 80 rolls for a Legendary, 160 for a Mythic, 300 for a Secret, and 2,000 for a Divine, while official rates and pity thresholds remain unpublished.
Why do some heroes ignore my traps?
Thief heroes disarm traps within a one-tile radius, and archer heroes attack through walls while your units cannot, so a trap-only layout can be disarmed or outranged.
Is this the same game as other dungeon titles with similar names?
No. This page covers the Roblox game by Exploration Guild, and similarly named games on other platforms are separate titles with their own systems.
