Little Monster Detectives, First Edition - Rules SummaryCollapse

Character Creation [ edit ]

Contracts, Not Character Sheets

Little Monster Hunters doesn't have "characters" per say, although it does have a sort of "character sheet" known as a detective contract.  Unlike most RPGs, a new contract is created before every game.

Different Contracts for Different Player Types

There are three versions of the contract total: two for "beginner detectives", ie. players, and one for "senior detectives", ie. game masters (there are two player contracts because one is simplified for younger children.)

The simplified version has a place to store the player's "stuff" (items) and stars, while the full version also has a place to store clues found.  Both also let the player specify a new (made-up) name for their character, which is really the only "character creation" involved.

The senior detective contract doesn't have stars, but does have a "stuff" section, and also has an expanded clues section (since they created the adventure/clues), plus a short rules summary to help run the game.


Little monster detectives don't advance in any traditional way (ie. with levels).  However, players are rewarded with badges (stickers) for bravery, teamwork, etc., and can also acquire tools from the detective agency.

Core Mechanics [ edit ]

To accomplish tasks in Little Monster Detectives, the players roll three dice and picks one based on the circumstances.  If the task is easy they need only roll a 2, but if it's normal they need a 4, and for a difficult task they need a 6. A roll of a 1 is considered an "epic failure", while a roll of a 6 is considered an automatic success.

Which of the three dice is kept uses a system similar to advantage/disadvantage in other RPGs (like Dungeons and Dragons).  If the player has recently been bitten by or is currently scared of a monster, they pick the lowest die rolled.  If they have an appropriate tool for the job, they instead get to pick the highest die rolled.  Finally, if neither applies, they take the middle die.

There are no further mechanics, but the senior detective is encouraged to adjust difficulties as needed.  For instance, there are no explicit team work rules, but the book suggests that having two players team up might lower a difficulty from six to four.

Combat [ edit ]

Little Monster Detectives is purely an investigative game, and as such has no real combat rules.  However, players can get "bitten" or "scared" by monsters.  Players become scared when the team fails to find enough clues: this causes the fear rate to increase, which then makes the players roll dice to avoid becoming scared.

Even when the players finally find the monster at the end of the adventure, there still is no combat: they simply collect it and add its token to a glass jar, which they can later turn in to the monster detective agency (so the monsters can be rehabilitated).
