What it is
The Missing Three is Chapter 1 of the Kingdom of Numeria series. The Number Three is disappearing from the world, and the children are newly chosen Number Knights sent to Countingbrook to find it. The adventure runs on one rhythm: notice what's wrong, solve it, then use the answer to change the scene. A missing count reveals a trail; a shape missing a corner opens a path. It ends with the party facing a Void Hound serving a mysterious, recurring villain called the Null King, who reappears across the series.
Character creation takes about a minute: each child picks a silly knight name, a favorite number, one Brave Thing (Strong, Quick, Clever, Kind, or Magical), and one Helpful Item. No character sheet, no reading required from the kids. The DM reads the story aloud and the children point, count, and decide.
Best for
Parents or caregivers running a first tabletop game with 1 to 4 kids, including a single child playing one-on-one. Works for a child who's ready to count along with a story rather than fill in a worksheet, and needs no prior Game Master experience.
What the Game Master should know
Every “wrong answer” is designed to move the story sideways instead of stopping it: a clue moves, a goblin grabs something, nothing ever becomes a dead end. The included printable challenge sheets double as the visual puzzles for their matching scenes. Plan for 60–90 minutes; younger groups can split the session at a natural break. See Tabletop RPGs for Kids for a plain-language rundown of how a session works before you start.
