What is Kingdom of Numeria?

Kingdom of Numeria is a number adventure game on Roblox. You play a Number Knight, a young hero in a storybook world where numbers are magic. You travel with an old knight named Sir One, solve number puzzles, and restore the crystals of the Great Equation, a circle of ten glowing crystals numbered 1 to 10. At the end of the road is the Null King, who wants to break the patterns that hold the kingdom together.

How the number magic works

Every Number Knight picks a number from 1 to 10 and wears it as a crest. Enemies are protected by wards. To break a ward, you cast spells that add, subtract, or halve numbers. When you play in a party, you combine your spells, so one player's spell sets things up and another player's finishes the job.

That means counting, adding, and taking away are part of how you win, not a quiz you answer between fights. If you are looking for a number game on Roblox where the math is the magic system, that is what this is.

The story: six chapters

The first three chapters follow the Kingdom of Numeria storybook adventures. Chapters four to six are new stories made for the game. After the final chapter, you can go back and hunt twelve bosses for stars, trophies, and new skills.

  1. The Missing Three

    Countingbrook and the Void Hound. The village bell rings twice instead of three times, a lamb has gone missing, and a shield has lost a corner. Follow the trail through the Forest of Figures, past a camp of arguing Plus Goblins, to a Void Hound carrying a black crystal.

  2. The Forest That Forgot to Count

    The Numberwood and the Hushling. A small shadow creature is scrambling the number stones so nobody can follow the paths. Put them back in counting order, and then meet the one who is quietly pleased about the mess.

  3. Numeria Out of Balance

    The Scale-Sand Desert and the Jackal Judge. The Equal Sign has been stolen, and the traders' scales no longer tell the truth. Lady Tenna joins Sir One to follow the trail to a Jackal Judge who declares wrong things as if they were true.

  4. The Valley That Could Not Grow

    Gatherwood Vale, Plus, and the Hoardheart. A collecting golem with a golden Plus crystal for a heart is holding on to everything in the valley. Nib-Nab turns out to be a more useful ally than anyone expected.

  5. The Things We Leave Behind

    The Fading Quarter, Minus, and the Royal Eraser. Things are fading from the city. The Royal Eraser, one of the Null King's lieutenants, believes that erasing something is the same as fixing it, and an old knight named Sir Octavius believes the opposite.

  6. A Place for Nothing

    The Crown of Silence, Zero, and the Null King. The final story. Zero turns out to be a useful number, not an enemy, and the Null King waits for you at the Crown of Silence.

Playing with friends

You can play solo or form a party of up to four players. Each party gets its own private adventure, so you only play with the people you invited. Pick a chapter and a difficulty, invite your friends, ready up together, and depart. Rewards at the end are shared with everyone in the party.

The cast

Who you will run into.

The heroes, helpers, and troublemakers of Numeria.

Sir One from Kingdom of Numeria

Sir One

An elderly Number Knight with a white beard, a pearl-white shield, and a golden 1 on his chest. Kind, brave, and a little dramatic, he always asks before he tells. His knees get suddenly very old whenever something dangerous needs doing.

Lady Tenna from Kingdom of Numeria

Lady Tenna

An old Number Knight who once helped guard the Great Equation. Calm, serious, and kind, she speaks slowly, as if measuring every word. Her staff is marked with a faded 10.

Nib-Nab from Kingdom of Numeria

Nib-Nab

A Plus Goblin: greedy, nervous, and easily impressed. He shouts “Mine!” at everything shiny and tests every Number Knight with the same question: “How many shinies?”

The Hushling from Kingdom of Numeria

The Hushling

A small shadow creature that hides between numbers and loves to scramble them. Dramatic, sneaky, and silly rather than scary. It is thrown off by kindness.

The Jackal Judge from Kingdom of Numeria

The Jackal Judge

A tall, jackal-shaped guardian who hates balance. Calm, proud, and certain it is always right, it declares wrong things as if they were true. “Small is bigger!”

The Void Hound from Kingdom of Numeria

The Void Hound

A shadowy scout that steals pieces of Numeria and carries them off in a black crystal. It growls without sound, its footprints fade behind it, and it sometimes seems to have too many legs, or not enough.

The Null King from Kingdom of Numeria

The Null King

A tall, slender shadow with pale eyes and a thin floating black crown. Quiet and mocking, he says numbers are only rules, and calls breaking every pattern freedom. He is not right.

From the storybooks to the game

Kingdom of Numeria started as a series of story-first tabletop adventures for ages 3 to 7, where counting and comparing are what move the story forward. The first three chapters of the game follow those books:
