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.
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.
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.
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.
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.
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.
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.
