The Legend of Number Chain
Deep in the Math Maze, where numbers form the walls and equations are the doors, Number Chain was discovered by a mathematician who noticed that all knowledge follows patterns. A sequence with a missing link is like a bridge with a broken plank — it collapses unless the gap is filled.
Number Chain questions present a sequence of values with deliberate blanks — gaps in the pattern that only a sharp mind can fill. The pattern might be arithmetic, geometric, fibonacci-like, or something entirely unique. Your job is to feel the rhythm of the numbers and supply what's missing.
In dungeon lore, the Number Chain boss is said to be an ancient abacus animated by a curse — one that can only be broken by correctly completing its own sequence.
