NumbersGrid

An Immaculate Grid style puzzle with numbers: each square needs a positive integer that satisfies both its row and column property, such as primality, digit patterns, divisor sums or figurate forms. No number may repeat, and rarer valid answers score more than obvious ones. A practice mode generates random grids.
