Numeriqo Pro

Numeriqo Pro is a Calcudoku puzzle, bought once and complete: fill the grid so no row or column repeats a digit, and every outlined cage hits its target using the operator in its corner.

Everything is included. No in-app purchases, no subscription, no adverts, and nothing is collected about you.

TAUGHT, NOT ASSUMED

Sixteen techniques, introduced one at a time, from single-cell cages up to X-Wing. Each lesson is a short explanation followed by a puzzle that needs the technique you just read about. Your progress on each one is tracked, and counts only the solves you managed unaided.

HINTS THAT EXPLAIN

Ask for a hint and Numeriqo tells you the region first. Ask again and it names the technique. Ask again and it draws the reasoning on the grid, cell by cell. Only the last step will place a digit for you, and taking it is a deliberate act rather than the default.

NO GUESSING, EVER

Every puzzle has exactly one solution, and every puzzle is checked before you see it to make sure the techniques in the app are enough to finish it. You will never be asked to guess and backtrack.

WHAT IS INCLUDED

Grids from 3x3 to 9x9 at five difficulties. The full technique curriculum with a lesson and a practice drill for each. Hints that name the technique and draw the reasoning. Best times, solve counts and your mastery of every technique. A daily puzzle that is the same board for everyone.

Inspired by the Japanese arithmetic puzzles popularised by Tetsuya Miyamoto.
