Numeriqo
Calcudoku, taught properly
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Every puzzle is solvable by reasoning alone. When you get stuck, Numeriqo names the technique and draws the argument on the grid instead of filling in the answer.
Numeriqo is a Calcudoku puzzle: fill the grid so no row or column repeats a digit, and every outlined cage hits its target using the operator in its corner.
Most number puzzles leave you to work out the technique yourself, or hand you the answer when you are stuck. Numeriqo does neither.
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 YOU GET FREE
Grids from 3x3 to 5x5 at all five difficulties, the rules tutorial, the first lessons, best times for every grid and difficulty, and a daily puzzle that is the same board for everyone.
ONE PURCHASE UNLOCKS THE REST
Grids up to 9x9, the full technique curriculum, practice drills for each technique, hints that teach, and your full progress. One purchase, no subscription, no adverts, and nothing is collected about you.
Inspired by the Japanese arithmetic puzzles popularised by Tetsuya Miyamoto.
Ratings & Reviews
Numeriqo 3.0 is a rebuild around teaching you the game.
Sixteen techniques with a lesson and a practice drill each. Hints that name the technique and draw the reasoning on the grid rather than filling in the cell. A daily puzzle. Grids up to 9x9. A new board that draws cages as ink instead of tinting them, so colour is left to mean something.
Your best times from earlier versions carry over.
