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. ## Key features - Step-by-step technique introduction - Hint system that explains reasoning - Guaranteed single solution puzzles - No guessing required - Daily puzzles - Progress tracking ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Numeriqo Full | $4.99 | one-time | ## Frequently asked questions about Numeriqo ### What is Numeriqo?

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. ### 2.0 — 2026-07-25 A complete visual redesign. Numeriqo 2.0 now matches its icon: soft blue surfaces, a glowing wordmark, and embossed math symbols floating behind the home screen. Cages are drawn as rounded tiles with crisp blue outlines, so the board is easier to read at a glance. The number pad, size cards, and buttons have all been rebuilt in the new style. Both appearances got equal attention: a pale ice-blue look in light mode and a deep navy look with glowing accents in dark mode. Layouts are also refined on iPad, Mac, and Apple Vision Pro. Same puzzles, same rules, same best times — everything you solved still counts. ### 1.2 — 2026-07-11 Fairer puzzles! Every puzzle is now guaranteed to have exactly one solution. Choose your challenge with new Easy, Medium, and Hard difficulty levels for every grid size. Smarter move validation, and best times are now tracked per difficulty. ### 1.1 — 2026-02-20 Full dark mode support. The game now automatically adapts to your system appearance with improved contrast and readability in both light and dark modes. All grid elements, cages, and controls update seamlessly when you switch between appearances. ### 1.0 — 2025-09-16 No release notes. ## More apps by Kai Kunze - [Blanks](https://appshunter.io/ios/app/blanks/id286883373) - [MoreBlanks](https://appshunter.io/ios/app/moreblanks/id288808376) - [Gait](https://appshunter.io/ios/app/gait/id765009072) - [Gait Pro](https://appshunter.io/ios/app/gait-pro/id6502754730) - [ai-Memo](https://appshunter.io/ios/app/ai-memo/id6502860819) - [ai-Memo Pro](https://appshunter.io/ios/app/ai-memo-pro/id6503480155) All apps by Kai Kunze: https://appshunter.io/developer/286544358 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
