Sumoku - Seven-segment Math in IOS

Make 10 with digital numbers

Walkthrough, Guilds, Tips on this special game

Our Expert Score

80/100

Sumoku is a brilliant fusion of Sudoku and crossword-style layout, but with a math-focused twist. It’s the kind of game that is easy to learn but difficult to master. The core mechanic is simple: place tiles so that the sum of each row and column is a multiple of a given key number. It requires a different kind of 'brain-wiring' than typical number puzzles, focusing on mental arithmetic and spatial planning.

The app is clean and distraction-free, which is perfect for a logic game. The 'seven-segment' math aesthetic is cool and retro, making it feel like playing on a classic calculator. It’s a great educational tool that actually feels like a game, making it perfect for kids practicing multiplication or adults who want to keep their mental math sharp. It’s a quiet, clever, and highly replayable puzzle game.

Available on: iPhone, iPad, iPod

Version 2.0.1Thu Oct 21 2021

• Optimized for iOS 15

• Minor improvements


Sumoku is a game of digital numbers.

Your goal is simple: create combinations of numbers equaling 10 by sliding them around the grid.

Move digits horizontally or vertically “flipping” them into place.

Since the numbers are digital, reversing them can change their value. For instance, a 2 can be flipped into a 5 or a 6 into a 9.

Be careful to create a non-number in the process since the number cannot be used until it is set right.

There are also “special” green and red digits that cannot be flipped but provide you powerful bonuses.

You can choose from three modes:

Classic - eliminate a set amount of numbers as quickly as possible;

Puzzle - get rid of prearranged groups of numbers in as few moves as possible;

Endless - do the best score before the grid is full.

Sumoku supports iCloud and Game Center (both Leaderboards and Achievements).

There are two themes available: Light and Dark.
