A sudoku that goes somewhere.
Interstellar Sudoku is a sudoku game for iOS and Android. There is no difficulty to choose: every puzzle is a stop on one long journey, and solving it moves you on to the next.
In development. The app is not in the App Store or on Google Play yet.
How it plays
-
One journey, no difficulty menu
The journey hands you the next stop, and its difficulty comes with it, from easy to expert. Each attempt runs under that stop’s time limit and mistake limit. Solve it, and it becomes a star on the path behind you.
-
A daily challenge
One extra puzzle each day, the same one for every player, and gone at midnight.
-
Hints that give the reason
A hint fills a square and names the technique that forces that digit there. Notes, undo and redo are there for working it out yourself.
-
A streak, and shields for it
Solve something every day and a streak builds. Streak shields, earned by playing, cover a day you miss. Solving also earns experience, levels and badges.
The game comes in English, Spanish, Portuguese, French, German and Italian.
Who makes it
Interstellar Sudoku is made by LigockiTech, a technology, software and data consultancy in Florianópolis, Brazil. It is the first app we will publish ourselves.
