Languages
The puzzle apps are not translations. Each one was written in its own language from the start, because a crossword clue that has been through a translator stops working as a clue.
Kryds og Træks, Ordhjul and Terninger are Danish, with Danish clue conventions and the full æ, ø and å alphabet. Slovokolo and Enigmatika are written for Serbian, Croatian and Bosnian readers, in proper Cyrillic and Latin orthography rather than transliterated into it. Azbuka runs the other way and teaches the Cyrillic alphabet to English speakers from scratch. Jolt, Sudoku Studio, Bimaru, Acuity and Elixir Lane are English.
Coming
A few more are in testing and not on the store yet. If you want to know when one of them lands, email me and say which.
