About the game

Thirteen grid and word puzzles, solo: sudoku, killer sudoku, kakuro, calcudoku, futoshiki, binairo, str8ts, nonogram, Guess the Word, word search, crossword, arrow words and fill-ins.

The sudoku draws a fresh grid every game, its solution proved unique while it is carved — never a pre-generated batch, never the same twice. Guess the Word gives six tries to find a five-letter word, in all five languages of the app.

Seven of the thirteen puzzles are played without paying anything; the free version asks for a connection and shows an advert between games. A single purchase — no subscription, no currency — opens the other six, removes every advert and all tracking, and makes the app usable with no connection. No account, either way.
