Store description excerpt
Four logic puzzles on one square grid. Futoshiki, Skyscrapers, Magic Square and Calcudoku share the same board and the same rule: every digit once per row and column. What differs is the clue around the grid - the signs between two cells, the numbers along the edge, the sum of a line, the target of a cage. Every puzzle is generated when you start it. You choose the size and the level, and for Calcudoku also which operations appear and how large a cage may grow. The hint never leaves you stuck. It names the rule that applies right now and shows the cells it applies to. Every puzzle the app builds can be solved with the techniques of its own level - no guessing, no dead ends. A daily puzzle, one puzzle type per weekday. Statistics, achievements, ten colour worlds, and a newspaper world of its own on iPad. No account, no ads, no tracking. What you play stays on your device. I build this on my own: every rule, every hint, all 45 languages, one desk. No studio behind me, no ads, no tracking, no subscription. Write to me and a person answers. Happy puzzling, Tobias
