Sudoku Sova 1.1 — four new kinds of grid, daily leaderboards, and a coach that meets you where you're stuck. • NEW: Killer Sudoku. Cages and sums, four levels graded by technique, and Sova coaches the cage arithmetic and the rule of 45 step by step. • NEW: X-Sudoku, Windoku and Jigsaw. Three more ways to read a grid, each with four levels graded by technique — and Sova coaches every one of them. • NEW: your first board is now walked through, one real deduction at a time. • NEW: Extreme, a level above Master — two-string kites, finned X-Wings, the unique rectangle, BUG+1 and XY-chains, each one taught, drawn and practisable like every technique before it. • NEW: iCloud backup. Your statistics, streaks and night sky are kept in your own iCloud, so a new phone opens where you left off. • NEW: a daily variant too — X-Sudoku, Windoku and Jigsaw take turns, with their own daily leaderboards. • NEW: the year's events. Eight stretches of the calendar, each earning a keepsake for your night sky. • NEW: statistics by week, month or year. • NEW: Daily leaderboards on Game Center, one per level, fair by design: the daily only, on its own day, without hints. • NEW: an optional daily puzzle reminder, at a time you choose. • Drag across cells in Notes to pencil a number into all of them at once. • The selected number now lights up inside your pencil marks too. • The screen stays on while you think. • Stuck on a technique? "Try one like it" opens a short drill and brings you straight back to your game. • Keep a game at every level and each day's daily — undo history included, even after closing the app. • Play any past Daily Challenge from the calendar, share puzzles as codes, save the ones you enjoyed, and colour cells to follow chains. • A new "This week" card, fairer best times, every technique practisable, and many small fixes.
