Sudora is now six brain puzzles in one app. NEW: MEMORY GRID Squares light up for a moment — tap them all back from memory.

ALSO NEW • A lobby to pick your puzzle: Sudoku, Nonogram, Kakuro, Calcudoku, 2048 and Memory Grid • Every game keeps its own records and saves your progress • A roomier layout on iPad Your Sudoku best times and any puzzle in progress carry over untouched.

Sudora is now five puzzles instead of one. A new lobby opens the app, with Sudoku joined by Nonogram, Kakuro, Calcudoku and 2048. Tap an icon to play — each game keeps its own records and its own saved puzzle. Your Sudoku best times and any puzzle you had in progress carry over untouched.

TUTORIAL New to sudoku, or just to Sudora? A short interactive tutorial now walks you through the rules, the highlighting, pencil notes, and the mistake counter — on a real grid, at your own pace. Open it from the home screen whenever you like, and skip it entirely if you'd rather just solve. MORE PUZZLES The home screen now includes a small section for our other puzzle apps, in case you want something else to think about once the grid is done.

• Best Times by Difficulty: Sudora now tracks your fastest completion time for each difficulty level, so you can see your personal best at a glance. • New Record Celebration: Beat your best time and enjoy a special celebration the moment you set a new record.
