Sudora: Brain Puzzles

Five puzzles in one app: Sudoku, Nonogram, Kakuro, Calcudoku and 2048. Pick one from the lobby — each keeps its own records. Fully offline, no account needed.

Sudora is five number and logic puzzles in one quiet app. Pick one from the lobby and play — each game keeps its own puzzles, its own records, and its own place to pick up from.

SUDOKU Fill the grid so every row, column and 3x3 box holds 1-9 exactly once. Five difficulties, from 45 clues down to 24.

NONOGRAM Also called picture cross or griddlers. Use the number clues along each row and column to work out which cells are filled, and a hidden picture appears. Three sizes: 5x5, 10x10 and 15x15.

KAKURO A crossword where the answers are numbers. Fill each run with digits 1-9 so it adds up to its clue, never repeating a digit within the same run. Three sizes.

CALCUDOKU Each row and column holds every number once, and each outlined cage has to reach its target by adding, subtracting, multiplying or dividing. Three sizes: 4x4, 5x5 and 6x6.

2048 Swipe to slide the tiles. Matching numbers merge and double. Reach 2048 on the 4x4 board, or push for 8192 on the 6x6.
