Real Kakuro

Real Kakuro is an adaptation of the puzzle Kakuro, which is similar to a crossword, but with numbers. Each number is marked with a clue which tells the sum of all digits within the number. No digit may be used twice within one number.

The game contains 2000 puzzles divided into 5 difficulty levels. While solving, it is possible to use a "pencil" tool to note down the possible number that can be in a given square. A "Cheat Sheet" option makes solving easier: when pointing to a specific square, the player is informed about all the possible combinations of digits that can make up the required sum, taking into account numbers already filled in.

The game is ad-supported, and allows disabling ads via an in-app purchase.
