Kakuro Paradise Java Game

Another great collection of puzzles with numbers. Check the sharpness of your mind and solve its puzzles!
The game field is made up of cells. Lateral cells are filled with numbers - they are the sums of digits that can be inserted into horizontal or vertical rows. The numbers (from 1 to 9) must not be repeated. For example, if the amount of horizontal row is 6,you can add the numbers 1 and 5 or 2 and 4, but you can not insert 3 and 3 in this series.
It sounds simple, but carries no worse than a crossword puzzle. It is recommended for long journeys and queues. One party in Kakuro last from several minutes to an hour!
