Description: Puzzle game with numbers to be placed onto a grid. The rules of the game are as follows:
1. In the white grid fields, write numbers from 1 to N (N = number of white fields in a row/column).
2. In each row and each column, each number must be written exactly once.
3. The numbers in the black fields are the sums of the numbers in the white neighbor-fields.
The game is a typical logic game: In order to find the correct solution of the puzzle, you have to explore the sums given and numbers already written, and by logical thinking (concluding from what you know, that a given field must be a given number, or on the contrary, can't be a given number), determine, which fields have to contain which numbers.
The game is played with the mouse: Click the field, where you want to write a number, then click one of the number buttons to write the corresponding number or Clear to remove the number from the actually selected field.
Improvement: The generation of 6x6 fields puzzles sometimes takes several seconds. Changing the corr. algorithm would improve game
Free Pascal features: Changing the color of shapes and the caption of static-texts during runtime. Using buttons to insert characters
into a given control's caption. Two-dimensional arrays (classic Pascal).
