The lines cannot branch off or cross over each other, and the numbers have to fall at the end of each line (i.e., not in the middle). It is considered that a problem is well-designed only if it has a unique solution [1] and all the cells in the grid are filled, although some Numberlink designers do not stipulate this.
Paint by pairs or Link-a-Pix consists of a grid, with numbers filling some squares; pairs of numbers must be located correctly and connected with a line filling a total of squares equal to that number. There is only one unique way to link all the squares in a properly-constructed puzzle. When completed, the squares that have lines are filled ...
The number of 1 × 1 squares in the grid is n 2. The number of 2 × 2 squares in the grid is (n − 1) 2. These can be counted by counting all of the possible upper-left corners of 2 × 2 squares. The number of k × k squares (1 ≤ k ≤ n) in the grid is (n − k + 1) 2. These can be counted by counting all of the possible upper-left corners ...

Under this view, we write down the example, Grid 1, for =. Each Sudoku region looks the same on the second component (namely like the subgroup Z 3 {\displaystyle \mathbb {Z} _{3}} ), because these are added regardless of the first one.
The "nine dots" puzzle. The puzzle asks to link all nine dots using four straight lines or fewer, without lifting the pen. The nine dots puzzle is a mathematical puzzle whose task is to connect nine squarely arranged points with a pen by four (or fewer) straight lines without lifting the pen or retracing any lines.

Ulam spiral of size 201×201. Black dots represent prime numbers. Diagonal, vertical, and horizontal lines with a high density of prime numbers are clearly visible. For comparison, a spiral with random odd numbers colored black (at the same density of primes in a 200x200 spiral).
