The IQ FUN pack contains fun Sudoku and Calcudoku puzzles and is specially designed for children aged 7–9. The aim of Sudoku is to fill the grid with numbers from 1 to n (where n is the number of rows in the grid) so that no number is repeated in any row, column, or sub-grid.

In Calcudoku, the grid is divided into regions that must be filled with numbers from 1 to n. Using the indicated operation, the numbers in each region must produce the result shown in its corner, without repeating in any row, column, or region.

Sudoku and Calcudoku puzzles develop logical thinking, improve associative memory and calculation speed, boost concentration and attention, and train reasoning, sharpness, intelligence, and fine motor skills. For best results, children should practise for at least 15 minutes a day.

The brain games in these educational cards are more than just worksheets: they stimulate creativity, encourage logical thinking, test problem-solving skills, improve attention, and train memory. All these brain processes are equally important. By practising them, children can discover their potential and develop the cognitive skills they need to succeed in everyday life.
