The exciting and at the same time relaxing logic training for a player aged 5 and over. At the beginning, 4x4 Sudokus are solved, gradually the increasingly tricky 6x6 Sudokus. The front of the puzzle card indicates the starting positions and on the back the solution can be checked later. With colourful chips that show funny animals or numbers, the fields on the game plan are occupied. No colour should be repeated in a row, column or square. Mind is required here and the learning curve rises steeply upwards. A brain sport that challenges and relaxes at the same time. Thinking sport for clever kids: Does this field belong to the clever fox or rather the cheeky cockatoo? When solving a 4x4 or 6x6 Sudokus, head is required. 30 puzzle cards indicate which chips the fields of the game plan are initially occupied. Then it is good to think over and combine: no colour should repeat in each row, column and marked square. Beginners will first start on the 4x4 plan and gradually get excited for more demanding tasks. With the colour chips, you can choose between funny animals and numbers. It becomes exciting every time after solving the Sudokus on the back of the puzzle card is checked if everything is right. Logic training for a player aged 5 and over strengthens the combination skills enormously and is equally excitement and relaxation
