A game to practice logic and combinatorics. At the beginning of the game, the first player secretly places any combination of four colored pegs in a hidden area under the game board. The second player tries to guess this combination by creating a combination of four pegs in turn in individual rows on the game board. The first player evaluates each of his attempts using small evaluation pegs as follows: for each peg that the guessing player placed in the correct color in the correct place, he assigns a black peg, for each peg that the guessing player placed in the correct color but in the wrong place, he assigns a white peg. The guessing player does not know for which peg the evaluation pegs were assigned. The game ends when the guessing player guesses the combination (the winning attempt is therefore evaluated with the full number of black pegs). The players then switch roles and the game continues. The winner is the player who needed fewer attempts to guess. Age: 3+. Dimensions: 30.5 x 16.5 x 2.5 cm.
