Solve new Sudoku every day
Sudoku is a great way to pass the time and practice your logic skills. Sudoku puzzles have four basic rules. The same numbers should not occur, firstly, in the same line, secondly, in the same row and, thirdly, in the same 3x3 square. The fourth rule is: the sum of the numbers in each row, line or 3x3 square must be equal to 45. Sudoku is not a puzzle for guessing numbers, here you need to count and analyze the arrangement of numbers. Invite your friends to play Sudoku together or compete against the clock!
