Play this game based on the theme of the ever-popular numbers game and your number could be up! You could win big if the numbers 1 to 9 appear in the boxes right.

Sudoku has only 2 pay lines and the equivalent to 9 reels. All the ROWS are one and all the COLUMNS are the other pay line. A row or column can contribute to a win if it contains all the numbers 1 to 9. You need at least 3 rows or 3 columns for the minimum payout. The maximum jackpot is 6000x your coin value and it's paid if you get 9 rows or 9 columns appear containing the numbers 1 to 9.

There's a bonus of 8000 if you get both 9 rows and 9 columns. The STAR symbol is WILD and substitutes for all numbers. If 5 or more of the small Suduko SQUARES are completed, you get 15 FREE GAMES in which all wins are doubled except the SUDOKU FEATURE.

 If 7 or more RED NUMBERS appear, the SUDOKU FEATURE is triggered in which you win 5 RE-SPINS. In each re-spin, the RED NUMBERS are held. There are 27 RED NUMBERS in total. During the re-spins, if all 27 appear you win the TOP BONUS prize of 25x your coin value. During the SUDOKU FEATURE, standard winning combinations are not paid. The highest coin value is £20 and the Autoplay feature allows any number up to 99 automatic games.

Sudoku is mildly entertaining. The maximum payout is 20,000x your coin value and pays out when you get all 9 rows and all 9 columns, which means you complete Sudoku on the whole board.

Unfortunately, the screen content never changes much as the bonus feature uses the same Sudoku board as the main game, so I'll play it for a bit, but likely to go find something more engaging sooner rather than later.
