The classic game of Sudoku is a number-based puzzle where players are required to follow a simple rule. The digits on each row, column, and 3x3 subgrid must contain all numbers from 1 to 9. As a result, there shouldn’t be repetitions. The Sudoku card starts with some of the positions filled out and you must use logic to enter the other numbers until the entire 9x9 grid is full.

The roots of the game go back to the 19th century in France. One of the leading newspapers in the country published a similar game in 1892 where readers had to solve a partially filled 9x9 square while making sure that each column, row, and mini-square had the same total value. In 1895, another French newspaper presented a refined version of the puzzle game that was more like the modern Sudoku games.

It wasn’t until 1979 that the Sudoku rules were set by a freelance puzzle developer in Indiana. The name was granted by a puzzle company in Japan. Sudoku in Japanese stands for single number. The game went on to reach massive popularity around the world. Nowadays, Sudoku can be found in many newspapers, and there are even small books with different cards to help fans pass the time. Of course, you can also find Sudoku online to play at home and on your mobile device.

The title even reached some online casinos, with a special betting game developed by Rival. While it shares the same name, the actual gameplay is more like a slots machine than the classic Sudoku game that most people are familiar with. However, there are still some similar elements and players stand to win enormous prizes for all 1-9 numbers on the screen.

At first, Sudoku as part of an online casino gaming collection stands out for fans of the classic game. Since the name is the same, it can catch the attention of players who enjoy numeric puzzles. However, the gameplay is not the same, and you don’t have to fill out any numbers on the screen. This is not an issue since players are likely to play a few rounds of casino Sudoku for the name alone. Then, it is easy to enjoy the simple system and continue betting for a while longer.

The game is very similar to slots so if you enjoy the spinning reels you might like Sudoku as well. There is even a Spin button for starting a new round, so it is clear what the developer had in mind when creating this casino game. You can select the size of the bet from the interface, and the range is very welcoming for all. Minimum bets are of €0.01 while the maximum is of €10 per round.

Another reason for its popularity is that the payouts can really go up. The biggest prize is of 50,000 coins; a jackpot which is awarded for getting all the numbers from 1 to 9 in order on the 3x3 grid.

The design is pretty engaging, and there are plenty of chances to claim prizes. There is even an autoplay option that you can use to play round after round without having to press the spin button every time.

The name can be a bit misleading for those that are familiar with the standard puzzle game of Sudoku. In the casino version, you do not need to fill out any boxes to complete the card. Instead, the screen will show nine boxes with random numbers. Payouts are granted for matching numbers on the screen, starting with 1:1 for three matched symbols. If you get the entire 3x3 screen filled with the same number, you will receive a payout of 2,000:1.

Before you can win, however, you need to set the bet size. This can be done by choosing a coin value from the dashboard and then selecting between one and five coins to bet. After you make sure that the wager is the one you want, you can click on the spin button located in the bottom right corner. This will start a new round and will present nine random numbers on the screen. Payouts are granted automatically, and the matching numbers are highlighted.

That is pretty much everything. The game rules in Sudoku are straightforward, and the gameplay is the same as in most classic slots. The only difference is that there are no paylines in this casino game and matching symbols pay in any position as long as they appear in groups of three or more. The addition of two jackpots is a bonus, and they help include another Sudoku element to the theme. Even if the numbers are not in ascending order, you still win 500 coins for getting all digits 1-9. If they are in order, however, you earn 50,000 coins. You need to bet five coins to be eligible for the jackpots.

You can find the casino version of Sudoku at a handful of online casinos under the category of Specialty Games.

The game ratings for Sudoku present an option that is very simple. It doesn’t require skill to play, and it is not difficult to learn, at all. The only thing that you need to do is set the size of the bet. After that, you can spin or use the auto play function to let the game play by itself, round after round. It is similar to online slots, a type of game that is hugely popular at online casinos and so Sudoku might actually have a chance.

On the other hand, the significant house edge can discourage experienced players from betting too much money. Even with the big jackpots in sight, it is hard to justify a bet on Sudoku when there are so many other games with better RTP. And it is not that entertaining either. The theme is not amazing since it is based on a pure numbers game mostly played on newspapers. There are no special symbols or extra features that can break the monotony and make things more exciting, like in slots. The overall conclusion is that casino Sudoku can be a relaxing option for a few rounds, but it will not make the favorites list.
