Sudoku - Free & Offline Review: No Paper Required
Sudoku is a popular form of numeral puzzles, originated in Japan. It’s all about digits. You need to fill the blank squares in the 9*9 field, according to the simple rules. Place digits from 1 to 9 in each row, column, and small square, so no digit is used twice in the same line or square.
We used to spend tons of paper trying to fill the tables with the numbers. Luckily, now we can download Sudoku - Free & Offline and do it on our phones or tablets.
In fact, Sudoku requires no special graphics at all. We only need a grid and some numbers already positioned in it, as hints. But the digital representation of it still offers some extras compared to doing it on paper.
First of all, the app offers prefilling of cells with digits we’re not sure about yet. These lesser digits appear in the corner of the cell we put them into, but still remain visible.
The second… There’s no second. The designers could have made the appearance look like old Japanese rice paper, with handwritten digits somehow resembling hieroglyphs, but they let us concentrate on the solution itself. We’re especially grateful for night mode available from the settings menu.
The mission of solving a Sudoku is to fill the 9*9 square with digits from 1 to 9. The condition is that in each column, each row, and each small 3*3 square each of the digits should only be used once.
The traditional way of solving Sudoku can be either deductive or inductive. You can either find the undoubtable partial solutions (for single small squares, columns, rows, or even single cells), and then extend your logic to the cells the solved one affects, or just guess about the numbers and develop your guessing until you encounter a contradiction. Then you go back to find out where you went wrong and do until all the digits fit.
As you select the field, the row and the column of it get highlighted. The digit that’s been used 9 times gets inactive. Not that it simplifies the process, but it gets you rid of unnecessary mistakes.
In this app the difficulty level is selectable. The easiest level offers the most hints, and the combinations are the simplest. The harder you go, the more time it takes to solve the puzzle. By the way. The app has a built-in timer that you can set on pause when you delay the solving.
The app keeps your stats, so you can see your results later, at any time. The results are stored in Google Play Games.
In the perfect world, you’d need just one tool, with pencil on one end and eraser on the other. Alas, our world ain’t perfect. So you have to operate the control panel below instead of just a pencil-like tool.
So, to fill a cell, you need to tap the digit off the panel, and then tap the cell you want this number in. The size of the digit depends on the mode: if blueprint mode is active, the digit will be small, and if it’s off, the digit is full-size. To remove digits, you need to activate the Eraser mode by tapping a bin icon and then tap the cell you want clear. But if the cells are blueprint-filled, you need to activate the blueprint mode along with the eraser.
Feel tired? And we haven’t started solving yet! Of course, you will get used to it once, but it’s a standalone puzzle to get right with the controls.
Replay Value 5/5
As the game has its built-in Sudoku generator, you don’t need to download new ones from its servers. The game is available for free, so you’re not limited in puzzles to solve. That makes its replayability nearly infinite. As we know, Sudoku has been around since 1980s, when Japanese magazines started offering it to the readers, and if we trace if further, it will turn out one more of Da Vinci’s inventions. And it will never be solved completely by machines because what we need is a process. OK, an industrial robot can easily raise a barbell that weighs a ton, but humans still attend gyms; the Sudoku story is like this.
So if you make a long way daily in trains or buses, or just want to give a couple of distracted hours to your brain, you have this game. It will never run out of puzzles, as well as it will never annoy you with ads popping up while you’re solving it – that’s the brief Sudoku – Free & Offline review and the best recommendation. Making out controls can take you a while, but the result is worth this.
So if your brain wants some playing with digits, download Sudoku – Free & Offline and feed your brain with it, so it will grow stronger.
