For example, if we have a valid Sudoku grid and simply relabel each number with one of the other numbers — say, take every 1 and replace it with a 5 and vice versa — we clearly end up with.

I made a Python Script to Automate a Sudoku Game on Android after watching Engineer Man’s Videos on Youtube doing the same for different games.
The script can be divided into 5 parts
- Connecting to an Android device using ADB, and getting the screenshot of the game from it
- Using Pillow to process the screenshot for pytesseract
- Using pytesseract to extract the Sudoku Game Grid to a 2D List in Python.
- Solving the Sudoku Game
- Sending the solved input to your Android Device using Python
Out of the 5, I will be focusing mostly on 2,3 & 5 as 1 & 4 are topics that have been extensively covered.
Link to the game I automated: https://play.google.com/store/apps/details?id=com.quarzo.sudoku
The complete code is available on the following repository:
You can also watch the script in action on:
1 (a). Using ADB to Connect to your Device
Most of the tutorials on internet use Wired ADB, which discourages many people from using this method. I will be using Wireless ADB, which isn’t very difficult to setup.
Go to your Phone Settings > System > Developer Options (This might vary in different phones, so if it is not the same in your’s, look it up on the internet)
Turn on Android Debugging and ADB over Network.
ADB over Network
Note the IP Address and Port shown under ADB over Network
Install ADB on your computer
Go to your command-line / command prompt and enter
Use the IP Address and Port from Step 3
When connecting for the first time, you will need to authorize the connection on your phone.
Your device should be connected to your PC over WiFi.
1 (b). Using ADB with Python (pure-python-adb)
You can define the following function to connect to the first ADB device connected to your computer using Python
We will be using this function later to return an instance of
ppadb.device.Device which will be used to take a screenshot, and send input to your device.
1 (c). Taking a Screenshot and saving it
pure-python-adb makes it very easy to capture a screenshot of your device. The
screencap function is all that you need to get the screenshot. Use Pythons File IO to save it to `screen.png`

2. Processing the screenshot with Pillow
In the captured screenshot, the accuracy of any OCR will be very low. To increase accuracy, I used Pillow to process the screenshot so that it only shows the numbers in black color on a white background.
To do that, we first convert the image to grayscale (or single channel) using
image.convert('L'). This will make the convert the colors to shades of greys (0-255).
After this, we need the numbers (which are the darkest, or very near to black) in black color, and the rest in white. For this, we use
image.point() so that all the greys > 50 become white (255) and the rest (numbers) become 0. I also increased the Contrast and Sharpness a bit to be on the safer side.

3. Extracting the numbers from the image using pytesseract
Using pytesseract on the whole image might give us the numbers, but it won’t tell us in which box the number was present. So, I use Pillow to crop each box and then use pytesseract on the cropped images. Before using pytesseract, I defined some functions to give me the coordinates of each box and to give me a cropped image of each box.
Since Sudoku has a 9x9 grid, I use two for loops from 0 to 8 to loop over each box. The pytesseract wasn’t accurate enough on the default configuration and I had to pass the config
--psm 10 --oem 0.
--psmargument defines the Page Segmentation Method.
Treat the image as a single character. This seemed most appropriate since I am passing cropped images of each box.
--oemargument defines the OCR Engine Mode.
Legacy Engine Only.
The following function will extract the numbers from the passed
image and return a 9x9 2D List with the numbers.
4. Solving the Sudoku Game
Now that we have the 9x9 Sudoku, we need to solve it. Solving Sudoku is a topic that has been covered a lot, and I also copied this code from geeksforgeeks.org.
5. Sending the solved input to your Android Device using Python
To send the input, I first filtered out the input from the solved Sudoku Grid,i.e, only send the values which were missing. I used the
get_coords function from earlier to get the coords of each box and then calculated their centres. I sent a touch at that centre using ADB, and then sent over the solution.
Running the code
All the code that I wrote is in functions and they are called one by one. Note that the grid that I get in step 3 isn’t passed directly to step 4. I use
deepcopy to create a copy of it, so that I can compare the solved grid with the unsolved/original one in step 5.
An Easy Quilt Pattern for the Beginning Quilter
This post contains affiliate links for which I receive compensation.
The Single Irish Chain Quilt pattern is an easy beginner quilt. 5 things every email needs. Set in horizontal rows it's all rectangles and squares, ideal for a new quilter to practice rotary cutting skills and to perfect that scant quarter inch seam allowance.
But set it on point, add setting triangles and the design is transformed.
All of the images on this page are designed and drawn in Electric Quilt, a quilt design software that is available for both PCs and Macs.
I use it to design all my quilts and the illustrations here on the website. It's easy to learn, easy to use and makes auditioning colors and fabrics a snap.

The Building Blocks
This two unit quilt pattern is characterized by a single chain of squares that form a grid around an open area. Pieced units nine patches alternate with solid squares to form the pattern.
The open spaces are ideal for showcasing your applique, hand or machine quilting or new set of machine embroidery designs.
You can choose from one of several pieced designs to create this pattern. These different block(s) provide a way to increase or decrease the amount open space to suit your needs.
The Basic Nine Patch
This nine-patch is simple to construct from individual squares. But if you need exact multiples of it, strip piecing is even faster and easier.
This unit creates the smallest possible open space, probably too small for most fancy machine quilting or applique, and is based on a 3x3 grid.
Click here for several different ways to make a Nine Patch.
Set in straight rows with an alternating solid square..
Or in an on-point setting..
To complete this type of layout, you need to also cut and sew setting (QSTs) and corner triangles (HSTs) to fill out the design.
Country Lanes Quilt Block
Other common names: Cross in the Square, Pennsylvania
Just like it's cousin, the Double Irish Chain, this block is based on a 5x5 grid and creates an open space 2/3's larger than the previous ninepatch block.
Click here to learn how to make this block.
First a horizontal layout..
And now an on-point layout..
The Double Nine Patch
Other common names include: Single Irish Chain, Golden Steps, Puss in the Corner
Simply a nine patch made from nine patches. It creates an open space equal to its 9x9 grid.
It can be set in one of two ways:
- With a solid alternate square or
- With a plain sashing strip and a nine patch for the cornerstone. The sashing is cut a width equal to the unfinished nine-patch square.
Our examples use a solid alternating square.
Set in horizontal rows..
Set on point..
To jazz things up a bit, why not add two extra fabrics.
Choose a light fabric for the small nine patches, another fabric (pink) for the alternate squares in the double nine patch, and a third color (blue) for the alternating squares.
Did you notice..?
All the straight sets for our Single Irish Chain had odd-numbered blocks in the rows and column. In the diagonal or on-point layouts it didn't matter.
Symmetry was maintained.
Make the Single Irish Chain design your own
The pieced units used to create a Single Irish Chain Quilt all have a single row of squares that forms an 'X' and runs from corner to corner. These squares needn't be all the same size. Two more that work to create a single Irish Chain are:
Pennsylvania, Criss Cross Quilt,Simple Cross, Single Irish Chain
Nine Patch, A Plain Block, Sheepfold Quilt, Irish Chain
Remember that to maintain the quilt design's symmetry in a straight set, both rows and columns need an odd number of blocks. There is no limitation for an on-point layout.
Finally, though a single Irish Chain quilt pattern is traditionally constructed with just two fabrics, there is no reason not to use up your scraps. Just be sure that there is enough contrast in value between the background fabric and chain fabrics so that the design is prominent.
