You can find more screenshots for phones and tablets and the uses card themes as .svg files here

There is a DummyGame class with a lot of comments, if you want to add a new game. I hope it's good enough for that!

I learned Android and Java by myself using e-books and browsing Stack Overflow for solutions, so please don't expect too much from my source code :D

It is a very simple game, but customizable and with some neat functions like hints. Here is my Google Play description:

Highly customizable: There are 6 different looking card sets in this game, 12 different card backgrounds and 6 different background colours. So you have a large choice to customize your experience!

Set up difficulty: You can set up the difficulty for Klondike, Spider and Golf in the settings!

Automatic saving: The current game will be saved every time you pause or close the app. So you can continue your game where you left it!

High Score list: When winning a game, your score will be saved in a list of up to 10 high scores.

Game features: This game has a undo function to take back up to 20 card movements. A hint function shows you up to 3 possible card movements at once.

Left handed mode: There is a option for left handed people to mirror the card positions to the left side of the screen.

No ads: This game is completely free without ads, tracking or something else. Just have fun :)

Landscape and tablet support: You can switch to landscape mode, this is better for larger screens. It is also possible to lock the orientation in the settings

Installation Guide

The instructions to compile this app are very easy. Just download the project and open Android Studio. Then go to File -> Open -> Navigate to the download location -> Choose the folder -> If you try to start the app, Android Studio should install all necessary dependencies and you are ready to go.

Or alternatively, follow this guide to compile the app on the command line: https://developer.android.com/studio/build/building-cmdline.html

I already found a lot of copies which simply removed my "About Game" screen and changed some graphics.

To-Do List

• Add more games (frecell, spider and yukon)
• Improve the settings to use fragments
• Add even more games (Simple Simon, Golf, etc)
• Add the card themes from Kpatience, if their license is compatible to mine. (I asked the main dev from Kpatience, the licenses of the themes aren't clear, and there are no links to the authors of them...)
• Add a color chooser for background color
• Improve the Highscores to a Statistics Activity (including date stamps)
• Find the reason why the game activity gets created two times when changing the screen orientation in game
• Add a button to mix the cards if no movement can be done
• Add 'Grandfathers Clock'
• Add a Custom game maker, maybe
• Add a 'poker standard' card theme and 4 color themes
• Add a option to Yukon to play on same suits, instead of different color (like Russian Solitaire)
• Also save high scores when canceling a game
• Add an option to set up appearance for each game indivially
• Implement "Tap to select/move cards"
• Add custom images for backgrounds (Would require additional android permissions, I don't really want that)
• Add drag and drop feature to change the order of the games in the main menu
