Solitaire
The classic Klondike card game, fully offline. A built-in solver tells you whether the game can still be won.
The game
Solitaire is the classic Klondike card game: build four piles from Ace to King, one for each suit. Move cards between the seven columns, turn over the hidden cards, and draw from the stock when you are stuck.
A built-in solver keeps an eye on every game. The colored lamp shows whether the game can still be won, so you know right away when a move has led to a dead end.
Three difficulty levels
Easy
Draw 1 card at a time, unlimited passes through the deck. Every deal is winnable.
Medium
Draw 3 cards at a time, unlimited passes. Every deal is winnable.
Hard
Draw 3 cards at a time, only 3 passes through the deck, and a random deal.
Left-handed mode
Puts the stock and waste on the left side of the table.

Why Solitaire isn't on the Google Play Store
Google currently enforces highly demanding and complex requirements to publish new apps (such as mandatory closed testing phases with at least 20 people for 14 days, rigorous identity verification, and heavy administrative overhead). Because we build apps purely for our own enjoyment and want to keep it simple, we prefer to share the app with you directly.
How to Install the App
- Directly on your phone: Open the downloaded file. If prompted, allow your browser or file manager to "Install unknown apps" from outside the Google Play Store. Google started blocking this way of installing APK files.
- Via your computer: Connect your phone to your computer with a USB cable and install the app using Android Debug Bridge (ADB).
By downloading you agree to the Privacy Statement & Disclaimer. Use is entirely at your own risk.
How to install an APK directly on your phone
- Tap the download button above and wait for solitaire.apk to finish downloading.
- Open the file (via your notification shade or the Files app).
- Android will ask permission to install unknown apps. Tap Settings and enable "Allow from this source" for your browser or file manager.
- Go back and tap Install.
- Open Solitaire when installation completes.
Installing apps from outside the Play Store is a normal Android feature. You can turn the "unknown sources" permission back off afterwards if you prefer.
How to install an APK via your computer
The cleanest, safest, and most secure way to install an APK file—without modifying your phone's mobile security settings or enabling "Unknown Sources"—is via ADB (Android Debug Bridge) from your computer. This is an official command-line utility supplied by Google for Android developers.
Step 1: Download ADB on your computer (The fastest way)
You do not need to install the massive Android Studio suite. Google provides a lightweight, standalone package called Platform-Tools.
- Windows: Download the official Android SDK Platform-Tools for Windows.
- Mac / Linux: Download the zip package above or install it instantly via your terminal line:
- Mac (via Homebrew): Run
brew install android-platform-tools - Linux (Ubuntu/Debian): Run
sudo apt install adb
- Mac (via Homebrew): Run
Note: If you downloaded the ZIP file (Windows/Mac), extract it into an easy-to-reach directory, such as C:\platform-tools or your Desktop.
Step 2: Prepare your Android phone
- Open the Settings app on your phone.
- Go to About phone (or System > About).
- Tap Build number 7 times rapidly until a notification pop-up says: "You are now a developer!".
- Return to the main Settings menu, open the new Developer options panel, and turn on USB debugging.
Step 3: Install the APK file
- Connect your phone to your computer using a USB cable.
- Look at your phone's screen: a prompt will ask "Allow USB debugging?". Check the option for “Always allow from this computer” and tap Allow.
- Move your downloaded APK file directly into the folder where you extracted the platform-tools files.
- Open Command Prompt (CMD) on Windows or Terminal on Mac/Linux, and change directories to that folder (e.g., on Windows, type:
cd C:\platform-tools). - Run this command to verify your computer properly detects your device:
(If you see a serial number followed by the word 'device', you are connected successfully!)adb devices - Run the installation script command:
adb install solitaire.apk
When the terminal returns a Success message, the app is fully installed on your device and ready to launch!
How to play
1. Start a game
Tap New game and choose New deal or Restart this deal. The difficulty is set in Settings and is remembered. The clock starts with your first move.
2. Build the columns
Put a card on a card one rank higher and of the opposite color (red on black, black on red). Only a King, or a run starting with a King, may go into an empty column.
3. Draw from the stock
Tap the stock to turn over 1 or 3 cards onto the waste. When the stock is empty, tap it to turn the waste over again (unlimited on Easy and Medium, 3 passes on Hard).
4. Fill the foundations
Build each foundation up by suit, from Ace to King. You win when all 52 cards are on the foundations.
5. Watch the lamp
After every move the solver checks whether the game can still be won. Tap the lamp for details; when it turns red, use Undo. Hint highlights a move (or the stock) that leads to a win.
Scoring & lamp
| Action | Points |
|---|---|
| Waste to tableau | +5 |
| Waste or tableau to foundation | +10 |
| Turn over a tableau card | +5 |
| Foundation to tableau | −15 |
| Recycle the waste | −100 (Draw 1) / −20 (Draw 3) |
| Time | −2 per 10 seconds |
| Win (games longer than 30 s) | bonus of 700,000 ÷ seconds played |
The score never drops below 0.
The winnable lamp
| Lamp | Meaning |
|---|---|
| 🟢 Green | The game can still be won from here. |
| 🔴 Red | Proven that the game can't be won anymore. Try Undo. |
| 🟡 Yellow | Too complex to decide quickly (rare). After a few moves it usually turns green or red. |
| ⚪ Gray, pulsing | Checking… |
The solver knows the face-down cards (like "thoughtful solitaire"). Yellow mostly appears at the start of Hard games.
