Google Account Integration is Here!
Using Firebase, we've implemented Google Account integration!

Cloud Sync for a Better Gaming Experience
By linking your Google Account, you can now save your game data to the cloud instead of just locally on your device.
This enables the following seamlessly:
- 📱💻 Cross-device data sharing - Continue on your phone where you left off on PC
- 🔄 Data transfer when switching devices - Keep your progress on a new phone
- ☁️ Data backup - Your data is safe even if you lose your device
FreeCell Statistics Also Sync

The image above shows the FreeCell statistics screen. Your play count, win rate, win streaks, and more are all recorded.
By linking the same Google Account, this data can be shared across PC and mobile!
Supported Games
Google Account integration is currently available in the following games:
- ♠️ FreeCell - Statistics, favorite boards
- 🃏 Blackjack - Statistics
- 🧠 Memory Match - Statistics
- 🐙 Deep Sea Octopus v2 - Ranking scores
We plan to add support to future game releases as well.
