## FAQ

### Do these games save my progress?

Yes — scores and streaks are saved locally in your browser. Daily challenge completion persists across sessions so you can maintain your streak.

### Are these games suitable for all ages?

All games are family-friendly, browser-based, and involve no violence, ads, or in-app purchases. They are designed to be quick and engaging for all ages.

### What is a daily challenge?

Several games generate one shared board per day, the same for everyone, so completing it builds a streak. ChromaCode, EdgeSum, KnightMaze, ArcSwing, BloomStroke, and StackDrop all work this way; come back the next day for a fresh board.

### Can I keep playing after the daily puzzle?

Yes, for several titles. StackDrop has an unlimited mode, and the Visual Memory and Number Memory tests run as long as you keep succeeding. The pure daily puzzles reset with a new board the following day.
