- This game starts out easy, but quickly picks up in difficulty. To collect all 21 marbles some brain stretching and patient strategizing will be required.
- It's fun to roll the marbles with real physics, break them and put them back together.
- It's a sudoku-like puzzle that is quick and colourful. You won't fall asleep solving it.
- It's designed for kids but is known to be enjoyed by adults.
- 21 Marbles is appropriate also for a school setting as it doesn't include unwanted distractions and has a very explicit and friendly measure of progress. (e.g. "Have you got a transparent marble yet?")
- 21 Marbles features attractive marbles that motivate kids to continue even when the going gets tough.
- The levels are different every time you play, so while the game can be completed in a few days, it can be played again and again and never gets old (however see the next point).
- The game has an ending and doesn't try to get you or your child hooked forever. No addiction techniques whatsoever are employed.
- There are two kinds of music - wind and string instruments. The sound and music can be turned off independently.
- You can share your progress with screenshots, after passing a small "maturity" test.
