Hint
Reveal a hint
The count looks wrong because some balls are hidden. Try tilting or shaking the phone to make them appear.
Why It Works
The puzzle hides a few balls so the visible count is too low. Shaking or tilting the device rolls out the hidden balls, and counting everything together gives 10.
