Your rocks
Your first rock lands when you finish a round today.
You get a rock for each day you finish at least one round of any practice. A day when Today's set has every answer right gives a gold nugget instead. Rocks are saved in this browser and sync across devices when you sign in.

About your history
Days visited counts each local calendar day once, including days you only explore. Days off do not reset your total. Earlier activity is not used to fill in visits.
Saved practice rounds counts the rounds still in your latest 100 practice and lesson activities. It is not a lifetime total. Completed lessons and favorites are kept separately. Unfinished practice rounds are not saved.
