how gems & hearts work
gems are earned by answering questions correctly. harder questions = more gems. speed bonuses for fast answers.
hearts are spent when you get an answer wrong in solo play. run out of hearts and you can't play until tomorrow (or refill with gems).
free players earn up to 180+ gems/day (more with speed bonuses) and get 5 hearts + 3 rounds per day.
