- 📅 Weekly XP — every game earns XP for playing and for skill. Your total XP across all games each week sets your overall rank, and the weekly top 10 win 💎 gems.
- 💎 Gems — also earned from daily play and streak milestones. Spend them in the Gem Store.
- 🎲 Practice — replay / practice rounds are just for fun and never count on the leaderboard.
