How gems work
• Earn gems from daily play, streak milestones, referrals and the weekly XP leaderboard.
• Cosmetics (frames, flair, themes) are yours forever once bought — equip and re-equip any time.
• Hints work in practice mode only, so daily leaderboards stay fair.
• A Streak Freeze protects your Day streak through one missed day; Streak Restore brings a broken streak back to your best.
