200 new levels and a new way to practice. • The map now runs to 400 levels, with over 1,000 new questions. • New: Review. From level 50, replay the questions you got wrong until you get them right, and see your weakest topics. • Clear the final level for a grand finale. • Every question has been re-checked, with clearer wording and better answer choices. • Finished all 200 levels? Level 201 is waiting for you.

Nature, not music. • The background music is replaced by a calm forest brook with birdsong. • Every sound effect is now a natural sound: water drops, splashes, wind, rain, thunder and birds. • The Music switch in Settings is now called Nature sounds.

Never lose your streak by accident. • All-new sound effects: richer chimes, a combo that climbs with every correct answer, and a bigger fanfare when you win. • Smarter reminders: a friendly nudge when today's Daily Challenge is ready, and a heads-up before your streak runs out. • Reminders stop on their own if you take a break — no nagging. • Bug fixes and stability improvements.
