YuYuan: Puzzles & Drawing

I originally made YuYuan for my daughter. It brings together 34 mini-games, creative activities and useful little tools for iPhone and iPad. Learn, create and play at your own pace. ATTENTION, MEMORY AND LEARNING • Spinning Schulte: Tap numbers in order on independently rotating rings. Choose a timed 1–50 challenge or slower, untimed 1–25 practice. • Oracle Bone Buddies: Explore 1,530 reference cards pairing oracle-bone forms with Chinese labels. Search, zoom, mark familiar cards and match 4, 6 or 8 pairs. Browse common characters first or use original card order. • Number Hunt: Find 49 or 25 numbers in order among distracting letters and irregular cells, with two-minute rounds and saved best times. • Collision Tracking: Remember 1–4 targets among nine bouncing balls, then identify them when motion stops. • Dual Ball Tracking: Follow one target in each of two six-ball rings for 20 seconds, with four difficulty levels. • Attention Training: Remember targets among 19 dots on seven overlapping circles and follow their turns. Choose sports-ball appearances. • Color & Dots: Match colours and dot counts across 24 dice. • Pi Memory and Flash: Recall digits of pi or a briefly shown number sequence. • Hide and Seek, Counting Blocks and Chaos: Remember positions or find numbers in order. • Pick Right Color, Emoji and Match Emoji: Match colours, find emoji or flip matching pairs.

All activities are free, with no ads, subscriptions or account required. Progress, preferences and imported audio stay on your device. Photos access is requested only when saving an image. The home menu includes the Privacy Policy and a shortcut to the app’s system settings for language preferences. Interface languages: English, Simplified Chinese, Traditional Chinese, Japanese, Spanish and Portuguese. Oracle-bone labels retain their original Chinese text.
