How to play
Look at the clues and Sprig’s idea. Choose the example that gives a different answer from that idea. Watch the rule change, then check three new examples. An example that both ideas accept or both reject cannot tell them apart. Four worlds contain 24 curated lessons. Children can replay completed lessons.
Free lessons, purchase and restore
Six complete lessons are free. RuleSprout Lifetime unlocks access to all 24 lessons for US $5.99 as a one-time purchase with no subscription. Worlds still open in learning order. Open Parent Area, hold the leaf for three seconds, then tap GROW. Choose RuleSprout Lifetime to see Apple’s current localized price, Unlock Full Game or Restore Purchase. Restore with the Apple Account used to buy. A pending purchase unlocks after Apple approves it.
Progress and offline play
Progress saves automatically on this device after important steps. Continue resumes a stable lesson checkpoint. Core gameplay works offline; Apple product loading, purchase and restore require an internet connection. Purchase restoration restores access, not lesson progress. Avoid deleting the app to troubleshoot a purchase, because local progress can be lost.
Display and support
The app follows system appearance, text size and Reduce Motion. Silent play includes all lesson feedback. A parent can email the app version, device model and a short description of an issue. Please do not include children’s personal information.
