This update brings opening study, focused review, and practical play closer together, with a cleaner experience across iPhone and iPad. MORE MEANINGFUL OPENING STUDY • Learn what comes next with follow-up plans for all 20 guided openings. • Find lessons with search, colour filters, and favourites. • Explore alternative moves in Study and Quiz, and open a related lesson when a matching opening is available. • Revisit difficult positions in a dedicated review screen, with dates, times, and learning results. • See quiz results that distinguish answers without help, hints, and wrong attempts. • Play against the AI directly from the final lesson position to put your opening knowledge into practice. • Enjoy clearer quiz completion dialogs and a redesigned settings sheet. BETTER PUZZLES AND MISTAKE REVIEW • Request a one-move hint: an arrow shows your next move without revealing the whole solution. • Hint-assisted attempts are recorded separately from unassisted successes. • Pause and resume puzzles, and return to difficult ones for focused practice. • Use refined puzzle search, status filters, and theme chips. • Read mistake feedback without pushing the surrounding controls out of place. • Follow clearer instructions, recommended continuations, and navigation in Mistake Review. A CLEARER LEARNING HOME • Jump back into unfinished learning. • See today's puzzles, opening reviews, successful retries, and assisted attempts with simple icons and counts. • Get a cleaner home screen without empty practice sections, plus a clearer first-launch guide. MORE ROOM FOR THE BOARD • Improved board and control layouts for different iPhone and iPad sizes. • More compact engine analysis, with expandable extra lines on smaller screens. • Consistent move buttons, typography, spacing, settings sheets, and dialogs. • Subtle touch feedback where it helps, plus animated dismissal of introductory guidance. ANALYSIS AND STABILITY FIXES • Fixed evaluation graphs that could reverse the apparent advantage when showing mate scores. • Reduced flickering in the engine and move list when turns change. • Prevented distracting layout shifts when moves are added, filters change, or the active player changes. • Improved spacing for longer translations in game results. • Improved analysis cancellation, timeout handling, and recovery after deleting a saved game. LANGUAGE IMPROVEMENTS • Filled gaps in key interface translations across English, Korean, German, Russian, French, Spanish, Japanese, Chinese, and Portuguese. • Made learning messages and puzzle terminology more consistent, with more natural wording and cleaner punctuation.
