Your streak now carries forward correctly every time you play. We also restored streak-at-risk reminders, so you'll get a heads-up before a hard-earned streak runs out. Keep that streak alive! ### 5.0.1 — 2026-08-16 Landscape Mode for iPhone Rotate your iPhone and keep playing — the board, keypad, and tools now resize to fit landscape beautifully. Zoom mode and hints have been redesigned for the wider view too. Bug Fixes - Fixed an issue where the number pad could keep showing a digit as unavailable even after undoing the move that freed it up again, particularly after restoring a bookmark - Refreshed the "Powered by One Thum" branding on the launch screen - General stability improvements Thank you for playing DokuDoo! ### 5.0.0 — 2026-08-01 What’s new in DokuDoo • A redesigned win screen — clearer score, streak, and share • Clubs — play together on Today, Week, and All-time boards • Better iPad layouts for the board and play experience • Home and continue fixes so completed puzzles stay completed • Polish across Boards, Friends, Stats, and Settings Thanks for playing. Keep that streak going. ### 4.2.4 — 2026-06-26 What's New in Version 4.2.4 Score & Timer Fixes We fixed an issue where the score shown when you finished a puzzle could differ from what appeared on the daily leaderboard. Completion, stats, and leaderboards now all use the same scoring formula. Timer Improvements The timer in the game header now always matches your final completion time Restarting a puzzle resets the board but keeps the clock running — your total time on the puzzle still counts toward scoring Thank you for playing DokuDoo! ### 4.2.3 — 2026-06-19 Better Layouts for iPad We've heard your feedback about the home screen feeling a little squeezed on iPads, so we've updated the layout! What's Fixed More Breathing Room: The difficulty selection cards on the iPad now use a clean, stacked column layout just like the iPhone, giving the text and points plenty of room to breathe. Responsive Rotations: Whether you're playing in portrait or landscape, the layout adapts perfectly. Scrollable Content: If you rotate the iPad to landscape, the home screen now elegantly scrolls to ensure you can see all the difficulty options without anything getting cut off or clipped. Technical Improvements Maximum width constraints added for larger screens to keep the UI perfectly centered Adaptive ScrollView implementation for portrait/landscape sizing Keep solving those daily puzzles!
