Pencil marks now clear themselves. When a square gets solved, that number disappears from the notes in its row, column and box — including when an opponent claims it. Rules & Scoring is now reachable from any score breakdown, so you can check how points work without leaving the game. Retired the animated player colors and added eight new premium ones: Obsidian, Platinum, Champagne, Sapphire, Ember, Peacock, Orchid and Bronze. Gift amounts now start at the actual minimum instead of an amount that would be rejected. Fixed the board resizing slightly when you finished a solo puzzle.

Your name, your crew, better referrals. • Referrals now reward BOTH of you — you and the friend who uses your code each get 20 Quickets. • Referral codes now stay valid for 30 days instead of 3. • Anyone who joins with your code is added as a friend automatically, and you'll get a notification telling you who joined. • Pick a display name when you sign up, so friends and referrals show the name you chose instead of a placeholder. • Kosudoku now runs on iOS 17 and later, so more of your friends can play. • Assorted fixes and polish.

Fresh new look with an updated board color scheme, plus performance improvements and bug fixes. Thanks for playing Kosudoku!
