What's New in Sudoku Neo
1.4.1
September 2, 2026
Fixed: the Easy, Hard and Expert daily leaderboards now accept scores - they were configured but never published to players, so results sat pending. Any past result already on your device will submit on its own. Also: a clearer message when a leaderboard genuinely isn't ready yet, instead of looking like a connection problem. And the app may occasionally ask for a rating after a daily win.
