Sudoku: House of Secrets

Play Sudoku at your pace: choose Classic mode or a family mystery in Maracaibo across three chapters and nine encounters. Pick Easy, Medium or Hard, keep pencil notes, undo moves and learn through logical explanations. Each puzzle includes three free hints. You can then voluntarily complete a rewarded ad for one additional hint, subject to availability. A separate bottom banner may appear while you play. The one-time Remove Ads purchase removes the banner and includes unlimited hints without videos; purchases can be restored. No subscription. Puzzles and local saves work offline. Ads, purchases and purchase restoration need an internet connection. No accounts, lives or energy. English and Spanish. Progress stays on your device without sync.
