Singles: A Geeky Puzzle Game

You have a grid of white squares, all of which contain numbers. Your task is to colour some of the squares black (removing the number) so as to satisfy all of the following conditions:

No number occurs more than once in any row or column.

No black square is horizontally or vertically adjacent to any other black square.

The remaining white squares must all form one contiguous region (connected by edges, not just touching at corners).

This app is integrated with Alphonso software. Subject to your permission, the Alphonso software receives short duration audio samples from the microphone on your device. The audio samples never leave your device, but are irreversibly encoded (hashed) into digital "fingerprints." The fingerprints are compared off-device to commercial content (e.g., TV, OTT programming, ads music etc.). If a match is found, then appropriate recommendation for content or ads may be delivered to your mobile device. The Alphonso software only matches against known audio content and does not recognize or understand human conversations or other sounds.
