Un jeu de puzzle intrigant qui vous tiendra accroché à votre téléphone pendant des heures

You have a grid of squares. Your job is to draw lines between the centres of horizontally or vertically adjacent squares, so that the lines form a single closed loop. In the resulting grid, some of the squares that the loop passes through will contain corners, and some will be straight horizontal or vertical lines. (And some squares can be completely empty – the loop doesn't have to pass through every square.)

Some of the squares contain black and white circles, which are clues that the loop must satisfy.

A black circle in a square indicates that that square is a corner, but neither of the squares adjacent to it in the loop is also a corner.

A white circle indicates that the square is a straight edge, but at least one of the squares adjacent to it in the loop is a corner.

(In both cases, the clue only constrains the two squares adjacent in the loop, that is, the squares that the loop passes into after leaving the clue square. The squares that are only adjacent in the grid are not constrained.)

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.
