Serpentino is a free puzzle game developed by Verschueren Geert for Android 9.0. The main objective of the game is to find a hidden snake in the grass. The snake is made up of 36 body parts, and the head and tail are already given as hints, leaving you with 34 remaining parts to find.

The game is played on a 9x9 grid, with each 3x3 sub grid containing a number indicating the number of body parts in that sub grid. Additionally, the numbers outside the grid indicate the amount of body parts for that specific row or column. It's important to note that the snake likes space and won't touch itself again, which adds a level of difficulty to the game.

Overall, Serpentino is a challenging puzzle game that will put your problem-solving skills to the test. Good luck finding the hidden snake!
