Logic Masters Deutschland e.V.

You're almost there! Only four more Unowns to catch and you can go talk to Professor Oak to get your reward.

Fill the grid with digits from 1 to 9 so that :

• No digit repeats in a row or column (digits may repeat in a box).
• Digits in the center box indicate how many odd digits appear in the corresponding box (the top left cell for the top left box in the grid, and so on).
• A digit in a circle indicates how many digits have multiple occurences within that box (for clarity, this is not the number of such occurences).
• Digits outside the grid indicate how many segments of odd cells / even cells divide the corresponding row or column.
• All odd digits in the grid are orthogonally connected.
• Digits on a thermometer increase from the bulb on.

For extra challenge, solve without using the 4 above column 4.
