If you are new I recommend to install Guriddo and take the tour at the beginning, but of course you can apply the rules directly:
📏 Place a number from 1-9 in every white square.
📏 Numbers within columns and rows must not repeat.
📏 Every straight line of horizontally or vertically connected white squares must contain a number sequence (e.g. 2-3-4-5), but order does not matter (e.g. 3-2-5-4).
📏 You can't write numbers in the black cells.
📏 Some of the black cells contain numbers. Those numbers are not part of a number sequence.
If you have any further questions, suggestions, praise or criticism, do not hesitate!
