This puzzle is inspired by a puzzle named "Ball Pit" by Marvin which featured on the CTC channel. Hopefully you guys enjoy this one too!! You can watch the video here:
Rules:
1. Normal sudoku rules apply.
2. Digits in a white circle must appear in the four surrounding cells.
3. Cells separated by an X must sum to 10. Cells separated by a white dot must contain consecutive digits. Cells separated by a black dot have a 1:2 ratio. Not all possible Xs and dots are given.
Do have a go!

I got really stuck for way too long on this one. I watched the Ball Pit video on CTC one more time (I've seen it before, back in the day), but that only helped me so far. Eventually I started to see how to use the dots to help me make progress again and that carried me to the end.
