Here's another older puzzle of mine, that didn't get published yet. I made it as a Secret Santa present back in 2021 for one of the Vietnamese puzzlers on CTC discord, hence the 'Santa' and Vietnamese references in the puzzle - the flag, the international dialing code (+84), etc.

The Rules:

• Normal Sudoku rules apply.
• The adjacent digits in the green Christmas trees are Vietnamese whisper digits, and must differ by at least 4.
• The digits in the yellow star of the Vietnamese flag are a consecutive set of digits, but may appear in any order.
• The digits in the red cells of the Vietnamese flag must sum to a total of 84.
• Digits separated by a white snowflake must be consecutive. Not all snowflakes are given - some of them have melted! :)
