The season of Advent is nearly here! To celebrate I've made you this sudoku-themed calendar, but be careful as the numbers haven't quite stuck and some of the glue is still dryi... oh, oh dear... Well, let's see: there was definitely one window for each day from 1-24, these three were to be opened before the 16th and these snowball decorations... eh... Look, try it anyway and see how you get on!

• Normal sudoku rules apply
• Digits within cages may not repeat and sum to a unique total from 1 to 24 inclusive; any cage marked with a Christmas tree has a total smaller than 16
• Cells separated by a 'snowball' (white dot) must contain consecutive digits
