Our Guarantee: You Will Be Absolutely Stunned By This Puzzle

Today we feature one of the best puzzles we have ever seen. It's called Squares And Circles and it's a debut on the channel for Burning Curtains. It makes Simon laugh in admiration of its genius. Give it a try at the following link:

Rules:
Normal sudoku rules apply. Digits cannot repeat within a cage. The digits in each cage sum to a square number (eg 0, 1, 4, 9...). Cells separated by a white dot must contain consecutive digits. There are 9 hidden zeros in the grid, which count as 0 for the purposes of cage sums and white dots. The hidden zeros appear once in each row, column and 3x3 box and consist of all the digits 1-9 once each. Hidden zeros may not repeat within a cage.

Sam Cappleman-Lynes has made an extremely clever 6x6x6 set of puzzles. We have released a solution video for this puzzle on Patreon and you can try to solve it yourself at these links (one to our software, one to penpa (which allows you to increase the size of the grids):
