Innovative, stratospherically smart, and sublimely designed. Even the last two deductions are magnificent.
Recently recommended on CTC Discord.
It fully deserves to be included in the next "CTC Cosmic Hits" book.

A hidden gem! It took me a while to get the rules established in my head and discover the tricks but I'm glad I stuck with it!
Small thing regarding the rules: the last one might read better simply put as "All possible diamonds and triangles are given. Not all dots are given."
EDIT: here is a new link for SudokuPad which includes the solution in case you want it: https://sudokupad.app/ak1iizh8ln
