Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). A cell containing a diamond is part of a group of numbers of the same parity connected by edges, and the number inside the diamond indicates how many numbers of the same parity (including itself) form this group. (For example, a diamond containing a 2 must be connected by its edges to only one other even number besides itself; that is, all other edge neighbors of these two numbers must be odd.)

GAS – We’re there at the drop of a hat

Sudoku by clover!

(This post is part of the Genuinely Approachable Sudoku (GAS) series.)
UPDATE from clover!: Good morning, friends! I hope you all enjoyed Bill’s April Fools CAPTCHA earlier today. Now that we’ve got that out of our systems, here’s today’s real GAS: a classic sudoku. Normal sudoku rules apply. And that’s it!

UPDATE 2 from clover!: I hear you, I hear you. “Clover, something is wrong. Clover, we want more digits. Clover, our lack of creativity is preventing us from solving your beautiful sudoku.” Fine, I’ll give you one more digit, but you’re going to have to work for it. 😤 Here’s another classic sudoku that I set extra-special just for you. Normal sudoku rules apply. Once you’ve solved it, simply take the digit from r2c5, and place it in r1c1 in the previous sudoku. That should help you out a bit. And that’s it!

UPDATE 3 from clover!: You may think I’ve singlehandedly tripled the GAS team’s count of non-unique sudoku in just a few hours, but you’d be wrong. I’ve actually quadrupled it. Are you almost ready to solve the puzzle, friends? Here you go: Normal sudoku rules apply. Solve this puzzle, and then take the digit from r1c9, and put it into r5c2 in the previous sudoku. That ought to do it!

UPDATE 4 from clover!: Mea culpa, I knew I was forgetting something. Regarding the hats and/or dinosaurs: to earn them, simply take the digit from r9c9 in the first sudoku I posted this morning, and place it in r7c3 in the sudoku immediately preceding this post. The timer stops when you successfully solve all of the sudokus in this post. 😉
