Calvinball

I made the initial iteration of this puzzle 6 months ago but it didn't quite feel right. Even though you could get different working solutions, the rules themselves never changed, and that wasn't truly in the spirit of Calvinball. Also, it was quite hard for a 6x6. But if you'd like to play that original version you can do so here: 6x6 Calvinball

Rules

Other kids' puzzles are all such a bore! They've gotta have rules and they gotta keep score! Calvinball is better by far! It's never the same! It's always bizarre! You don't need a team or a referee! You know that its great, 'cause it's named after me! If you wanna have fun! Play Calvinball! da da buh dum! The only permanent rule in Calvinball is that you can never play it the same way twice!

Normal sudoku rules apply.

There are red (hollow) and green (solid) lines, choose one of the following rules to apply to red lines. The other rule will apply to green lines.

• Entropic: Any set of three sequential cells along an entropic line contains one digit from each of (123), (456), and (789).
• Modular: Any set of three sequential cells along a modular line contains one digit from each of (147), (258), and (369).

There is a blue dot and a pink square, choose one of the following rules to apply to the blue dot. The other rule will apply to the pink square.

• X-Domino: Digits separated by this shape sum to 10.
• V-Domino: Digits separated by this shape sum to 5.

Note: Because of the varied nature of the ruleset, there is no solution check with this puzzle. I hope you enjoy it!
