It's the compromise option that pleases nobody!
I think this would be a better option than the preview. You can't just include the preview as an option, because that would inevitably turn into the "optimal" way to play the game and a lottt of players would feel pressured to use that. You'd end up with a situation where players would turn the score preview on thinking they need every edge they can get and accidentally churning half the fun out of the game in the process. It's a dangerous line to walk!
Calculator though? That adds some extra gameplay (punching your numbers in), it requires enough extra effort that only dedicated players would feel the need to use it, and even then only in dicey situations. And, frankly, I kinda find the idea of a game literally incorporating a calculator into the gameplay loop to be delightful. Balatro's maths isn't even particularly complicated, so you'd only need + x and = buttons.
Potential counterarguments:
There's no point to this, you already have a calculator on your phone
Yeah but a balatro themed calculator would be adorable. Also having it embedded into the game means you don't have to switch applications, and it signals to a player that this is a valid way to approach the game's challenges.
I'm bad at maths! I won't be able to do the calculations!
You were bad at Balatro as well when you first started out. Having a calculator in the game will actively make you better at maths. Can't get better at something without doing it!
Maths isn't fun!!!
Skill issue. Incorrect. Ms Frizzle would be disappointed in you.
I really want a score preview though
Mod the game, then. Score preview is the kind of thing that I think really is so dangerous to the general experience of the game that it's risky to include "officially" in any capacity. I really think it is for the better that there's a large barrier to accessing it, such so that players who absolutely cannot live without it have an option to get it, but players who are kind of ambivalent don't feel like they need it.
This is stupid
Maybe so! Maybe so.
