There, Sapphire Blue offers you an interesting game. You will need to complete 16 tasks within 60 minutes. For each correct answer the Sapphire Blue will take off some of your clothes. If you answer all the questions and meet the deadline, you'll see a Sapphire Blue fucking her cunt with a thick black vibrator. The question will be from different areas of science, so be careful. If you doubt your knowledge, use the internet to find the information you need. Do you want to see a Sapphire Blue achieve multiple orgasms! Then let's start playing now.

The math problems are insultingly easy at first, like 2+2, and then suddenly you're doing 17x8 in your head while this pixel girl with huge tits stares at you with that bored expression. Miss Rain, they call her. The whole thing runs on this weird keyboard setup where you use the top row numbers, not the numpad, which took me way too long to figure out because I kept hitting the wrong keys and getting wrong answers. And wrong answers mean nothing happens. She just sits there, fully clothed, judging your arithmetic.

There's a turtle somewhere in this game. I don't know why. Maybe it's a mascot or maybe it's just there to make you feel weird about jerking off to math. The strip mechanic is straightforward: solve enough problems, she loses a piece of clothing. Bra, panties, the usual progression. But the pacing is all wrong. You'll get three correct answers in a row and she'll take off her shirt, then you'll blank on 56 divided by 7 because you're distracted by the nipple that just appeared, and suddenly you're stuck on basic division like a middle schooler.

The VIP tag suggests there's more content locked somewhere, but honestly the base game feels like a fever dream someone coded in an afternoon. The art style is rough, deliberately unpolished, like a sketch that got colored in with whatever was lying around. Her proportions are absurd, the kind of body that would break a real spine, but that's the point I guess. It's not trying to be classy. It's math and tits and a turtle. If you can't do mental arithmetic while aroused, this game will humble you fast.

I got stuck on question seven for like twenty minutes. Not because it was hard, the math is baby stuff, but because the little hentai scene from question six kept replaying in my head. Mak's whole deal is he sees past and future, right? So the quiz is basically his fractured timeline, and every correct answer peels back another layer of some girl's clothing. Or adds a new position. The logic is... questionable. Why does knowing the square root of 144 mean she takes off her bra? Don't care. The visual novel bits between the math are this weird, horny collage of moments that haven't happened yet, or already did. There's a scene with a girl on a couch that feels like a memory Mak is stealing from himself. The art is that specific Hentai Bliss style, all soft lines and improbable anatomy, but it works because the whole thing feels like a fever dream anyway.

The quiz part is genuinely just arithmetic. Addition, subtraction, multiplication. The difficulty slider is a lie, it just changes how many questions before the next reward. I respect that honesty. You're not here for a brain teaser, you're here to see if answering 8x7 correctly unlocks a tittyfuck scene. It does. The story tries to be deep about fate and precognition but honestly Mak's power is just an excuse to string together disconnected erotic vignettes. There's this one girl with short hair who appears in what I think is a flashback, but the timeline is so jumbled I might have been looking at her future self. Or past self. The game doesn't clarify and I stopped caring around question fifteen when the teacher character started doing things that would get her fired in any timeline.

The interface is barebones. Click the right number, bar fills up, scene advances. Sometimes the wrong answer gives you a different scene, which is a nice touch. Makes failure feel less like punishment and more like a branching path into a different fantasy. The whole thing is maybe thirty minutes if you're good at basic math. Longer if you keep clicking wrong on purpose.
