Hentai Diaries is an erotic hentai adult game featuring a free-roaming environment, rotating and updating cast and richly animated adult sex scenes.

Characters with interactive scenes require a small amount of in game money, however Riley's tutorial free. In game money can be found at respawn points in-game which respawns roughly once a week.

Hentai Diaries was build by a small team of developers. We have put our heads together on the development for many hours but we don't consider our game perfect. Help us improve Hentai Diaries by writing a review, but do keep in mind that we have costs to cover to keep the game online and get new content added. We read and take any and all suggestions into consideration.

This funny video game appeals to those who like to solve math problems in their heads and see corrupt pictures of busty hentai girls. So look at the game screen. You can see beautiful pictures against the background of a girl with big breasts. After a few seconds, the formula will appear on screen. You have to solve it in your head and give the correct answer. For instance 5 + 8 =? Enter the answer using the keyboard. Each correct answer will change to a different level, and the game picture will change. You have limited time to answer, so hurry up. So if you're ready to start enjoying the perverted girl, do it now.

Oh god, another one of these. The quiz format that was stale in 2006 and somehow keeps washing up on the shore of adult gaming like a condom on a beach. You click through questions about what you'd do at a summer party or whatever, and then it tells you you're a "wild tiger" or some bullshit. The art is exactly what you'd expect from the "adult flash game" tag, girls with balloon tits that defy physics and anatomy, faces that look like they were traced from a hentai coloring book and then someone said "yeah that's good enough."

But here's the thing. I kept clicking. Not because it's hot, it's really not, the eroticism is about as subtle as a brick through a window. But there's something almost hypnotic about how unpolished it is. The broken English in the questions makes you squint at the screen trying to parse what the hell "do you like when touch the body on beach" actually means. Is it a translation error or some kind of avant garde poetry? I don't know and I don't think the developer knows either.

The "big boobs" tag is doing a lot of heavy lifting here because that's basically the entire visual experience. Every character has them, they don't move naturally, they're just sort of there like flotation devices attached to a torso. And the "pretty girls" tag is generous, they look like someone's first attempt at drawing anime after watching one episode of High School DxD. But I laughed. Multiple times. Not at the jokes, the game doesn't really have jokes, but at the sheer audacity of presenting this as a personality test. Like imagine taking a Buzzfeed quiz but the result is just "you want to fuck" and also the quiz was made by someone who learned English exclusively through porn titles. That's the energy. The humor isn't intentional but it's there, and honestly that's more than I can say for most polished adult games that take themselves way too seriously.

Right, so you walk into this shop to buy some DVDs, classic setup. But your wallet's empty, typical. The shop assistant though, he's got this look, you know the one. Like he's about to offer you something that's not exactly on the menu. Instead of kicking you out, he's like let's play a game. A shell game. Three cups, one ball, and if you can follow it with your eyes while he shuffles, you get the goods. Simple, right? Except the goods aren't just some random action flicks.

The first time I won, I didn't even process what was happening. The screen just... changed. Suddenly there's this girl, and she's not exactly dressed for retail work. The whole thing feels like finding a scrambled channel late at night back in the day, that thrill of seeing something you shouldn't. The art's got that slightly rough, unpolished vibe, like someone drew it in a hurry after everyone else went to sleep. It's not trying to be a masterpiece, and honestly that makes it hotter somehow. The girls are pretty in that very specific way, all curves and pouty lips, and they're doing things that would get you arrested in a real DVD shop. Blowjobs, stripping, the whole deal. It's all very... direct. No plot about saving a kingdom or whatever, just you, a lucky guess, and a girl who's suddenly very grateful you picked the right cup.

The shuffling mechanic is actually kind of addictive though. I kept losing on purpose just to try again, which is stupid because you're literally just watching cups move. But my brain would just... drift off mid shuffle. Like I'd be staring at the right cup, absolutely sure, and then the assistant's hands would do this little flourish and suddenly I'm second guessing everything. Is it the left one? No wait, it moved twice. Or was it three times? And then you click and it's wrong and you feel like an idiot. But when you win, oh boy. The scenes are short, looping animations basically, but they get the job done. There's this one girl with the dark hair who does this thing with her tongue that made me forget what I was even doing. The whole thing is just pure, uncut, degenerate fun. No pretensions. It knows exactly what it is and doesn't apologize. And the fact that it's all wrapped in this seedy little gambling premise just adds to the whole forbidden vibe. Like you're getting away with something.
