Onyx is a computer sex game. Move around the board buying up properties. If you land on a property that is owned by somebody else, you must either pay rent or work off the debt! Players work off debt with all kinds of intimate actions, from mild to kinky. As the game progresses, so does the action! Play with people you are intimate with, or want to be!
You can work off the debt by being assigned fun, sexy erotic actions.
Look out for special squares! If you land on the Torture Chamber, you must draw a "torture card" with an erotic torture on it. At Center Stage, you are put on display; in the Random Encounter square, you will be assigned an erotic action with another player; and on the Fate squares, the luck of the draw dictates your fate.
You control the "spice" of the erotic actions, from harmless fun to wild, anything-goes kink. You choose "roles," which tell the game what kinds of actions you prefer to be involved in. If you don't like being tied up, just tell Onyx that you will not accept the "bondage" role.

Onyx 3.6 and earlier did not work on Macs requiring 64-bit native apps. Onyx 3.7 now works on modern Macs, and is optimized to run natively on Apple Silicon Macs. A version of Onyx that runs natively on Windows ARM devices is also available!
UPDATE: Some Mac users were reporting an error saying “Onyx 3.7.app can’t be opened because Apple cannot check it for malicious software.” I have updated the app to address this issue; it should work properly now.
Onyx runs on Macs (OS X 10.14 or later), Windows (Windows 7 or later), Windows for ARM (Windows 11 or later), and x86 Linux (GTK 2.0+).
Onyx is available for free download. The free version can only be played on the mildest two "spice level" settings. Onyx can be registered by paying the $35 shareware fee. Registration gives you a serial number to unlock the full version, and it also gives you the Card Editor program, which you can use to create your own card decks.
Onyx contains explicit descriptions of sexual acts. Some of the high-level actions in Onyx describe erotic actions like bondage and power exchange.

Picture this: a cramped, lantern-lit izakaya with lacquered counters and the warm tang of soy and grilled fish in the air. The regulars are a low murmur; the walls are plastered with handwritten menus and neon stickers. Into that cozy chaos burst our troupe—call them silly, call them fearless—each one a walking exclamation mark. They move like they’ve left a glitter trail, wielding chopsticks like scepters, issuing dares in half-whispered, high-spirited tones. The "v120" in the title feels like a badge of honor, a vintage firmware update for mischief: polished, perfected, and altogether unapologetic.
Visually, the piece reads like a manga panel exploded across an izakaya floorplan—exaggerated expressions, dramatic poses, and a soundtrack that swings from cheesy pop to the clink of ceramic cups. Yet there’s also a warm human pulse beneath the stylized antics: late-night confessions over spilled sake, a quiet encouragement passed between friends, the soft reveal of vulnerabilities under neon light. These moments give the silliness teeth; they root it in real affection. silly girls quest v120 izakaya yottyann exclusive
In short, "Silly Girls Quest v120 Izakaya Yottyann Exclusive" is a celebration of playful rebellion: a compact, effervescent universe where the rules are rewritten in lipstick and laughter, and where the greatest treasure is the perfectly timed, communal burst of amusement. It’s less a polished spectacle and more a living, breathing campfire of mischief—messy, memorable, and utterly contagious. Picture this: a cramped, lantern-lit izakaya with lacquered
What keeps the scene sparkling is the balance between chaos and camaraderie. The mischief never tips into cruelty; it’s carefully choreographed nonsense where everyone’s in on the joke. Even the riskier stunts—teetering stacks of plates, a dare to sing a ridiculous ballad—are cushioned by shared laughter and quick hands. The stakes are personal but tender: the mission isn’t to shock so much as to knit people together tighter through the shared absurdity of it all. They move like they’ve left a glitter trail,
"Silly Girls Quest v120 Izakaya Yottyann Exclusive"—what a title: equal parts wink and mystery, like a neon sign buzzing above a narrow alley you only find after three wrong turns. From the moment the name hits your ears, you know you’re in for something mischievous and unabashedly joyful, a little backstage romp where giggles are currency and rules are optional.
At the center is Yottyann—equal parts ringmaster and rogue—whose laugh ricochets off the sake barrels. She has that magnetic pull where even the stoic bartender finds an errant grin slicing through his concentration. Her exclusivity isn’t about velvet ropes; it’s about invitation-only energy: an atmosphere that says, "Bring your quirks, abandon your scripts." Around her, the silly girls execute mini-quests with gleeful precision—stealing a sliver of the chef’s prized katsudon, orchestrating an impromptu toast with oddly matched glasses, or turning a mundane receipt into a treasure map. Each caper is small-scale theater, an affectionate nudge at the ordinary.
As for the "exclusive" tag—don’t be fooled. It’s an exclusivity born of ritual rather than gatekeeping. You don’t get in by credentials; you get in by letting go, by matching the tempo of the room and surrendering to delight. That makes the whole affair feel like a secret handshake shared among conspirators of joy.
I have temporarily turned my attention away from Onyx 4. Late last year, my mother was diagnosed with cancer, and this has distracted me from Onyx 4.
I am pleased to announce that I have refactored Onyx 3 to work with modern versions of macOS and run nativeon Apple Silicon. Onyx 3.7 is now available, and works with Intel and Apple Silicon Macs.
The Card Editor 3.6.7 is now available for modern Macs. This version of the Card Editor works natively on Apple Silicon as well.
