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.

Henry realized that some treasures are not meant to be possessed, but to be protected and shared with the world as part of a shared history. He took out his camera and notebook, ready to document the find of a lifetime.
As Henry traced the winding paths drawn on the parchment, a sense of adventure took hold. He had spent years studying local legends, but this map pointed toward a region long thought to be inaccessible. Driven by curiosity, he packed his gear and set out for the rugged cliffs of Cape Vedra.
The trek through the dense jungle was challenging. Every rustle in the undergrowth and every distant birdcall added to the atmosphere of mystery. Henry found himself solving environmental puzzles—aligning stone pillars to catch the midday sun and deciphering carvings on ancient ruins—that seemed designed to test the wit of any seeker.
The discovery of an old, leather-bound journal in a dusty attic was the beginning of an unexpected journey for Henry. Tucked between the yellowed pages was a map titled "The Secret of the Verdant Coast." It didn't look like a typical historical document; the ink seemed to shimmer with a faint, metallic luster under the light.
Deep within a hidden cavern, he finally stood before a massive stone door adorned with the same shimmering symbols from the map. As he placed his hand on the cold surface, the door groaned open, revealing a chamber filled with artifacts from a forgotten civilization. It wasn't just gold and jewels that lay within; it was a wealth of knowledge preserved for centuries.
