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.

Meliodas and Diane had finally arrived, their presence shaking the very foundations of the prison. But for Ban, this wasn’t just a rescue mission—it was a long-overdue reunion. As he casually strolled through the crumbling corridors, regenerating from wounds that would have killed a mortal ten times over, he finally locked eyes with his Captain.
"And you’re still a loudmouth, Ban," Meliodas retorted with a smirk.
"Captain," Ban grinned, his eyes gleaming with a manic sort of joy. "You look as puny as ever."
The reunion wasn't celebrated with hugs, but with a punch so powerful it leveled the rest of the dungeon. As the dust settled, the Seven Deadly Sins felt a brief moment of triumph, unaware that the Holy Knights were already moving their pieces across the board.
In the kingdom of Liones, the air in the was thick with the scent of ozone and damp stone. Inside, the battle between the Fox Sin of Greed, Ban , and the Weird Fangs was reaching its chaotic peak.
Elizabeth watched them, her heart racing. She saw the bond between these "monsters"—a loyalty that transcended the dark rumors whispered in the villages. They weren't just sins; they were a family. But as they began their trek toward the , a new shadow loomed. King, the Grizzly Sin of Sloth, was watching from the trees, his spear at the ready and his heart filled with a quiet, icy rage directed solely at Ban.
