Step inside The 21 Desires — an underground adult casino where the stakes go well beyond money.
Play Blackjack, earn your way up through increasingly exclusive tables, and build a collection of explicit animated cards. Every hand you win unlocks something new. Every hand you lose costs you more than you think.
Three worlds. Straight, Gay, Trans — each with its own tables, its own packs, and its own escalating content. The further you go, the more the house reveals.
The cards never lie. But they always tempt.
The Trans world is available now in early access on Patreon

Developer Notes:

This is my first released game — I’m a solo dev learning as I go. Be kind, and know that I have a lot planned. Feedback is more than welcome!
Future updates will expand the game significantly: more cards across all rarities, new gameplay mechanics, additional Straight tables — and the opening of the Gay and Trans branches, each with their own tables, packs, and exclusive card collections.
