I don't know jack about tarot but I came across an animalistic deck of tarot and decided to go ahead and order it, just for the art work, anyone into tarot around here....Is it a game???
The really short answer to your question is yes...and no.
Most people think the 52-card deck developed from the 78-card tarot deck, but in reality, it was the other way around. Tarot originated as a card game, where the "Major Arcana" were simply a trump suit in a trick-taking game. You can still find the game version of tarot - I think it originated in France and is still played there and in some other countries, Italy in particular. The "Minor Arcana" had simple French suit pips on them, not interpretive artwork. But over time, that deck did develop (as did the International Standard/French deck) to be used for
cartomancy, or making predictions of people's lives and future events through the use of cards. Some artists started making versions of both tarot and French/standard/52-card decks for fortune telling - some were simple, like the Gypsy Witch deck, having images of the original card design and additional art and text explaining how to use it in fortune telling, while the more complex ones had unique art for every card, incorporating the card's rank and suit into the artwork in some fashion. Arguably the most well-known version of that would be the Rider-Waite tarot deck - I'm sure a quick Wikipedia search of the term will produce lots of information about its origins. That particular deck's design must be in the ballpark of a century old by now; many printers have reprinted it and it's no longer protected under copyright, to the best of my knowledge.
If you poke around, while most of the decks and designers around here work in the International Standard, you'll find a healthy contingent who are also making tarot decks. Two noteworthy ones were previously mentioned - Uusi is a husband-and-wife team that used to be Chicago-based but now resides in the upper peninsula of Michigan, while Stockholm17/Lorenzo Gaggiotti is an extremely popular Italian artist who resides in Stockholm and uses it as his base of operations. I've actually worked with both - I did consulting work for Uusi early in their card-designing tenure and I produced stripper decks for a Stockholm17-designed deck made for a Swedish magician. Lorenzo was a double-winner at the 52 Plus Joker 2019 Diamond Awards, taking home both Artist and Deck of the Year, while Uusi won the 2017 Diamond Award for Artist of the Year.
