I translated pieces of an article from 1963 and posted them below. You’ll read about how the animal game was played in Cambodia, how different variations of the game pre-existed the one we all know (including the more prominent flower game), and that Brazilians have a Mexican to thank for the continuation and proliferation of the game in Rio.

Despite a law to the contrary, the animal game is considered one of the most serious institutions in Brazil. And every afternoon, from one end of the country to the other, Brazilians ask themselves: “What animal did you get?” The animal game only exists in Brazil and in Phnom Penh, Cambodia. The animal game started to be played in Brazil and only a few years later it was introduced in Phnom Penh. Senator Érico Coelho (depicted), who in 1915 proposed to congress the legalization of the animal game throughout the country – which occurred for the first time – justified his bill with the fact that it was an eminently Brazilian game, warning that it would be easier pass a camel through the eye of a needle than to make people stop gambling on the camel.
Before the animal game appeared in Brazil, there existed, with the same characteristics, the game of flowers, fruits, birds and numbers. Before the advent of the animal game, the numbers game was very popular in Espírito Santo. The flower game, however, was the one that had the most fans throughout the whole country. As in the current animal game, the other games consisted of 25 numbers, a fact for which no one has yet found an explanation. […] A Mexican, by the name of Manoel Ismael Zevada, was the biggest financier of the flower game in Rio. His bank was on Rua do Ouvidor, according to the chroniclers of Old Rio.

This is where the Barão de Drummond comes into play. João Batista Viana Drummond, a friend of Dom Pedro II, from Minas Gerais, would address Princess Isabel as “my angel” and, in her honor, named the farm on his property after her. It would become Vila Isabel – on the former Fazenda do Macaco, where he founded a zoo (on the slope of the Serra do Engenho Novo), which was the first that Rio had. […] Because he was one of the monarchists who supported Marechal Deodoro da Fonseca, Barão de Drummond fell into disgrace with Marechal Floriano Peixoto, who cut the annual sum that the Federal Government gave for the maintenance of his Zoo by 10 contos de réis. That was in 1892.
The Mexican, Zevada, knowing that Barão de Drummond was going to close the Zoo, due to a lack of financing, proposed the animal game – just as he did on Rua do Ouvidor – in order to keep it going.
Quickly, the animal game dominated the city and the zoo was no longer big enough for the visitors, who went to Vila Isabel to gamble more than they went there to see the animals in the zoo.
In less than a year there wasn’t a corner in Rio without an animal game, which alarmed the police, who prohibited it at the zoo. Already rooted in the habits of the carioca, it began to be played out of sight…
