The arena
People were slowly gathering when I entered. Everyone was dressed in a sarong to respect the spiritual aspect of the event. The sweet and sour smell of different food stalls let everyone know that the fights would start any moment now. Due to the amounts of money being gambled the food is said to be better here than on any other venue outside. Some people come here only to eat and for entertainment.
In the great circle arena a set of chairs was available for players, leaving the concrete stairs solely for the spectators. A dozen bamboo cages occupied the inside of the ring with new ones arriving in regular intervals. A cage inside the ring was an indicator of placing ones rooster up for a fight.
Awaiting the first gong, people played a local game of kocokan in between foodstalls, where one can bet on a field or two, and the dice would tell you if you were lucky or not. The starting rate was 10k IDR (~0.65 USD), yet only some bet that low. Apart from kocokan, people also entertained themselves with blok kiyu (card domino game) and capdeki (card ceki game).
Cock fights happen before important ceremonies and are held near the temples in order to entertain the spirits and prevent community animals from suffering from outbreaks of disease causing death. They say an entertained spirit is easier to become a positive one.
I'm not rich because I'm gambling
"Cockfighting is a very old tradition in Balinese Hinduism, the Batur Bang Inscriptions I (from the year 933) and the Batuan Inscription (dated 944 on the Balinese Caka calendar) disclose that the tabuh rah ritual has existed for centuries" - Wikipedia
Although the law protects cockfights' spiritual aspect, gambling has been illegal since 1981. That is why fights are not advertised. The place and time of the events are shared personally by word of mouth or WhatsApp. The arenas are well hidden from the main roads. People do not take videos or photographs during the events so they don't go viral, resulting in the attention of the police.
Nobody took their mobile phone out on the two arenas where I was present. When somebody would want to find the place where the fights are happening they would do that through the sounds and amount of parked motorbikes. That said, many people turn a blind eye to the events so long as they are within the confines of the arena.
As gambling is involved, local women wrote a song to men whose premise is: "I'm not rich because I'm gambling," expressing what is so common - people betting their last dime on the fights and leaving their families without enough to survive. It is a purely male sport in which women don't participate often. They are not banned per se, but, as one of my sources from Bali said, they: "have other, more feminine, work to take care of".
On the other hand, in Toraya regency (Sulawesi), it is not uncommon for a woman to bet yet it's uncommon to participate in a fight with her animal. My observation is that, although women seem to have have equal rights in Indonesia, they are socially pressured to attend to certain life activities rather than others. In practice, this leaves them in imbalance. Atop of this come various cultural and religious aspects in different parts of the country.
To respect being let in and getting permission to take photographs, I do not share the exact date or place where the events happened and publish this material after a while.
Gede's bet
People treat roosters as pets in Indonesia. Cocks who fight are also well taken care of and trained. The latter could mean being placed in a bamboo basket next to the road - to get accustomed to the noise while, at the same time, not getting into random fights with cocks of adjacent neighbours. The training is often held in home backyards at the same time ensuring the fights aren't lethal. After some time, the rooster gets accustomed to being calm before the fight and when held by a human.
All affluent players have assistants to take care of their livestock. They also have families who breed roosters for them and prepare them for fights. For a rooster, a single fight can be their last one.
The sought for animals have specific traits like no black freckles on their legs (brings bad luck) or camah (red splotches on their muscles, skin or tongues). A properly looking and coached rooster can cost from 10 million IDR (~650 USD) to 40+ million (~2500+ USD). This I learned from Gede who I met on the second, smaller, arena. His rooster also participated in the fights. You can guess whether a participant is wealthy by how they bring the animal: Is it brought in a bag or a colourful bamboo basket? Who carries the animal, the assistants or the owner? Where do they sit and how do they bet?
