Bicho room: rules of the 100-ball bingo with the 25 animals
The Bicho room is a 100-ball bingo (01 to 00) inspired by the traditional Brazilian table of 25 animals: each animal owns four consecutive numbers, every ball shows its animal and, besides line, two lines and full card, there is the Animal of the Round prize for players who picked the animal of the ball that completes the full card. All with virtual chips that have no monetary value.

The table of 25 animals
A ball’s animal is its number divided by 4, rounded up; ball 100 shows as “00” and is the last number of the Cow (Vaca).

| 3. Burro | 09–12 | 16. Leão | 61–64 |

The card
A Bicho room card is 5×5 without a free cell: 25 real numbers. Each column draws 5 numbers out of 20 (B 01–20, I 21–40, N 41–60, G 61–80, O 81–00), that is, from the numbers of exactly five animals. Without a free cell every animal has exactly the same chance, 1 in 25, of owning the ball that completes the full card.
How to play a round
- During the sale, buy 1 to 4 cards (50 virtual chips each).
- Pick your animal of the round for free; you can change it until the sale ends.
- Balls come out one by one; line, two lines and full card work as in 75-ball bingo.
- The ball that completes the first full card sets the Animal of the Round.
Pot split
| Prize | Of the pot |
|---|---|
| Line | 15% |
| Two lines | 20% |
| Full card | 45% |
| Animal of the Round | 10% |
| Accumulated pot (paid with the full card within ball 66) | the rest (≈10%) |
The Animal of the Round is split equally among the players who picked that animal — per player, not per card. If nobody picked it, that share goes to the accumulated pot. Because of this, a player with 1 card gets, on average, a bigger part of this prize per chip than a player with 4; the room as a whole still pays out 90% of sales.
Verification
As in the other rooms, the seed hash is published when the sale opens and the seed is revealed after the draw; the order of the 100 balls and your cards are recomputed in the browser. In a 1-million-round simulation the room returned 90.12% of sales, inside the expected interval.
