Now, let’s walk through each step so that you can complete the form without hesitation.

① Choose the Boat Race Venue

First, mark the number corresponding to the boat race venue at the top of the slip.
For example, Heiwajima is represented by number 4.

② Select the Race Number

Next, select the race number you want to bet on.
In most cases, venues host 12 races per day.

③ Choose the Bet Type

Then, choose the bet type by marking one of the following letters:
A = Exacta, B = Quinella, C = Quinella Place, D = Trifecta, E = Trio.
If you’re unfamiliar with each type, for example, Exacta and Trifecta, then refer to our detailed guide on Types of Bets in Boat Racing.

④ Mark the Boat Numbers

After that, fill in your predictions for the top positions.
Specifically, for a Trifecta bet, mark 1st, 2nd, and 3rd place.
Do note that boat numbers range from 1 to 6.

⑤ Enter the Bet Amount

Finally, mark the number of units you wish to bet, and then select the corresponding unit.
For example, to place a 300 yen bet, you would write “3” and select “百” (hundred yen).
Before submitting, always double-check the race number and your boat selections to avoid mistakes.
