## What is HitOne3?

This is a buzzer quiz judging machine that wirelessly connects multiple iPhones, iPads, and Macs.

Participants are divided into questioner and answerer, and each enters on their own device.
- There can be only one questioner.
- There can be a maximum of 10 answerers.

Please turn on Bluetooth and Wi-Fi.
You do not need to actually be connected to Wi-Fi as long as your device's settings are turned on. 

How to use

→ The questioner screen will be displayed.

2. All other people tap "Answerer"

3. The questioner asks the question

4. Answerers tap ○ quickly
→ The order in which they pressed is displayed.

5. The questioner taps "Reset"
