Before you begin, you'll need to configure the following two items: ・Mode  To accommodate those who don’t like tapping repeatedly, the app offers three modes:  1. Normal Mode: Tap once to pull the gacha once. You can also long-press to pull repeatedly.  2. Fast Mode: Long-press to pull gacha continuously at high speed.  3. Instant Mode: Tap once to immediately pull until you hit a win. ・Probability Value  Tap the settings button on the main screen to go to the settings page, then select your desired probability from the dropdown list.  After selecting, press the “register” button at the top right to complete the setup. There are 11 preset probability values by default, but if the one you want to test isn’t listed, you can create your own on the settings screen. Enter a title name and the desired probability value, then tap the “Add to Title List” button. Your custom value will then appear in the dropdown list for selection. If you no longer need a custom title, you can also delete it by selecting it from the dropdown and tapping the delete button. Set your own preferred probability and try your luck today!
