Light | Performance-oriented | |
Basic | Balance-oriented | |
Pro | Accuracy oriented |
About AI Model Operation Test
You can perform a test to determine which AI model is suitable for your device. Test results are displayed in three levels

Evaluation | Contents | Scoring processing time (approximate) |
---|---|---|
Operable | Comfortable to play | Less than 1.5 seconds |
Delay | Slight delay in judging speed, but playable | 1.5 to 3 seconds |
Inoperable | Not usable due to significant delay in judgment speed | More than 3 seconds |
In this test, only “terminal processing power” is checked.
Actual play may take slightly longer than the test results due to the additional processing of receiving images from the camera.
If your network speed is extremely slow or unstable, your score judgment may be delayed significantly. We recommend that you use a stable network environment in order to play the game comfortably.
3. Is the camera in focus?
The camera’s focus can be adjusted by rotating the camera’s focus ring. If the focus is out of focus, darts will not be recognized correctly.
Please check the camera image to ensure that the image is clear, as the focus may be shifted when the lens cap is removed.
