# 065 Hand Flop Game

This app turns the template into a wrist pronation/supination game for two vibrating sensor nodes. Haptic cueing is always on because it is fundamental to the task.

Mount one sensor on the inside of the wrist and one on the outside. At each cue interval, one node vibrates. The player should rotate so that the cued node ends the interval on top.

Scoring:

- Correct top node at the end of the interval: `+1` by default
- Repeat cue with unnecessary wrist rotation beyond the configured orientation swing threshold: `-1` additional penalty by default, even if the correct node still finishes on top
- Cue repeats and the player rotates away from the same target: `-1` by default
- Cue changes and the player misses: `0` by default, but this is configurable

The app uses accelerometer `Z` data to estimate which node is on top, matching the intended mounting where the `Z` axis runs through both nodes. For both wrist sensors, a positive normalized `Z` means that sensor is up. This version is vibration-only and does not use audio prompts.
