Retro Horse Derby Game Board with Neopixels showing Reaction Game Status

Runtime detail that goes together with the clip in first post (see still of it attached below):

The dump of the board lane by lane into the console, before player 0 (yellow) wins the 3rd race and wins the game, from the boards perspective (<-- comments added). It shows the neopixel buffer as sent out - 30 bytes - byte by byte (3 bytes per line defining the R G B components for the LEDs). The bytes are sent in reverse order: the last bytes - bytes for the last LED in the string - are sent first, and the first bytes - bytes for the first LED - are sent last. Last 3 bytes - as sent first - are passed thru all but last LED from one LED to the next one. First 3 bytes - as sent last - are never passed on, they stay within first LED.

This is the matching players (variable) information (with some additional formatting):

>players
=[
  { idx: 0, racePos: 3, winCnt: 2, negPoints: 0,
    rClrs: [ 174, 81, 0 ],
    gClrs: [   8,  4, 0 ]
   },
  { idx: 1, racePos: 2, winCnt: 2, negPoints: 0,
    rClrs: [ 237, 0, 15 ],
    gClrs: [  11, 0,  1 ]
   }
 ]

Property negPoints not used (yet). Can be used to collect sub-par information relative to the winners in order to have more granular ranking across the races for a game or even beyond to indicate "better or worse losses / fare from or close to winning"...
