HP Prime: At the Races


HP Prime:  At the Races

I am planning to do lots of gaming this month of June 2018.

Note: Symbols that are produced by Unicode should, but may not show up on all browsers. Please make sure your browsers are updated to the latest version.  

🐎 (Trumpet Sounds)  🐎

The program GAME_RACE simulates a race between seven racers:

Apple Ρ½  (Decimal Unicode: 1149, Hexadecimal Unicode: 47D)
Knight ♞ (Decimal Unicode: 9822, Hexadecimal Unicode: 265E)
Spade ♠ (Decimal Unicode: 9824, Hexadecimal Unicode: 2660)
Club ♣ (Decimal Unicode: 9827, Hexadecimal Unicode: 2663)
Heart ♥ (Decimal Unicode: 9289, Hexadecimal Unicode: 2665)
Diamond ♦ (Decimal Unicode: 9830, Hexadecimal Unicode: 2666)
Spike ✥ (Decimal Unicode: 10021, Hexadecimal Unicode: 2725)

To watch a race in action, all you have to do is to run GAME_RACE.  Betting not included.
