Game: Higher or Lower

[Chris-E-J-Ellis]

A take at an implementation of the "Higher or Lower" or "Play Your Cards Right" game. I've tested it on the emulator, and currently have it running on my Sensor Watch; I'm not entirely convinced it's fun, but it seems to be working as intended =D

Dumping description from the header file below:

Higher-Lower game face

======================

A game face based on the "higher-lower" card game where the objective is to correctly guess if the next card will
be higher or lower than the last revealed cards.

Game Flow

• When the face is selected, the "Hi-Lo" "Title" screen will be displayed, and the status indicator will display "GA" for game
• Pressing ALARM or LIGHT will start the game and proceed to the "Guessing" screen
  • The first card will be revealed and the player must now make a guess
  • A player can guess Higher by pressing the LIGHT button, and Lower by pressing the ALARM button
  • The status indicator will show the result of the guess: HI (Higher), LO (Lower), or == (Equal)
  • There are five guesses to make on each game screen, once the end of the screen is reached, a new screen
    will be started, with the last revealed card carried over
  • The number of completed screens is displayed in the top right (see Scoring)
• If the player has guessed correctly, the score is updated and play continues (see Scoring)
• If the player has guessed incorrectly, the status will change to GO (Game Over)
  • The current card will be revealed
  • Pressing ALARM or LIGHT will transition to the "Score" screen
• If the game is won, the status indicator will display "WI" and the "Win" screen will be displayed
  • Pressing ALARM or LIGHT will transition to the "Score" screen
• The status indicator will change to "SC" when the final score is displayed
  • The number of completed game screens will be displayed on using the first two digits
  • The number of correct guesses will be displayed using the final three digits
  • E.g. "13: 063" represents 13 completed screens, with 63 correct guesses
• Pressing ALARM or LIGHT while on the "Score" screen will transition to back to the "Title" screen

Scoring

• If the player guesses correctly (HI/LO) a point is gained
• If the player guesses incorrectly the game ends
  • Unless the revealed card is equal (==) to the last card, in which case play continues, but no point is gained
• If the player completes 40 screens full of cards, the game ends and a win screen is displayed

Misc

The face tries to remain true to the spirit of using "cards"; to cope with the display limitations I've arrived at
the following mapping of card values to screen display, but am open to better suggestions:

| Cards   |                          |
|---------|--------------------------|
| Value   |2|3|4|5|6|7|8|9|10|J|Q|K|A|
| Display |2|3|4|5|6|7|8|9| 0|-|=|≡|H|

The following may more legible choice:

| Cards   |                          |
|---------|--------------------------|
| Value   |2|3|4|5|6|7|8|9|10|J|Q|K|A|
| Display |0|1|2|3|4|5|6|7|8 |9|-|=|≡|

Future Ideas

• Add sounds
• Save/Display high score
• Add a "Win" animation
• Consider using lap indicator for larger score limit

Played with it a bit this morning — this is fun! Holding off on merging tho because I do think that your alternate choice might indeed be more legible. As it stands it is a little bit confusing that the value 0 is higher than 2 and I think that might throw people for a loop — but the use of graphical elements for the "face" cards of Q, K and A does indeed feel pretty intuitive to me.

Open to your feedback, happy to merge whenever you respond one way or the other!

Thanks for taking a look, and also for creating such a great platform! The alternative card faces only really occurred to me as I was writing up the instructions, and I think you're probably right they seem to require a touch less brainpower to figure out. Appreciate the second opinion!

I'll update the code either later today or tomorrow and re-merge in main, thanks!

Why the difference?

[Chris-E-J-Ellis]

I largely cribbed what some other faces did, but my understanding that is the emulator doesn't support the arc4random function, which I believe is a less predictable RNG.

This PR has been merged into main but did not automatically close because it was rebased.
