(50G) RPSSL (Rock Paper Scissors Spock Lizard)
Everybody knows the ancient game of "Rock, Paper, Scissors" which even has its own Wikipedia page. Almost as well known is the much newer 5-weapon version called "Rock Paper Scissors Spock Lizard" (aka RPSSL), invented by Sam Kass and Karen Bryla. The simple rules are on its official website.

Here's a surprisingly short HP 50g program that plays RPSSL, user against calculator, complete with the official winning messages!

Note: "SCISSORS DECAPITATE LIZARD" has been changed to "SCISSORS STAB LIZARD" to fit the display.

INSTRUCTIONS:
(1) Run RPSSL. See "PICK ONE!" at the top of the screen. The soft menu keys are now labeled ROCK, PAPER, SCISSORS, SPOCK, LIZARD, and EXIT.
(2) Choose a weapon by pressing it. The calculator immediately chooses its weapon (without looking at yours!) and displays the result of the match, e.g. "YOU: SPOCK. ME: LIZARD. LIZARD POISONS SPOCK. I WIN!"
(3) Repeat step 2 until you are sufficiently entertained.
(4) Press the EXIT soft menu key to exit and return the menu to its previous contents.

Code:
%%HP: T(3)A(R)F(.);
\<< { "ROCK" "PAPER" "SCISSORS" "SPOCK" "LIZARD" } DUP "EXIT" + TMENU CLLCD "PICK ONE!" 1 DISP
WHILE -1 WAIT 10.1 - DUP 5 \<=

  ROT GET SWAP GET " " + SWAP + " " SWAP + + 4 DISP "YOU" "I" IFTE " WIN!" + } IFTE 6 DISP
END DROP2 0 TMENU \>>
