Ok, please look over the HP 41 Yahtzee game here
The .raw file linked to here is the current version of my 31 year on/off interest in a game for the HP 41 platform to play the dice game Yahtzee. The .raw file program is 636 bytes long.

Yahztee raw file

Wiki link for basic rules of the game here:

wiki link

The game includes the small straight routine posted here on the forum by Werner as part of the HHC 2015 programming contest. I modified it only to change register references and the labels used. Note: The sorting routine uses the RAD indicator in the display to indicate numbers are being exchanged/sorted. I find this rather cool to see it flashing on and off.

Basically to play:

XEQ YZ
Enter a decimal seed between 0 and 1.
Choose the position of the dice you wish to roll. If you see 23356 ROLL? displayed and want to keep the 3's and roll the 2, 5 and 6 again, key 145 R/S. You get two rolls and then have to score. To score, enter the number of the scorecard row you want to use and press R/S. If you cannot remember which ones are still open, press 0 at this point and press R/S.

By the way, if you get a good roll initially or before prompted for the SCORE? you can enter a 0 instead of the positions of the die and it will skip rolling any dice and immediately go to the SCORE prompt. Why would you want to do this? Suppose you get 22222 ROLL? on the first roll? That's a yahtzee and you should want to score it in row 12. To do that, press 0 R/S and you will see 22222 SCORE? Key 12 R/S and it will score in yahtzee if that row was previously unused. If you skip ahead to SCORE? but then realize you really want to go back and ROLL then you are stuck. No can do.

The scorecard is as follows:
1-6 - score the number of each 1, 2, ... 6 you received.
7 - 3 of a kind
8 - 4 of a kind
9 - full house (3 of a number and then 2 of some other number)
10 - small straight
11 - large straight
12 - yahtzee (5 of a kind)
13 - chance - total of all dice shown

If you get 63 or more points in the rows 1-6 of your scorecard you get a bonus of 35 extra points.

This game does not implement "bonus" yahtzees if you get more than one in a game.



Feel free to :

1) Find bugs :-)
2) Rationalize the labels used. Been a long time and other than labels 1-13 the labels used are not critical.
3) Suggest improvements
4) Add bonus yahtzee scoring
5) Play it and have fun. :-)

I'm hoping some of you can check it out before it gets committed to Angel to update the version used in the FUNSTUFF rom that goes into the HP 41CL. The program in there now has bugs in the LBL 10 small straight section.

Thanks and enjoy.

RE: Ok, please look over the HP 41 Yahtzee game here
Hello Gene,

Very nice RPN implementation of one of my favorite game when I was a kid.
I played three games on Genesis-41 OSX simulator and it worked flawlessly.

I have a small suggestion, since you made it for the 41, why not use the auto-assigned labels (A..J,a..e) for actions.
We could then create an overlay for your game!

Thank you for sharing. Smile

Best regards,

Sylvain

Here is my suggestion for the labels ...
Code:
Now  Label  Action
---  -----  --------------------------------------------------------------------
  1  LBL A  Save to 1 
  2  LBL B  Save to 2
  3  LBL C  Save to 3
  4  LBL D  Save to 4
  5  LBL E  Save to 5 
---  -----  --------------------------------------------------------------------
  6  LBL F  Save to 6
  7  LBL G  Save as 3 of a kind
  8  LBL H  Save as 4 of a kind
     LBL I  Show current saved values
     LBL J  Roll dices (identified in X)
---  -----  --------------------------------------------------------------------
  9  LBL a  Save as full house (3 of a number and then 2 of some other number)
 10  LBL b  Save as small straight
 11  LBL c  Save as large straight
 12  LBL d  Save as yahtzee (5 of a kind)
 13  LBL e  Save as chance - total of all dice shown
---  -----  --------------------------------------------------------------------

RE: Ok, please look over the HP 41 Yahtzee game here
Thanks Sylvain.

I'm particularly interested in:

The scoring routines - especially for cases that should fail. 11235 should not be a small straight - does it score as one? (Answer no, but there are lots of such cases)

and

Places where my routines are byte hungry. The Large Straight routine (LBL 11) for example - can it be done shorter? How?

FYI - Labels 01 through 13 score the corresponding row on the scorecard. LBL 07 is the 3 of a kind label.

Thanks all. Please play the game and help test it before it gets replaced in the FUNSTUFF rom.

Gene,
you haven't recognized my refined and very compact solution that I posted here three weeks after the conference. Based on that approach I offer a combined routine for the small and large straight, which is 39 lines long

Code:
LBL 10        Start for small straight
XEQ 35        do the evaluation for straight
30            possible score
7            to compare with hit-counter
GTO36        goto final evaluation for score
LBL 11        start for large straight
+            No idea what's that for GENE recheck
XEQ 35        do the evaluation for straight
40            possible score
6            to compare with hit-counter
LBL 36        final evaluation for score
RCL Z        get hit-counter
X>Y?        not enough hits? then..
RTN            .. fail
RCL Z        otherwise get score
STO 20        and store
RTN            finished with success
LBL 35        evaluate for straight
RCL 15        If die two is 2
RCL 17        and die four is 5
*            then there is a hole, and no small straight,
10            not relevant for large straight
X=Y?        but handy to have the 10 also available as hit-counter
RTN            .. failed
RCL 23        Get loop counter 14.018
ISG X        Add 1 for retrieval of next number
RCL 14        Get first number
ENTER^        create dumy number for later use
LBL 50        start loop
SIGN        turn previous dummy number into "1"
+            increase first number by one
RCL IND Y    get next number
X=Y?        if they are equal then we have a hit and
DSE T        decrease the hit-counter, it started with 10
X<>Y        save the last retrieved number to Y. X is dummy now
ISG Z        increase loop counter    
GTO 50        if something left to do
R^            lift stack to move hit-counter to X
RTN            go back to score evaluation

In your code you have "+" right after "LBL 11" . As I have no idea what that's for, I left it in, may be it can be deleted.

Hope you can use it,
Günter

Thank you Guenter! I must have missed it.

I will look it over and try it out. Thanks for making the adjustments to the registers, etc., used in the program.

RE: Ok, please look over the HP 41 Yahtzee game here
About that +

Perfect find. No idea why I had it in there. When the call to LBL 11 is made, the X register has a 0 in it and the program was recalling a value and adding it to that zero. No harm, but totally unnecessary. Oops. Probably got dropped in 25-30 years ago when I was in graduate school and never thought about again.

Nice! However I'd suggest you delete the "ENTER^" after the 2 "XEQ 35" statements. While it doesn't change the byte count, I think it's less clutter.

Funny. :-) I added the ENTER to make sure the code was more readable from the listing. I've seen times when lines without an enter were considered a mistake and the two numbers were joined!

RE: Ok, please look over the HP 41 Yahtzee game here
Some years ago, I modified the scoring table for Yahtzee (I had learned the game under the name of General; I think the game comes from Cuba.) If I can find them, I'll send you the new scoring rules. There are some bonuses that one can play for (at the risk of losing other scores, of course) and I found the game much more interesting.

Hi Gene,

Is there an annotated/commented listing floating about -- at least maybe explaining the purpose of the various sections/subroutines?

RE: Ok, please look over the HP 41 Yahtzee game here
Try this:

Code:
SIZE 024

Register usage:
00 – random number seed
01-13 – the values in each row of the scorecard
14-18 – the individual dice stored 1 per register
19 – the number of rolls made so far.
20 – the score for the current scorecard row
21 – used to store the scorecard row being evaluated
22 – holds the value 1-6 when scoring top of scorecard
23 – holds the 14.018 loop index

This is the initialization section. It clears registers, stores the random numbers seed in memory 00 and clears flags 0-20.

GTO 71

By putting 12345 into X and going to LBL 71, the program will roll all five dice. Since this is the first time, that will initialize registers 14-18 with a die in each register.

This section of code increments the roll counter and checks that it is roll 1 or 2. If so, then the player can roll some or none of the dice again. If the roll counter is 3, then it is time to score. Instead of this code, should I store 2 into register 19 when the first roll is made instead of zero and then replace this code DSE 19 GTO 22?

The GTO 61 simply skips ahead redisplays the digits but skips ahead to the SCORE? prompt by setting flag 0 here.

Label 71 takes the user input of which dice to roll and slices a digit at a time from the input, adds 13 to the digit and then rolls a new die for that register. Loops until the digit is a 0 (means it has rolled all digits)

A negative value (-7 for example) says to score in row 7 but that a second yahtzee is implied. The program checks if a previous yahtzee has already been scored and if so, scores the roll into the absolute value row indicated and adds a 100 point bonus to row 12. This is checked down in label 65.

GTO 63

At this point, two things are indicated. Flag 20 is set indicating a second yahtzee has been achieved but the bonus cannot be paid unless the roll also has a valid score on the row indicated. For example, a second yahztee of 11111 cannot be scored in row 10 small straight. True, you might have a second yahtzee but it has to go into a row where it scores a value.

So, the above code only goes to label 63 if X is equal to zero or if X is not equal to zero and flag 20 is set. That would indicate no second yahtzee so go to label 63.

Label 40 is the sorting routine. It sets degree mode (flag 43) upon entering. It compares adjacent registers and swaps them if out of order. When a swap is made, RAD mode and the RAD annunciator are set, which changes flag 43 status. At the end of a sweep through the registers, if RAD is set, a swap was made and the sort is not over.

I am ok shortening this LBL 40 routine with another sort, but I do find it kind of fun to see the RAD go on and off.

Regarding this section of code and converting it to a DSE 19 approach...

Code:
LBL 17
1
ST+ 19
RCL 19
3
X<=Y?
GTO 22

I have found that it raises my byte count by 4 bytes with changes that have to be made elsewhere. So, I think I will leave it as-is.

I am also changing line 134 which is presently an append blank space to an append + instead.

Angel, the .raw file will be sent by tomorrow if at all possible.
