AWARI 1.1
For the HP48sx
By Garth Sweet
Copyright Jan. 1993
AWARI is a game based on the ancient African game of the same
name, it was originally played on a wood or stone board made with 14
holes or 'buckets' in it. In 12 of the buckets were placed 36 stones (3
per bucket), the idea of the game was to move stones from the 12 filled
buckets to your home bucket (one of the 2 empty ones).
AWARI for the HP48 replaces the wooden board and 36 stones with
the LCD screen, the board is drawn out onscreen as it wouldv'e appeared
in wood. Below is a simple ASCII representation of the board, to try and
show how the board is laid out.

The game requires two players, (although the HP48 can play one of them)
and each player gets one row of buckets plus an end bucket as thier own.
Player 1 gets the top row plus the leftmost bucket, player 2 gets the
bottom row plus the rightmost bucket.
To play, a player selects a bucket (by pressing a key A-F) and
the computer will take all the stones from that bucket, and place one
in the bucket next to it, then one in the next, and so on until there
are no more stones to drop (play moves counterclockwise). Each bucket
originally starts out with 3 stones in it, and the home's have none.
If for instance then player 1's 1st move was to move the stones from
bucket B (which would contain 3 stones). Then after selecting B, the HP
will add 1 stone to A (making 4 in A), 1 stone to home (making 1 in
home) and add wrap around and add one to player 2's A bucket (making 4
in player 2's A bucket). The idea is to get as many stones into your
home bucket this way as possible, the game ends when any player can't
play (thier side is out of stones) or any buckets has more then 18
stones (at that point someone has more then half the available stones so
they are guaranteed the win). But there are also a couple of other rules
to add a twist to the game, the 1st is that when a player is taking a
turn, if they make a move that results in the last stone being dropped
into thier own home, they get to go again (but only once per turn). The
2nd rule is that if the last stone being dropped is going into an empty
bucket, and there are stones in the bucket immediately across from it,
then the one stone plus all the stones in the bucket across go to your
home. The rules are simple really, just play once or twice and you'll
have the idea.
AWARI comes in the form of a library, to set it up, do the
following:
1. Download the library to the home directory of the HP48
2. RCL the library to the stack ( 'AWARI' [RCL] )
3. Type ':0:1160 [STO]'
4. Purge the AWARI library from the VAR menu ( 'AWARI' [PURGE] )
5. Turn the HP off and then on.
When you go to the library menu, there should be an AWARI directory
there, go to that directory and select AWARI.
AWARI takes up about 6K of memory, and is written in User RPL,
this makes it a little slow, perhaps, but not really, it's quite fast.
There are also two utilties that the library uses, and make be useful
to you aswell, they are GETS and PUTS, they work EXACTLY like GETI and
PUTI only they don't increment the counter, this means that after a PUT
you still have the counter on that stack of where you did the PUT at.
The two utilties will be useable in any program you write, so long as
the library is attached. Enjoy!
CHANGES TO 1.1:
- Pressing the BACKSPACE key will switch AWARI into an 'auto finish'
mode, the HP48 will automatically make the best (most point gaining)
move for each player. This makes it nice for when you can tell who's
going to win and don't want to go through the motions.
- Pressing ATTN to exit cleans up the stack completly.
- On ending AWARI leaves you in the LIB menu, not the VAR menu.
- Fixed virtually un-noticed key bug.
- Made game board symetrical. (Oops!)
Notes: This is the 1st library I've released, and while it works well
on my HP, I can't guarantee it at all for anyone else's. In
particular, I don't know if the library ID I picked is already
used by another program in circulation. If anyone has any
problems I would certainly be glad to hear of them, I'd like to
make sure the program is fully bug-free. This software is
released as use at your own risk. This program is released into
the Public Domain and is free to use and copy.
