Rules:
The Rabbit Game (based on the boardgame "Max Mümmelmann")

Introduction:
While having holidays in Germany I stumbled on the boardgame "Max Mümmelmann".
This game had all the potention to become my next 1K hires game.
I have made another 1K hires game now, alhtough not all rules are implemented in this 1K hires version.

The game:
After loading you will see a disrupted board.
Press A-G to start.

The board will clear and the first player throws a die.
The board is circular and the movement is (anti)clockwise. The pawn (smiley) will move the number of positions thrown with the die.
Select (anti)clockwise with 9 and 0. These keys also respond to do the movement of the computer, although the AI will determine the direction.

After reaching the target field 4 options are possible
1) the field is empty and no card is drawn
2) the field draws a card you already have, the smiley is shown
3) a new card is drawn, you see your new card on that field
4) you draw the carrotcard (it moves over the board after being found)
The computer will take a rabbit you don't have from a the computerplayer
If nobody has a rabbit you don't have you won't get anything

Each field on the board starts with 3 cards. When you get a card you already have it goes to the bottom of that stack.
The extra carrotcard always goes on top. The deck of cards have 4 complete rabbitfamilies. 4x6=24 cards, 24/8=3 cards per field.

The winner is that player who has found all 6 rabbits.

Name of Software: Space Rescue TS-1000
Author: Donkeysoft
Release Date: 27-02-2017
Requirements: 2K RAM
Description: An attempted conversion of a ZX80 1K game here: viewtopic.php?f=4&t=1218&start=10#p24282
When it was apparent that 900 bytes wasn't enough to make this game on the ZX81, I decided to use the unexpanded TS-1000 as a minimum spec. Find the stranded space ship in the dangerous and uncharted galaxy using keys 5, 6, 7 and 8; beware of Asteroids (though you don't always lose energy when they are encountered because of your ace navigation skills). Refuel at friendly planets when you find them. Based on Intergalactic Space Rescue for the Sinclair ZX Spectrum. Good luck.
Note: Dr Beep noticed a typo present on the screen shot. Corrected the typo and updated the download; screen shot with typo left as is.
