Addix (c64/v20/c16/zx/pc)

A game for the Commodore 64, Vic20, Plus4/C16, PET40/80, ZX Spectrum, DOS, and SDL2 (Windows and Linux).

Addix is a classic 2 player game, you against the computer.

You select a number from the current row, using SPACE then ENTER to move.

The number you select is added to your score.

The Computer replies by selecting a number from the column of your  last move. When a side no longer has a move left, the side with the highest score wins.

COMMANDS:

   SPACE : Select a move.

   ENTER : Make a move.

   N : Start a new game.

   G : Make Computer take your move, swapping sides.

   I : Set Computer search depth. (1-9)

   T : Toggle 2 player mode, Human vs Human.

   F : Toggle board frame off/on.

   H : Show Help screen.

   Z : Start a new game, with the same layout. (N for next layout)

   A : Autoplay, Computer vs Computer.

   W,E : Resize board, from 4x4 to 10x10.

   ESC  : Quit to OS.

The scores are shown at the top:

"H:XXX V:XXX" H=Horizontal player (normally Human), V=Vertical Player. 

You play normally takes the Horzontal row of numbers, with the computer replying taking from the vertical column of numbers. 

If you hit 'G' the computer takes your turn, and you swap sides,  with you taking the Vertical numbers.

The IQ search level is normally restricted to the range 1-9, wrapping back to 1 when you go past 9.

This is the number of moves to look ahead, so if you set IQ=1 the computer just selects the highest number in the column.
