This game runs in Amstrad CPC 464, 664 and 6128.  
Programmed in Locomotive BASIC.  
Graphics, design and programming by Adam Ioannides.

## Source

Downloadable source code, CDT and DSK in Bitbucket: [Bitbucket](https://bitbucket.org/adamioan/amstrad-programming/src/master/Plain%20Basic/SudokuCPC/Dsk%20develop/)

## Disk contents

For adding, editing and change properties of files I used ManageDsk utility ( [ManageDsk - CPCWiki](https://www.cpcwiki.eu/index.php/ManageDsk) ).  
There are two disks in the project. One is the release (only mandatory files included, all files are hidden except SUDOKU.BAS, no break functionality) and the other is the development which contains:  
LOADER.SCR - Splash screen graphics in mode 0.  
GAME.SCR - Menu screen graphics in mode 1.  
SUDOKU.BAS - Main program written in single BAS file.

## Graphics

Graphics are created using Photopea.  
Screen graphics are compiled to CPC format using ConvImgCPC.
