This is a DOS game, which you can try to play in the browser through this platform or through GitHub. Follow the instructions below to run the game in a DOS machine.

---

Copy the files TILERS.EXE and CWSDPMI.EXE in the zip file to your DOS machine or emulator. The absolute minimum requirements are an i486 CPU and a VGA display.

TILERS

The base game is less than 360 KB, so it fits in a 5¼-inch floppy disk. You can download and extract the expansion pack for more levels. The expanded version is more than 360 KBs, but would fit in a 3½-inch floppy disk.

Launch options

To run the game without PC speaker sound, append nosound to the command line arguments:

TILERS nosound 

To change the initial disposition of the tiles, append an integer to the command line arguments to serve as the seed for the random number generator. The same number will result in the same puzzle arrangements.

TILERS 123456

These are all the options that you need to know.

Modding the game

You can add your own pictures too! If you add PNG files with the name #.PNG (where # is the level number starting with 1) next to TILERS.EXE, they will be picked up automatically and used as the picture for that level. For instance, if your directory structure is like this:

dir
.                <DIR>
..               <DIR>
1         PNG
CWSDPMI   EXE
TILERS    EXE 

Then the first level will use the image file in 1.png instead of the default picture for level 1 (the Monet painting La plage à Pourville, soleil couchant).

Moreover, you can do this to extend the number of levels available! Add 4.png to unlock level 4, 5.png for a fifth level, and so on.

Note however, that there are restrictions in place for the image:

• It must be a valid PNG image file in 8-bit indexed color mode
• It must have the exact resolution of 320x200
• It should not have more than 240 colors in total (the last few colors are reserved to the application and may affect presentation if this is ignored)
• And of course, not all pictures are visually appropriate for this kind of puzzle. The program will not check for identical tiles, so make it visually appealing as well as feasible to play!

You can use tools such as ImageMagick to adapt your image:

magick in.png -resize 320x200 +dither -colors 240 PNG8:4.png 

The command above works best when the input image is 4:3 in aspect ratio.
