Descartes Rainbow is the sequel to Descartes Enigma. It’s the same basic game idea, except that Descartes Rainbow (naturally enough) supports multi-colored puzzles. Puzzles are constructed with any of 12 different colors (black, gray, white, brown, red, orange, yellow, green, cyan, blue, purple, and magenta). Most puzzles have between 3 and 7 colors in them. The clues, of course, show you the color of each block on a row or column as well as the number of squares in the block. In Descartes Enigma, you knew that there was at least one white (background) square between any two black (colored) blocks. In Descartes Rainbow, the background color is not necessarily always white (although that’s most common), and there may or may not be any background colored squares between two adjacent colored blocks (unless those two blocks are the same color, then there has to be at least one background square between them, to keep them from being the same block).

In Descartes Enigma, all deductions involved just looking at the clues for a single row or column. In Descartes Rainbow, you can frequently (and sometimes have to) make deductions by comparing clues in both the rows and the columns at the same time. For example, if a row has a clue that is RED 4, you know that it can only be located in 4 adjacent columns that have RED clues. That can frequently narrow down the possibilities dramatically, but can also add a more complex puzzle-solving experience. This makes the game very similar to Descartes Enigma, while at the same time giving it a unique twist.

Descartes Rainbow comes with over 1250 multi-colored picture puzzles, and over 6,000 random multi-colored “ink-blot” puzzles. As additional puzzle sets become available, they will be downloadable from this page. However, those additional puzzle sets require the licensed version of the game, as they aren’t loadable by the shareware version.

The demo is fully functional, but has a limited number of puzzles.

Download the MS Windows demo version
Download the Mac OS X (10.4 or greater) version
The current version is 1.0.


NOTE: The shareware version of the Descartes Rainbow will NOT load the additional puzzle sets. They will only work with the licensed version of the game. So, if you have not yet purchased the licensed version, save yourself the trouble of downloading these files.

The following files contain additional puzzles for the licensed version of Descartes Rainbow 1.0. Simply download and run them to install them in your DR "PUZZLES" folder (AFTER having installed the licensed version of the game!) Then run the game, and select them from the Player-SelectPuzzleSet menu. The default install folder for Descartes Rainbow is C:\EKS\DR. These files would then be installed in C:\EKS\DR\PUZZLES. If you changed the install folder during SETUP, then you will need to appropriately modify the install folder for these files to wherever you DID install Descartes Rainbow.

Many of these puzzles were created and sent to me by users. If you create any you'd like to contribute to this list, send me a copy by email or on disk, and I'll make them available for others to download and play. Also, if you create a color scheme that you think others might enjoy, send it to me and I'll add it to this page too. (See Player-Colors in the program for alternate color schemes, and read the Help screen for more information.)

DR_EXTRA - All of the extra puzzle sets as a single compressed EXE file. (Jan 6, 2010)

The demo and licensed versions are identical, except that the demo version has limited numbers of puzzles, and the licensed version may have additional support files (like extra image sets). So, if the demo version works for you, the licensed version will, too. If the demo version doesn't work for you, neither will the licensed version.

Generally, you don't need to un-install a demo version before installing the licensed version. The licensed version will install right over the top of the demo version and use all of the settings you've already created with the demo version.

NOTE: You can not upgrade your licensed version by installing a newer demo version over the top of the licensed version. You would just end up with a demo version.
