The Rules
The "triangle puzzle" is an inverted triangle with 15 holes. To play:
- remove a starting peg from any hole
- choose an arbitrary peg and the jump either horizontally or diagonally over an occupied hole into an empty hole. Here are examples of legal moves:
-
remove the peg you jumped over. Repeat this process until there are no moves left. The object of the game is to end up with exactly one peg.
The Program
To play the game,
- single-click on the starting peg to remove
- for each move, single-click on the peg to move, then single-click on the hole to jump to
- click on the [Undo] and [Redo] buttons to undo/redo a move
- click on [Hint] to have the program suggest a move
- click on the Solvable checkbox to have the computer indicate whether a solution to the puzzle exists after each move you make
- click on the [New Game] button to start a new game
- click on [Solve] to have the program solve the puzzle

Installing/Uninstalling
Installing/Uninstalling
On Win32 Machines
To install, run the setup program. To uninstall, use Add/Remove Programs from [Start Menu] > Settings > Control Panel.
On WinCE Machines
To install, run the setup program on your Win32 desktop.
There are two ways to uninstall. We will assume you're using Microsoft ActiveSync 3.x to communicate with your WinCE device. If you have an older version, please upgrade to avoid going insane, especially if you're running Windows NT.
Preferred Method
- from ActiveSync, choose Tools/Add/Remove Programs...
- select Triangle Puzzle from the applications list (don't try to uncheck it, just select it)
- click the [Remove] button
Alternate Method
On your WinCE device, use Remove Programs from [Start Menu] > Settings [> Control Panel]. This will leave a harmless, spurious entry on your desktop applications list.
Note that it is not possible to uninstall, then reinstall the program using the application manager alone. I don't like cluttering your computer with unnecessary files, so you need to rerun the setup program to reinstall The Triangle Puzzle. The spurious entry in the applications list is due to a shortcoming in the WinCE Application Manager.

Why I Wrote This
Technical Reasons
I wrote the Triangle Puzzle to show off my Palm OS® C++ application framework which is lightweight while still providing:
- an object-oriented framework for forms and databases
- automatic support for program options
- automatic support for reading Memo Pad records with configuration information
- built-in, configurable About and Instruction boxes
- layered event handling

I also wanted illustrate several programming techniques (although most play the game for its own sake and couldn't care less about these techniques):
- Applications can be written in such a way that they survive ports across languages and operating systems with a minimum of change (current supported languages: Delphi, C++, Java; operating systems: Win32, WinCE, Palm OS, and any OS with a decent Java implementation (which, unfortunately, excludes all versions of Mac OS for the time being)).
- Java isn't the only way to achieve cross-platform results, even with a non-trivial user interface. The native C++ executables for Win32, WinCE and Palm OS share the same, sizeable codebase with only a slight amount of operating-system-specific code. What's more, the resultant executables are small and fast (the 8K solution cache increases their size somewhat).
- Java, on the other hand, can be pretty cool when appropriately used. The Java implementation of the Triangle Puzzle runs beautifully on Win32, Personal Java for Windows CE, Linux and HP-UX.
Personal Reasons
I wrote the first incarnation of the Triangle Puzzle on a TRS-80 Model III when I was 14 years old. That summer, we had gone on a family vacation to Door County, Wisconsin and I found and bought the puzzle at a gift shop. I spent that entire vacation unsuccessfully trying to solve the puzzle myself. When I got home, I typed in the BASIC version (here's the listing!) and started it running. It was churning away when my mom called out "Mohan, the pancakes are ready!" and I had to tear myself away.
When I came back upstairs, I saw SOLUTION FOUND: on my screen with a bunch of moves. My first reaction was: "Yeah right," and half-heartedly started making the moves. To my shock, the program had found a solution!
