Trianglons Puzzles (aka Trigons)

Welcome to Trianglons!

"Like sudoku on steroids. Massive, massive amounts of steroids." - Walter White

Trianglons is a program used to solve challenging math and logic problems [aka Trigons].

How the puzzles work:
Fill in the numbers 0-6 in each triangle edge so that the numbers in the
three edges add up to the number in the middle. Since many of the edges
are shared with two triangles, logic needs to be used to figure out the
correct number for an edge. Example: a 4 triangle next to a 16 triangle
will have a shared edge of 4 (as 4 is the largest number in the possible
combinations for 4 triangles and 4 is the smallest number in the possible
combinations for 16 triangles).

6/13/2021 I did try to modify my old program, but was not able to get it to compile with a later version of Java (only spent a couple of hours on it - if there wasn't a quick solution, wasn't going to spend a lot of time on it). Maybe one day I'll spend more time trying to get it working on newer Java or (even better) re-write in a different language.

However I do occassionally get an email asking/begging for more printable puzzles. So, building up some good karma, I saved off (have a computer with an old version of Java and I can play my puzzle program) a bunch and uploaded them. My save program as a glitch with a few of the puzzles so you will see there are a few puzzle numbers missing. But for your puzzling pleasure:

    Security issue:
    If you get a security warning or error trying to run Trianglons: Java upped their security with the January 2014 update and you may now have trouble running Trianglons - but there is a workaround. [If you are concerned with security: Trianglons does not read or write anything, everything is internal.] To get around the security issue, you need to open the control panel on your PC and open up Java and lower the security settings to medium and then add "trianglons.com" to the trusted sites list and then restart the browser.
    10/18/14 New Java problem: I've been informed that the latest version of Java is again blocking the Trianglons program and the above workaround is not being allowed. Don't have a new workaround yet and suggest that you DO NOT update Java whenever they come out with a new version if you have a working Trianglons and want to make sure you can continue to run it. If someone figures out a workaround, PLEASE let me know!
