Impressions

After a too brief look at Trinagon, a guy told me : "Hey, why don't you 'just' compute all the possibilities ... " 
... hinting that this would lead to the obvious solutions.

Well. Sure. Not that the first would be so hard. But the other ?

So. After making the not extremely big effort to calculate all those permutations on the puzzles, the conclusion is :
There are often too many for our limited resources to compute : Septillions or so (a trillion trillions). 
These puzzles often DO have more permutations than the rubiks cube does.

Fortunately, this is not always the case, some puzzles have just a few hundred, or thousands or hundred thousands.
In that space, it is possihble to find perfect solutions, by letting the computer play (with medium algorithmic intelligence)
So. Now there are real absolutely perfect solutions for many puzzles available ! 
Does this give a clue to how hard they are : NO, not really. Its not that straightforward.
but  that's another story ...

What Others think about Trinagon :

• ".. a Rubik's Cube of the 21st Century... "  - APKBomb
• "..  help in a fascinating way to pump logical abilities, intelligence, ingenuity and teach to think outside the box. .. " - APKVision

One of the playgrounds in Trinagon is the dual body to the cube, the octahedron.
The octahedron has as many vertices (corners) as the cube has faces, and vice versa.

If you visualise the triangles being the cornerstones of a cube you will see a 2x2 rubik's cube.

A mathematically completely identical puzzle to the Rubik's cube can be seen above.
The only difference is the absolute position of the triangles, whereas the corners of the 2x2 rubik's cube are solved relative to each other.

 In honor of the Rubik's Cube, we made a few puzzles using 8 colors, which correspond to the 8 corners of the cube, and therefore resemble the 2x2 cube the most, and named this collection after that fact.
Shuffle those to play them rubik's-cube-style.

Trinagon also offers easier variations and a few symetrical patterns that have secifically been made to resemble the typical problems coming up when solving a rubik's 2x2 cube.
That is why they almost look repetitive, but aren't. Each offers a different 2x2 cube-dual-problem to solve.
You might even learn some new tricks on these, and find more elegant ways to solve the cube.

Here they are. From easy to hardest. More of them may be made.

A simple color exchange. The triangles are exactly opposite their solved positions.
With no faces or direction markers on, this puzzle can be solved rather easily.
Puzzle Nr. 152532
Difficulty : 20
Rotator Type 1

Best solution : To be seen... by  AnonyMouse, 23.11.2019

The same as the previous puzzle but at the same time the faces have to be switched.

Puzzle Nr 183953
Rotator Type 4

You shall find out how much more difficult this one is compared to the last. Maybe not by much ?

Best solution : ....

Here the pieces end up at the same spot, but with their faces switched.
Only the solution (in the corner) is different.

This puzzle is less obviously like the rubik's cube, because the cube would only use rotation type 1.
Also for an extra challenge two rotators are missing !

Puzzle Nr. 465970
Difficulty : ??
Rotator Type 1 & 4

Best solution : ....

The third step on the same theme, with face and directions active !
The triangles sit exactly opposite their intended location. They are directed 'up and down' to the black rotators.
Maybe a similar pattern to solving it exists as in puzzles 152532 & 183953 ?

Puzzle Nr. 379894
Difficulty : ??
Rotator Type 4

Best solution : ....

Now it gets a bit harder. Here the red, green, purple & grey triangles are already there, but yellow <-> orange & blue <-> pink need to be exchanged.

This is one case where a color-only puzzle is not easy anymore. The cube-duality is the reason for that.

Puzzle Nr. 623675
Difficulty : 40
Rotator Type 1

Best solution : ....

Mathematically identical to the rubik's cube, with only rotation 1 in use, and directionmarkers active.
The symytry is the same as puzzle 379894, i.e. the triangles simply opposite their intented spot.

We're not sure if this one is harder or easier than the last. The specific symetry may make it easier ? (we know, but won't say :))

Puzzle Nr. 048838
Difficulty : ??
Rotator Type 1

Best solution : ....

If you want to play 2x2 rubik's cube style, shuffle this one. It sould be possible to solve in 14 moves, at least by a god, or maybe by you.

These next three puzzles have not been solved yet :

Same as puzzle 623675, but facemarkers active and playing with mixed rotations.
This puzzle would impossible, if not for the face-preserving rotationtype in it.

As it is, it has not yet been solved !!!  but theory alone claims that it is solvable !
Feel free to send in your solutions !

Puzzle Nr. 616545
Difficulty : actually unknown, since it has not been solved, but designed from theory.
This one is likely harder than the two below. 
Rotator Types 2, 4 & 6

Best solution : tba

Same as puzzle 048838 but with the color-symetry of 623675, i.e. four colors have been switched.

Also unsolved. Theory says it is, and we'll be happy to put your name under it. 

Puzzle Nr. 605522
Difficulty : as hard as a shuffled 2x2 rubik's cube with absolute positions.
Rotator Type 1

Best solution : tba

Another Variation on switching colors. This one switches 4 colors vertical (vertical = between the black rotators, one defined as 'up' the other as 'down') and the other 4 colors horizontally.

Puzzle Nr. 564784
Difficulty : most likely harder than the one before ?
Rotator Type 1

Also unsolved. Theory says it is, and we'll be happy to put your name under it. 

Best solution : tba.

Trinagon was born in a different time (like 1988 -another millenium / century). 

A time where the average attention span used to be more than 5 seconds.
A time when immediate gratification was not the norm. Rewards had to be earned. (They actually still do - at least real rewards.)

Games, regardless if in real life or in virtual, needed an effort to learn. Nothing ever was self explanatory, and you were lucky, if there were any explanations at all.
Reading a book, getting deep into a story, and exploring with an active mind was necessary. Having to suss things and life out mostly on your own.
Whenever we got a new game on our Commodore 64, we always quickly went through all the keys on the keyboard to find out if they had any functions :)

Now compare that to the games kids aged 5 to 11 get delivered.
The 'game', often nothing more than a simple-minded tapping or shifting / moving, likely will be boring to a dolphin within a few minutes. (because dolphins are sharp :))
Yet, they offer easy entertainment and quick gratifications.  (Hurraai, you just tapped the red button. Whao ! Boooom. Level 58 solved.) Without those the 'players' will turn away within the first seconds. 
Sure, this IS grossly exaggerated, but there is truth in it.

This demand for easy entertainment and quick gratifications comes with a price.

A high price.
It is the expectation for everything to be easy, expectation to be lead every step on the way, and needing gratifications and rewards to keep going, long even before the going could get tough.
It nourishes a specific mindsetting, one that leads to dependence and usually someone else doing the thinking, learning and heavy lifting. And interesting enough, it also includes believing to be entitled to that service. 

If this is your mindset & your expectations :
Forget Trinagon.  It's not for you.

Trinagon will give you a hard time on the occasion. Trinagon will also teach you a thing or two about focus & concentration, applying your brains, spatial awareness & imagination, abstractions &  thinking ahead in abstract ways.
You can grow and learn. You can become.
It's all there for the taking, ... if you reach out.
