A straightforward edge-matching puzzle game from the Microsoft Entertainment Pack, and an unsolved puzzle with a $2 million prize that went unclaimed. Both are fascinating enough to look into!

Mockton is literally a fucking Bond villian.

@Trusteft 8 лет назад

+Smeddy Too No, he is not literally one. Figuratively perhaps. Literally, no.

Also, a climate change denier

@ITZKappaKAP 8 лет назад

+Deltaexio to be fair sources prove both sides. except initial ones supporting climate change we disproven. Unless you actually mean climate change rather than global warming. many people compare them similarly.

@fuppetti 8 лет назад

Fatigued Potholer54 demonstrates how there is no debate in the scientific community and how Monckton incorrect.

@ITZKappaKAP 8 лет назад

Deltaexio I think its really ignorant to ever believe in it 100%. I believe in climate change but I wonder how much Humans are REALLY effecting it. That still has a lot to investigated and I couldn't even name the numerous amount of study's that changed over time.

@DrRockso79 8 лет назад

That board game version would make a good plot for a psychological horror movie; like everyone that tries it goes insane, or it's some kind of Hellraiser-ish puzzle that opens a portal to Hell; the further you get to finishing it, the more things around the world start getting crazy until it's completely done and the portal is fully opened.

The "most powerful computer" statement was made in 2005. In 2005 the fastest computer was probably IBM Blue Gene clocking at 0.5 Petaflops, in 2016 Tianhe-2 does 34 petaflops. We'll get there eventually.

@Ponicalica 8 лет назад

There's still a million dollar prize related to TetraVex: like many, many other games, an efficient solution for TetraVex at very high sizes (bigger than 16x16) would mean P=NP and would thus be a solution to the corresponding Millenium Prize Problem. Of course, most computer scientists and mathematicians believe it is incredibly unlikely that P=NP and that TetraVex and the many, many problems it is equivalent to in the hardest case are impossible to solve efficiently.

@Ponicalica 8 лет назад

+Mawaru-Ponidrum If you want to read an academic paper on the topic, look up "TetraVex is NP-complete".

Maybe Eternity II can be solved when quantum computers are more sorted out.

@zh84 8 лет назад

There is a lot of mathematical study of edge matching games like this. Look up "Wang dominoes" on the Wikipedia for an example. Very interesting video, of course. Thank you.

@LGR 8 лет назад

Beyond the fascinating prospect of more mathematical studies of edge-matching games... I'm just happy "wang dominoes" are a thing that exists. Great name.

@arcadesdudeTV 7 лет назад

That Eternity II thing is so cool! Back in the day (2004) when I was making TetraVex for my TI-86 after getting hooked on it from playing it in the zipslack Slackware bundle at the time, I had at one point a bug in my code where it would create unsolvable puzzles. I had made it so it would specifically be solvable but must have missed something. It took a while and completely perplexed me why I couldn't solve some of the puzzles in a game I had made (in TI-BASIC)...but I found the error eventually and fixed it so all solutions are solvable. It's super easy to make unsolvable TextraVex puzzles (just randomize the tiles) but not so easy to make sure they're solvable for the whole board.

Tetravex, along with games like Reversi or Backgammon was one of those games that totally felt like the very spirit of Windows 3.11 and then 95. These days most ppl probably think "it's gotta be some sort of Tetris knockoff" when they hear the name, lol

@PolAirity 8 лет назад

Hey LGR, I enjoy your awesome old school reviews and I was wondering if you knew of a game that I used to play. I can't seem to find info on it anywhere. It was a Windows 3.1 game much like connect four but with spheres or balls, and the board could be adjusted as well as the amount of balls it took to win. They had an animation when you dropped them in. It may have came packaged with my Packard Bell so it might be affiliated with them. So if you or anyone else here knows or remembers please let me know. Thanks!

@interghost 8 лет назад

I got the board game and man is it hard!! Good fun though ;) Good review thanks!

@Thanatos420 8 лет назад

This kind of reminds me of Triple Triad from Final Fantasy 8. Only, the polar opposite. Instead of matching numbers to fill a grid, you battle with them to take over a 3x3 grid space. The higher number capturing the adjacent card if it's lower. Thus , the player with the most captured cards and grid space, wins. It feels like Square looked at this and went, 'How do we make that a 2 player game?' and then bam, Triple Triad was born lol.

in my algorithm class we had to proof that a game with the same tiles as tetravex and almost the same rules was PSPACE complete. the difference was that the first row and the last row was given, and the number of rows inbetween and the problem was, is it possible to get to the last row in the given amount of moves. i did the proof via reducing to finite first order logic. but i don't remember how to proof it -.-

@johneygd 8 лет назад

@mirta000 8 лет назад

the solution into making a program that solves this is simple, however it's probably the sheer amount of different combinations that the computer has to try stops it from happening... If it wasn't for the sheer amount of pieces and the fact that they're rotateable, I would say assign a different number to each two-colour/shape combination on the edge. Sure your numbers might go into 1000s, but computer can do number matching.

@LGR 8 лет назад

In other words: it would be easily solvable if it was something else entirely :P

@ccricers 8 лет назад

+mirta000 I've found a similar puzzle to Eternity II at a thrift store but with triangular pieces. Reading the back of the box it says there are over a possible 1^170 permutations for the puzzle.
