INSANITY

Now we just need 5D chess on a Rubik’s cube with multiverse time travel

Bishop sniping is gonna be even crazier

I always wanted Splatoons added to chess

Finally chess has an update, I've been waiting for decades

Ultimate move of the Universe - solving the Rubik's cube and checkmate at the same time

I gotta say, having the pieces take the longest route possible feels like an over the top flex on the opponent. (IE the bishop going all the way around just to kill the queen, the squid just zooming around in the color,etc) This game, if developed further, would definitely be extremely complicated… and definitely should have ways to mark which tiles are being attacked. I would never be able to win otherwise @~@

imagine trying to play chess when all of a sudden half of the pieces fall off the cube

congratulations, you made the nerdiest game of all time

"Aha, you fool, you will be checkmated in 37 moves with 17 rotations in-between!"

the nature of humanity is just that every so often someone accidentally invents homestuck again.

I love how you just call them “splatoon”, made me laugh way to much, like calling every video game console a “Nintendo”

"The rules are the same as regular Rubik's Chess, except for these changes... wait, what."

At 2:45 the knight could technically also move down one square onto red and then onto the adjecent green square followed by moving in that direction onto the next green square. In regular chess it doesn't matter wether you allow the knight to move two squares in one direction and then one square in any orthogonal direction or first moving one square then two squares. However, in the chess on the surface of a cube it does seem to make a difference which exact type of movement you allow. That being said, the third version of defining a knight move: first going one square in any of the four cardinal directions followed by one diagonal move does seem to be entirely covered by the first two mentioned versions.

This is a really fun concept. One criticism I have is that I think the white and black squares need marked edges or arrows indicating what is the opposing side at the start of the game. This way pawns aren't omnidirectional AND can do their two-long initial move. I hope to see this playable as an actual multiplayer thing at some point instead of a solo chess toy at some point.

This is awesome! Looks great!

I was initially mildly disappointed by how the knight interacted with the corner, as there were other ways an L shape can be folded and laid around the corner. I also wondered how a bishop would handle a direct hit on the corner. As that case was not in the video, pulled up the website myself. the answer is that it just stops at the corner. But this gives some logic that also explains the knight's movement as well. When unfolding the cube always have it be a cross centered on the side the piece is currently on. The Bishop would be moving off the board if it continued straight into the corner, and it blocks any double edge crossing paths the knight would otherwise be able to make, allowing only the ones shown.

FINALLY CHESS BATTLE ADVANCED

This is reminding me of my perennial desire to play Wizards’ Sudoku Chess from MSPA’s Problem Sleuth. Only recently, I obtained wooden checkered polyominoes to play “Broken Chess,” a game of my own invention. But an 8x8x8 cube would be the perfect 3D sudoku grid! And if the pieces could rotate after being placed, that adds the Rubik’s element… it also reminds me of Nitrome’s “Numbskull” Flash game. Of course, the Problem Sleuth version also includes Mario Kart and incomprehensible symbol systems, which would be… difficult to “take seriously.”

I like splatoon, I like my hands, I like chess, I like cubing this is the best!

10:34 what appears to have happened is youve searched the possiblebspace depth-first? Or something like that, when it should be searched width-first (do multiple passes, on each pass only add tiles which are adjacent to tiles we already know are accessible (and bonus, are the same number of tiles as the pass #, from the inkling), and then do multiple passes, until there are no more accessible and unprocessed tiles) By doing that in explicit passes, the linked list will be ordered in such a way that each accessible tile will point backwards to the one space that is closer-est to the inkling (unless there are two, in which case the choice depends on how you ordered the checks within each pass and doesn't ultimately matter), at large resulting in the inkling always choosing the shortest path, because we searched the whole move space in a distance-saving way I know this because I did this for a grid-based fire-emblem-like game prototype with turn-based movement like this. Another trick is to do two passes with the same tiles to get particularly desirable movement behavior. First, add all the orthogonally-accessible tiles, and _then_ add all diagonally-accessible pieces, to the linked list (and the "to check next pass" list) This causes the inkling to "move diagonally first", AKA it will align itself with holes-of-accessibility from afar so that it can moge like a rook, rather than like a bishop, through them. This isnt important here because the inkling has an infinite move speed, but this is important jn my game prototype where your pieces have a limited "speed" and I wanted them to take sane, human paths, and splitting the one pass into two passes in series was the only way I could make the linked list turn out that way. As for the queen's movement, instead of using the linked list each step to determine movement, have the linked list instead determine how you will determine the queen's movement (AKA not a linked list at all, but a list of orthogonal or diagonal directions), where a direction will tell the game which way to "trace backwards until it finds the original piece", carving out the piece's visual movement path, allowing the piece to pass over the same tile in different ways if you choose different destination tiles

We gonna summon a boatload of communities with this one

I think that there are arguably four additional moves rather than the stated two in that knight corner case. In traditional chess moving 2-then-1 is indistinguishable from moving 1-then-2, so one could argue that both should be allowed. This would mean the knight could access the squares diagonally adjacent but around the corner by moving one space onto one side followed by two into the other.

Cary is just the kind of guy to make this, and I love it

I love Splatoons. My favorite Nintendo characters next to Zelda, Metroid and Kid Icarus.

Bro created chess³

So awesome! Have you thought about adding another game-option that allows players to use their turn to twist one of the rubiks cube slices INSTEAD of moving a piece? That way you could also use this to set up a "normal" game of chess, with just the addition of a cubic board, moving pieces around corners and manipulating slices instead of moving. I could imagine lots of chess players making content about that version!

Cary mentioned Splatoon My life is becoming more complete every day

When you said 'Black Knight' and showed a picture of Batman instead of Monty Python and the Holy Grail's 'Black Knight' my soul hurt

9:07 In standard chess, you can assume the player being "checked" passes their turn (even though pass is not a valid option in Chess) for the purposes of determining check. There are plenty of positions in standard Chess where blocking check is the defender's only legal move (even without assuming the "you must block check" rule didn't exist). In short, you would only need to check 1-ply to determine if an enemy is in check. 2-ply is only needed for determining which defender moves are legal. However, for a reasonably optimize script even that 2-ply check should be doable quite quickly.

Cary just does things and i love it

so many years watching your videos and you continue to surprise me. amazing video, what a fascinating concept!

2:47 Along with the 2 options you mentioned you can also go 1 down the red and 1 across. This is because you could go 1 down on green and 2 right towards red. But again... code lol

The classical piece makes it sound like there is something tragic about this game you made. It really gives a lot of the video a somber tone.

as someone whos been a huge fan of yours for a long time, and, unrelatedly, super into speedcubing, this was a super cool video to watch. this is a super cool concept and i cant wait to see what people do with it :D

Love this. Been getting into chess the last few months, great timing!

I love it. Every time i see youve made something new i just know its going to be 🔥

I'm glad that you made that note at 2:45. Because I was going to call you out on this. But apparently you were aware of the additional spaces.

I like how you made this version of chess, although I had a similar idea where it was just a Rubix Cube puzzle, and the solved state is 5 of the 6 sides show different forms of checkmate.

This is so cool! I like the new splatoon pieces :)

I wish Cary got as many views as he deserves. He might be the KZfaqr I get most excited about when I see a new video

One feature I think would be really good is to make a custom rubiks cube size, like, what if I want an 8x8, or an 8x16x4. Although you would probably have to add some checks for if the pieces hit a backfase.

5D Chess on a Rubik's Cube with Multidimensional Time Travel

On corners, I think pawns should be able to eat a piece on the same space in the opposite side, I.E under it directly because pawns can eat diagonally and that space is actually missing, if you look at it. I also think this should apply to bishop and queen whenever they are on a diagonal line from the middle

I'm not a smart person or a coding person or a rubiks cube person. I'm the dingy who just watches Cary in amazement but dawg THIS IS ANOTHER LEVEL

I'm obsessed... I need to play this

my brain is going to explode

6:00 certified banger video moment your videos are so funny and interesting and inspiring i love it!

The long wait for a new game of yours was worth it!

This is the game I didn't know I needed

such interesting videos. gotta love this channel

I love that pieces always take the longer of the two paths, extra style points.

I love you for showing this 5:51 explicitly

Very cool! I saw that giant cube there! :D

Wow, great job. 👍 If someone were to become very skilled at this version of chess, they would probably trick me easily.

You should make the color intensity alternate or something like that so to have a chess-like board visual again even with colors. This would help with moves, especially the diagonal ones

This is really similar to a version I was trying to make in Unity several years ago, except my "extra sauce" was the board is volumetric. Meaning the pieces can traverse INSIDE the cube, making all kinds of weird 3D diagonals and such, with new pieces being better suited to that, like ninjas etc. It's so cool to see a (mostly) working version of this with a whole different twist! (Literally 😂)

It would be fun if, graphically, if a piece had multiple ways to get someone it got split up and parts of it went one way while the others went the other way

SPLATOON CHARACTERS.....

Can’t wait to play this in a real life tournament

Chess. On a Rubik's Cube.

If you keep this project going, I'll be excited to see more updates!

That’s incredible! Great idea & execution! (Okay the execution could use some work 😂 but it’s actually incredibly impressive!)

You just put my two favorite hobbies together. You’re officially the coolest person ever.

Pawn be becoming a king with this one

The memes in this video sent me Great job Cary!!

I would love to see this with other variations of "chess-like" games, like Hnefatafl (viking chess), Martian chess, tank chess, etc. and seeing how people could provide unique variations to those games

Cary really loves doing anything💀

I think it would be fun to try a version of this that is only 3x3 with a few pawns that can only go forward, like normal chess. That would be more simple, but allow for some tricks with twisting the cube to move the pawns around. But you would have to indicate their direction somehow

Hey if you polish this up a bit and make each side checkered with their respective color, I could see this being the new chess! Naviary is making an infinite chess game and it’s so fun to see even cooler chess versions!

This is awesome. Thanks for making such a weird fun crazy thing!

2:48 - A problem with how the Knights move. A Knight on the corner should be able to see more squares. If we're going by the traditional chess rules of 2 squares along, 1 across, then when dealing with corners the geometry should allow a Knight to access more squares than you seem to have programmed. For instance... In the timestamp provided, the Knight should be able to see the Red and Green squares two squares down from where it is. By moving two down on the Green, then one across onto Red, it lands as if it just moved 2 down on Red. By moving two down on the Red, then one across onto Green, it lands as if it just moved 2 down on Green.

No KH pun? man, so close to finishing my march 2024 bingo! (ok but seriously, the chess cube idea is insane!)

I find it kinda weird that the horsey is the only piece whose moves can only go around edge of the cube. I get that taking different paths along the square grid that usually lead to the same target can land on different squares if they go around different 3d edges. But if we assume that the horsies move along a straight line from their starting square to their destination, like any other chess piece, those destinations stay unique on the 3d cube. So horsies would once again have 8 squares they can move to, regardless of where they start.

this has been a dream of mine for years. great job

Cary 20 years later: I programmed REAL LIFE!!!

so glad we've returned back to these wackies

I absolutely love it!

The knight at 2:50 has at least 4 more move options in that position

cool game would love to see it a bit more fleshed out im also sure someone would recreate it in vr if it get really popular

I have been obsessed with cubing, Splatoon 2 and Chess at different points of my life. I never could have possibly imagined they can be combined. Just wow I'm impressed you even managed to build it

COOLNESS!! Im def playing this with my brother

I'm already playing 5D Chess and as a result the movement of these pieces seem so ordinary even on new surfaces. It's the same dimensional moveset they've all had all along aside from the pawn who definitely got an upgrade since it doesn't have any promotions.

Bro, you combined my two favorite things of all time. It's like a wet dream come true

As someone who can solve a rubix cube and loves chess this is an absolute win

This is actually a really cool idea I don't think i would have thought of it

How about giving an option to also scramble the cube randomly at the beginning? Also, some reward for solving the cube during the game? I don't know what that would look like, but I find the idea interesting that splatoon characters get better and better the more solved your board state becomes.

nice, 2 of my favourite hobbies combined

this is such a good concept omg

Cary this is the most crazy and chaotic but beautiful thing I’ve ever seen

Going the long way when possible is probably the coolest way to move. So keep it.

i would love this on steam tbh

I wonder if a smaller, like a 5x5 or even original 3x3 with fewer pieces would still be proper playable, while not be totally over-complex for beginners. I think refining the idea a little and removing figures you don't particularly need on smaller boards might really kick this off! Anyways, very cool idea!

This is a really cool idea!

You're playing checkers while I'm playing 3D chess. "Don't you mean 4D chess?" "No."

That looks like a nightmare to keep track of, but still a ton of fun.

I've had this idea before thanks for making it a reality

Nice... Soo... when does the time travel get implemented?

That is really interesting and incredibly complex

Genius, this is exactemy what the world needed !! No joke this is so creative. I give you an idea for a futur video but i think you can celebrate this achivement already. Idea : chess on a klein bottle (with special rules when pieces meet upside-down) Idea++ : chess on a RUBIKS klein bottle (the mechanism is up to you...)
