These Knight's Paths Confuse Me 

9:13 As far as I'm aware, the two-tile-move was because a lot of games ended up opening with the same Pawn being moved forward twice on both sides, and then En Passant was later introduced because people were using that two-tile move to bypass enemy Pawns when they otherwise wouldn't be able to. In other words, their removal is entirely justified in this chaotic variant.

7:42 Oh boy! I can't wait to promote my pawn into another pawn!

I would recommend adding an option to start with the cube scrambled and if you solve it you win in addition to getting checkmate.

Now my brain is melting trying to imagine 6D rubik's cube chess with multiverse time travel.

It's interesting that the FIDE definition of the knight's move is not equivalent to the two and one tiles definition on a rubik's cube. The FIDE definition says that the knight moves to the closest squares that are not on the same rank, file, or diagonal so, some of those moves wouldn't be legal if you used that.

Per official chess rules, this update made it wrong where it was correct before. The FIDE rules state:"The knight may move to one of the squares nearest to that on which it stands but not on the same rank, file or diagonal." So in fact, what everyone told you was wrong and you were right by accident.

That confused you? This entire game confuses me!

12:14 Gotta love how white wins the game before it even starts

cant believe carykh created the battle between light and dark at the heart of skaia

8:15 On this point, there are cases in regular chess where under-promoting to rook is better. Promoting to queen may result in a stalemate in an otherwise winning position.

legit forgot this was somewhat of a sillypost until i remembered the T-Posing Inklings

The reasoning behind en passant and pawns being able to move 2 steps on their first turn was a way to speed up the game and get into the middle game more quickly. I feel like it's fair to remove those rules here as pawn structure doesn't seem that important and the game is already complex enough at the beginning, it doesn't need to be sped up.

you should make knights, nootnoots, and amazons be able to jump over the walls in a walled game

8:12 because sometimes promoting to queen will cause a stalemate. with 6 sides, there are way more diagonal tiles to keep track of when choosing the queen instead of the rook so maybe underpromotion is a better option to save time thinking in the end game. anyway you should just make the promotion options a setting in game setup.

In fact, many people forget that the Knight move is not just an L-shaped move. The Knight's move includes "jumping" (since it can't be blocked by other pieces) to the nearest squares that are NOT horizontal, vertical or diagonal, as it works for the Rook and Bishop (or Queen, if you combine them both). Therefore, I even see more logic in the old knight move system, as the new added options are Bishop-like (while the Knight does not repeat the movement capabilities of any other piece, being the most tricky one).

I almost want to mod the comically long splatoon pathfinding back in tbh

0:18 it's a smile. 11:25 it would be cool if the hand could remove one wall for one turn.

You should make it where you can promote to a queen or Amazon only if you don’t have one already, that way you can make a comeback if you lost them but not gain an advantage by getting a stockpile of them

update 10 can mean multiverse time travel. which will only make the game even more like homestuck.

The rest of the cube confuses me even more. Having literal hands and Splatoon Inkling Girls in there feels so... wrong. What's next? Pinkie Pie?

Putting a small rotation on the board is a brilliant way to enhance readability using parallax.

13:24 Actually bishops still only have 50% coverage, the only thing that changes that the color is inconsistent, thats all

I think the nootalps are good to encourage use of scrambling, but I feel like having both them and splatoons at the same time is too strong - you're rewarded for being on an early game cube, and you're rewarded for being on a late game cube. What if the board started semiscrambled, but one colour has splatoons and the other has nootalps so each side is trying to get the cube to either state. Maybe that would be a bit unfair to the solving side though since they're having to actually think about solving while the scramble side just makes any random moves. Also I think hands are becoming too important as they're the only pieces that can turn the board, and especially the new walled games that becomes absolutely necessary. If you manage to get your king on its own face, you can just target the enemy hands and it becomes at least a stalemate if not a win.

Two piece suggestions: archbishop, chancellor (B+N, R+N) Also, just wondering, is there stalemate in this variant? Example of a position in regular chess when promotion to a rook is the best move: White Pg7, White Kh4, Black Kh6 The best more here is for white is g8=R, since g8=Q would be stalemate.

Having bandaging on the Rubik’s cube or even cuboids would be rly cool too (maybe even mirror cubes where each slice has different sizes and if a hand turns a size, you can move onto those new exposed sides, and if a piece is on it when it’s turned, all of those pieces get captured, including your own ofc

The knights movement reminds me of a knights tour variant I made where the squares of the board were different sizes. So a knight on a 2 by 2 square surrounded by 1 by 1 squares could move to 20 squares. It got so cursed when mixing 2 by 1, 2 by 2, and 1 by 1 tiles

You might know me, I've been following your work for awhile. Your interest in problem solving and innovating the conventional has been super inspiring to me as an artist. Now, at the ripe age of a year plus your current age, I'm inching towards a career that has more computer science involved in it, because you made me desire having that flexibility in my life. Everything is a nail and a hammer, and in that sense, it's art. It's the little things, like that esoteric last sentence, that are the daily creative endeavors that keep my life full. If you have any doubts, know that your work has meant the world to me in these pursuits, and I hope you find something in that. Keep being you.

It would be interesting if pawns could only move towards the nearest tile of the opposite color. It would probably suck though.

There should be a gammemode where the cube is randomized and each player tries to solve the cube while playing chess

I'm surprised Cary didn't know that the chess community cares a LOT about it's ability to under promote to the minimally viable piece for maximum swag 😎

Petition to add a piece that walls off it's side of the cube. Each side starts with one, and it would be a good mix between the walled mode while still allowing regular cross-board interactions.

10:26 5d chess with multiverse time travel

Pawns' two-tile first move and en passant in regular chess feel arbitrary because they were essentially just house rules for speeding up the game which stuck. You can move two tiles on the first move because the first few moves of a chess game would otherwise almost always involve moving the same pawn multiple times before you can do anything else. En passant exists to patch the subsequent ability of a pawn to skip past an opposing pawn without it having an opportunity to capture it, since it would be able to without the two-tile move and it's only supposed to speed things up, not affect the strategy in any way. All this to say it makes perfect sense not to include those here since they're basically just hotfixes for a situation that arises at the start of normal chess that this game simply doesn't have.

One other update that would be cool is that if you could start a game with the cube prescrambled either randomly or in the opposite checkerboard pattern.

Great video Cary! 👍

Idea here: Make the pieces have less polygons so the game may run faster with bigger cubes (don't remove too many polygons)

Good update. Pingu's inclusion is welcome. 🐧

i like your videos. keep it up!

first time I've seen this series and he's talking about splatoon pieces. Never change, Cary.

I’ve been wanting to make my own chess variant and seeing this makes me want to make more progress!

I think that for the walled variant there should be a rule that lets you transform your most powerful unit into a hand if all of your hands are captured, since you would never be able to attack the enemy king without them

Fun Fact: The ability for pawns to move 2 spaces was created to speed up the early game of chess. This is also why En Passant was invented, to fix the problem that this creates.

Do a "random wall" game, where only some edges have walls.

Great chess variant!!!

8:13 there *are* times to promote to rook or bishop instead of queen. While queens are a typical a “more powerful” piece, they aren’t strictly superior. They attack more squares, but attacking more squares is not the win condition in chess, checkmate is, and attacking more squares isn’t always what you want. The typical example for this is stalemate. It’s pretty easy to construct a scenario where promoting to queen causes stalemate while promoting to either rook or bishop doesn’t. These don’t happen very often in games, but they do happen. More intricate scenarios also exist where promoting to queen allows the opponent to force you to play stalemate on a later turn, but those are hard to construct, and may be hard to notice over the board.

Don't worry, Cary. En passant and the two-tile-move thing only exist in chess to save time, It doesn't actually introduce any actually new moves. That's why it only applies to the first time the piece moves. If both players are just going to move the same pawn twice at the start, Why make that take 4 turns, When you can just cut it in half? And in that case, With the new double-move rule, En passant was introduced to say "No, You don't get to avoid capture by doing that, Because it would have been my turn, And I would have captured you."

Amazing keep It up! ❤❤❤

You gotta make an alternate mode where if a player gets checkmated, they'll be allowed to solve the Rubix cube within a given amount of time, and if they succeeded, they will be allowed to move their king to any space desired (but only once per game. You could even make the time you have to solve the cube tie into a turn clock system, so you actually eat up the time you have left even if you succeed).

This is such an interesting way to play chess what a creative fun and inventive game!

I would just call your additional piece The dragon.

Old inklings movement was kinda funny, i hope you will add an option to change it back

What an advanced chess battle

That night was always confusing, even in the second dimension

10:27 You don't want to create 9D rubik's chess with multiverses and time travel?

My grandad loves both rubix cubes and chess, I need to show him this!

9:55 5D Rubiks Chess with multi dimentional time travel

This is really inspiring!

The Bishop should be allowed to teleport to the opposite face when it hits a corner. Something about stopping it dead in its tracks goes against the spirit of the game.

hahahaha! Alpine penguins! That'd be something to behold.

YA GOTTA LOVE THIS!

No no keep the branching option, and give TRUE "5D chess with parallel dimension and time travel "

at first i was like why rubick board but then i was like :O this looks amazing! it just need a little finishing and add background and it is ready to go!

Fix this: Splatoons are called hands when checking a king

now we just need 5d rubix chess with time trawel

9:46 I love this refrence to antimatter dimensions lol

this is incredible !

it'd be cool to have a gamemode where the cube starts scrambled and an objective is to solve it. it could be a side thing like pawn promotion or one or both players could have it as a win condition. prolly only any fun on the 3x3 and other small cubes

and ofc I discover this right after school ends

Battle for Chess Cube

While it makes the mechanic easier to understand from a user interface and tactics standpoint, I feel like having rotating tied exclusively to the hand pieces makes the mechanic feel isolated from the rest of the game, especially when the hand piece's only purpose is to interact with that one mechanic. I think a better way to incorporate rotating would be to remove the hand pieces, and to instead have rotating be a mostly unrestricted action. It could be performed by selecting one of any of the tiles on the cube with right-click, and then have the player select one of four cardinal directions to rotate the tile in by 90°. To make doing versus not doing it a meaningful choice, I'd make it so a player can't move a piece and rotate a slice in the same turn. Overall, this should give rotating the same significance as in walled chess, but without reducing the mobility of every other piece. Also, to give Splatoons more agency later in the game, I'd give them the ability to convert whatever tile they move to into the color of whatever tile they moved from. This allows them to be moved strategically to increase the amount of "turf" that's in their team's color, potentially reducing the mobility loss from the cube getting progressively scrambled. The Nooter can have a similar buff in the early game by giving them the ability to convert the color of the tile they move to into any random color that they didn't encounter on their path to it. This buff assumes the Nooter can move cardinally by one space in a color block like a Splatoon can in a color change.

You should have called the splatoons inklings and the pingus octolings.

> What about Update 9? There is no Update 9. Ah yes, Antimatter Dimensions

8:13 Maybe people would promote to a weaker piece to avoid a stalemate.

A sequel? Cool!

There is actually a case in chess where you promote a pawn into a rook/bishop: when a queen would cause the game to end in stalemate. But that’s such a niche case that I like the idea of not allowing queen (and amazon) promotions.

You should have knights be able to go over the walls, like how they can jump over pieces.

I'm joking here... why not spawning pawns? Then introduce a minefield, and have parts of the cube explode when mines are not flagged in time by a minesweeper pawn, making the shape irregular and the moves even more complicated. Of course each pawn needs a backstory and a "damage" level. Also introduce a poisonous lizard: it has feet on multiple squares and it can walk on mines.

There should be a toggle that displays how much pieces each square is protected by

Rocky getting into the final 6 in BFDI confuses me even more.

sometimes in chess there is a reason to underpromote your piece (choose rook or bishop over queen) and that is to avoid stale mate

I just remembered that the splatoon piece exists lmao I love Splatoon (Fav game c:)

We need an online version!

For the nootnoot being too strong, my first thought was to nerf it by keeping the old behavoir, but with a new rule where it can never touch the same color multiple times in the same move. So same idea, but it can never move more than 5 tiles away since there's only 6 colors total.

Suggestion: support for the colourblind, as a bonus makes the colourseers have an easier time reading the map

The pawn double move is to speed up the game since without this rule, it takes a long time for pawns to come in contact with each other and early aggressive pawn play (including almost every gambit) becomes pretty much impossible. En passant fixes an unfortunate side effect of the double move rule, namely the ability to move past an opposing pawn to avoid an exchange, which if abused leads to very boring, closed positions where neither side can make progress because the centre is clogged with pawns that can no longer capture each other. With en passant, for two pawns on adjacent files to move past each other, one player must offer a trade and the other has the chance to accept it, meaning locked down positions only happen if both sides are okay with it. For a dozen reasons none of this is relevant in Rubiks chess though.

8'18 Speaking of queen, What about cases in normal chess where promoting to a queen would be a blunder and result in a stalemate because the opponent wouldn't have any squares to go to?

2:38 what does "diagonal" mean to the bishop going around the corner anyway? Much like your knight behavior at the corner I think there might be some possible shenanigans depending on how you define diagonal. If it's two squares connected by a corner then you could theoretically jump a corner of the cube with a bishop. Alternately, think of diagonal as a very short knight's move of up-one-over-one and now a bishop could move to an adjacent face at a corner

What happens when a diagonal move directly hits a corner? Does it split or stop?

you should add a mode with a lot of hands and to win you have to unscramble the cube

Add 5d multiverse time travel

Nice video cary

idea: use the inside of the rubiks cube as another board

FIFO queue.... this really is a homestuck game

OH MY GOSH I thought it was just cube chess but it MOVES.

1:43 unprototyped skaia session

Is okay to refuse to become human once again

Do it! Add the 5D Chess mechanics! We need to go deeper!

8:15 "if the queen were an option, why would you ever pick a rook" stalemate, there are some positions where promoting to a queen can cause stalemate but promoting to a rook can lead to an eventual mate, im not 100% sure this is the case for rubiks chess, but its very likely

An easy way to find all the moves is to form a net for the 3 faces of the cube and register all moves on all nets

Hey Carykh do you did The Amazing Marble Race Season 3 Leg 10?
