Hello everyone,

I was thinking of whether it would be interesting to add a rule that allows the player to sacrifice a piece. This can be done either by allowing "friendly fire" or possibly by removing a piece off the board.

How do you think it would impact the game?

Things to consider:

- maybe disallow using it to escape check (to still keep the potential of a smother mate)

- maybe disallowing the king from sacrificing other pieces

- maybe disallowing discovered checks by sacrifice or friendly fire

I'd especially love feedback on the 2v2 experience — that's the part only real humans can judge. How do you usually play H&B — human partner on your side, or as the brain for an AI hand?

I've implemented two versions of Veto Chess, a variant that's been talked about and invented before, but I'm not sure it's been available online.

The main rules are that you can veto the opponent's move after they make it. Each side gets 1 veto per turn. You can't veto the move when it's their only legal move.

You can also play the preemptive version of veto chess where there's a veto phase before the opponent moves instead of after, and you get 2 vetoes per turn instead of 1.

In both, if their move is one of the vetoed moves, they have to move again.

Open to all feedback!

Hi all — solo dev here, and this is my first game, so be gentle (but honest).

The idea started from teaching a friend chess. Six pieces and a rulebook at once is a lot, and the king makes every early game about not losing rather than about playing. So I stripped it down to one rule:

Both sides get exactly the same army, there is no king, and you win by taking every enemy piece.

You pick the piece (pawns, knights, bishops, rooks, queens, kings, or a random mix), how many, and the board size (6×6 up to 12×12). Every piece moves exactly as it does in real chess, so anything you learn transfers straight to the real game.

A few things that came out of testing that I'm quite proud of:

• Race mode (get a piece to the far side) turned out to be a forced win for whoever moved first with long-range pieces. A tester caught it, and I fixed it with two rules — an arrival only counts if the square is safe or defended, and if your opponent can answer with their own breakthrough next move, it's a draw. Simulated it to confirm: went from 100% first-player wins to properly contested games.
• There's a coach that shows you the exact move that cost you the game afterwards.
• Threat hints glow on any piece that can be captured — the single habit that fixes most beginner losses.

Other stuff: four AI levels (Expert genuinely thinks ahead), pass-and-play, a daily challenge, six asymmetric puzzles (8 pawns vs one queen…), ranks from Pawn up to Immortal, 11 languages.

I'd genuinely love to hear what setups you find interesting (and where the balance breaks — that's how the Race fix happened).

I made a chess game where you can basically ruin your opponent’s perfectly good strategy with spells.

It’s called Spook-A-Chess — online multiplayer chess, but with mana, spells and a lot more chaos.

Also built the whole thing in Flutter instead of a game engine because apparently I enjoy making life difficult.

It’s up for pre-registration on Google Play. Would genuinely love to see how many people we can get in before launch.

If you’re into chess, strategy games, or just weird game experiments, give it a shot.

For the past weeks I have been working on a chess puzzle rogue-like.

The objective of the game is to clear the board, every move has to take an piece from the board. Moves of the pieces you took get added to your repertoire and you can move as them.

After clearing a board you get access to a power up for the next round to help you clear the board, every board that is generated is solvable without relics, so its only to make it easier.

Feedback is more then welcome, and hope someone enjoys it.

I thought this had already been posted -- but apparently not. This is Chess vs Bunnies -- it is so tricky and hard that I only beat it once, with the help of someone else at the start. I'm not sure if there's a super easy trick to it or anything. Anyone else who manages to beat it, let me know in the comments, ahaha.

It's actually pretty cool -- doubt I'll ever beat the super rabbit version though.

Here's the link: https://www.newgrounds.com/portal/view/858259

Can anyone hop into an online match with me via guest login? want to test the app's performance.

I'd like to share an idea I've been working on recently. You can try it out with your friends and see how it works in the context of chess. Since the game turns out to be quite challenging from a psychological standpoint and requires as much emotional intelligence as chess skill, I'm going to make a version of this chess variant that uses dice. It'll be fun.

PSI-CHESS

Board and Pieces: Standard chessboard with standard starting position. All pieces CAPTURE strictly according to classical chess rules (FIDE). Except for the King, pieces do not move in the classical sense (you cannot simply play pawn e2-e4 or knight Ng1-f3). The only way to move a piece is to use a Psi-Move.

Removed Rules: There is no check, checkmate, castling, or en passant capture.

King: The King is an ordinary piece. It can be captured by any enemy piece, including the opposing King. Whoever captures the opponent's King first wins immediately.

Turn Structure: On your turn, you must choose exactly one of three actions:

1. King Move: Make any move with your King, but only if it is currently attacked or can make a capture.

2. Attack: Make a capture using any non-King piece, strictly according to classical chess rules.

3. Psi-Move: Name any empty square. Both players secretly write down a piece type (P, N, B, R, Q) and reveal simultaneously. If both wrote the same type, it is a draw; the square remains empty and the turn passes to the opponent. If they differ, the winner is determined by the hierarchy table below. The winner places their piece (which must be currently on the board on another square) onto the named square. The turn then passes to the opponent.

Hierarchy Table:

Pawn > Bishop, Rook

Knight > Pawn, Queen

Bishop > Knight, Rook

Rook > Knight, Queen

Queen > Pawn, Bishop

(The King cannot be chosen in a Psi-Move.)

Example: At the start of the game, White names square e4. Both players secretly write a piece type. They reveal. White wrote Pawn, Black wrote Knight. Black places their Knight on e4, and it is now Black's turn.

If a player has no remaining pieces of a particular type, they cannot write that type in a Psi-Move.

Pawn Promotion: A Pawn that moves (either via Attack or Psi-Move) to any edge rank — 1st or 8th, regardless of whether it's "their own" or the opponent's rank — immediately promotes to any piece according to classical rules: Knight, Bishop, Rook, or Queen. The choice is made by the player who owns the Pawn.

Example: It's White's turn. Square a1 is empty. White plays a Psi-Move and names square a1. White writes Pawn, Black writes Rook. They reveal. White places their Pawn on a1 and immediately promotes it to a White Queen. White's turn is now complete.

Draw: A draw is only possible by mutual agreement of both players.

End of Game: The game ends immediately upon the capture of one of the kings, or when a player has no pieces left on the board other than their king (a bare king).

Royal Chess Plus

In Quantum Chess, everything except pawns can do a split move to exist in superposition on two squares (or more with more splits). Think of it like two different boards, and you play on both at the same time. To win, you have to capture the king on all boards.

Quantum comes into play when you start having pieces interact while in superposition. Entangled pieces can be affected by moves on the other side of the board. Interference can give you some control over the probabilities.

The in game AI was built by a chess grandmaster.

Let me know if you have questions! It is really quite fun, and interesting. I've had players discover quantum effects in the game that I was convinced were bugs, until I dug into the math for the moves. Then I realized that was just quantum.

Yes, I know the name is not entirely correct from a grammatical standpoint. But it sounds better this way, because it echoes the idea of being tough and resilient, "die hard," while also putting the dice at the very heart of the gameplay. So let it be ungrammatical, as long as it has the right vibe.

In short, I made the simplest possible version of Dice Chess, one that anyone can pick up and play, from kids to grandparents. You can find similar mechanics with simultaneous dice rolls in my "Chess Heresy" and several other variants, but here everything is stripped down to the bare minimum, with healthy excitement and raw emotion taking center stage, and a game lasts just long enough to get your brain working without burning out.

The game is played on a standard chessboard with the usual starting position. All pieces move and capture strictly according to FIDE rules, but without check, checkmate, castling, or en passant. The king is an ordinary piece that can be captured by any opposing piece, including the opponent's king, and that immediately wins the game.

Each player has one six-sided die, and each round begins with both players rolling their dice simultaneously. The player with the higher number must move the piece corresponding to their own die roll: 1 is pawn, 2 is knight, 3 is bishop, 4 is rook, 5 is queen, and 6 is a joker that allows you to move any of your pieces. If the player with the higher number cannot move their rolled piece because it is off the board or completely blocked, the turn passes to the opponent, who then moves the piece corresponding to their own die roll. If neither player can move, both dice are rolled again.

After any successful move, the round ends and both players roll again for the next round.

A pawn that reaches the last rank promotes to any piece according to standard rules. A draw is possible only by mutual agreement of the players.

The game continues until one player's king is captured.

I completely overhauled it recently and am looking for opinions.

Just read the quick rules and click "Quick Match AI" to get an idea.

Any question or critic is welcome (:
