Chess Variants

Have you seen people playing what looked like chess but with very different rules? You might have witnessed a game of a chess variant.

What Are Chess Variants?

Chess variants are games that have derived from standard chess. They have at least one main difference from regular chess but can sometimes involve multiple deviations from the original rules.

Examples Of Popular Chess Variants

In the world of chess, there are thousands of variants. Among them, quite a few are widely known and played all around the world.

4-Player Chess

Want to play chess with more than one friend at a time? There is a variant for that, too. Another fun way of shaking things up is 4-Player Chess. As the name implies, you play together with three others. Here's the twist: you are all using the same board. You can play it in a Free-for-All game, or you can team up with another player to battle the other team.

One of the most popular modifications to the game of chess is Bughouse Chess. In this variant, you team up with another player to take on another pair of opponents. Each person on a team plays with opposite colors, and your teammate can use every piece you capture by spending a turn to "drop" it on their board.

Fog Of War

If you're up for an exciting game and are ready to face your fear of the unknown, Fog of War is the right variant for you. In it, players can only see the squares to which their pieces can legally move to. There are no checks, and the game only ends when one of the kings is captured.

Giveaway chess (also known as Antichess) is a variant that turns chess upside down. The goal of the game is to give up all your pieces or force your opponent to stalemate you. The catch: captures are compulsory, so you can't just wander with your pieces aimlessly.

Atomic chess is the right variant for those who like action and explosions. In this game, every capture produces an explosion that affects the pieces surrounding the captured piece, including the attacking one.

In Horde, Black starts with the regular chess pieces while White starts with a horde of 36 pawns. Black must capture all the enemy pawns (and promoted pieces) to win, while White must checkmate the black king.

Another popular variant played all over the world is Chess960, also known as Fischer Random. In this variant, all the rules of regular chess are valid, with only two alterations: every game starts in a semi-random position, which, in turn, affects the way people castle.

King Of The Hill

Have you heard how dominating the center of the board is crucial? In King of the Hill (shortened KOTH), another popular variant, this concept is even more decisive. In these games, you win the game by getting your king to one of the central squares of the board.

Crazyhouse is another variant similar to Bughouse. The same modification to the rule is present: captured pieces can be dropped back on the board. In Crazyhouse, though, you are playing alone, and you can only use the pieces you have won yourself.
