Get your king to one of the four central squares and you win instantly.
Standard chess with one addition: if your king reaches d4, e4, d5 or e5 and is not in check, you win immediately. Checkmate and all normal rules still apply.
King of the Hill turns the safest piece on the board into the most aggressive one. Every plan you have ever had about king safety is now in tension with a second plan about king activity, and holding both in your head at once is the whole game.
d4, e4, d5 and e5 are the only squares that matter. A knight covering two of them is worth more than a rook on an open file.
This is an endgame race disguised as a middlegame. The fewer pieces on the board, the safer your king's march becomes.
Genuinely — a king on e3 supported by pawns is both a winning threat and a strong piece. It feels wrong. It is correct.
You cannot usually catch an advancing king. You can put a pawn or a knight on the square he needs.
Count the moves. If they arrive first, you have lost — there is no consolation prize for being close.
Trading queens looks safe and often hands the opponent a free run to the centre.
A single check on the winning square resets the whole plan — that is your main defensive resource.
Standard chess teaches you to hide the king for forty moves and then suddenly use him. King of the Hill collapses that into one game, and the instinct it builds — that the king has a value and a job — is exactly what wins endgames.
That is the argument for variants generally, and it is worth stating plainly: a variant removes part of chess so that what remains gets your full attention. Played casually they are a pleasant break. Played deliberately — naming the skill first, then going back to a standard game and finding the same idea — they are the most efficient training available, because you are practising one thing at a time instead of everything at once.
Players who want a completely fresh win condition without learning new piece movements. The easiest variant to pick up in five minutes.

Each variant isolates one skill and drills it harder than any exercise. The coach's guide to variants covers which one to use for what, or see the trainer classroom.
