About

RuneChess

Features
Read full description

A chess puzzle with no opponent — only precision. Rune-coins lie on the board. Each one needs an exact number of attacks: no more, no fewer. Your task is to place the pieces you are given so that every rune gets its due. HOW IT WORKS Pieces strike by ordinary chess rules, and a line of attack stops at the first piece it meets. The rook holds the ranks and files, the bishop the diagonals, the knight leaps over anything in the way, the queen combines rook and bishop. The solution falls out of those rules: one attack too many spoils it exactly as surely as one too few. 165 LEVELS Five of them teach you the board and the pieces. After that come Moonlit Garden and Starlit Observatory, where several kinds of piece have to work together and the hints run out. STARS AND RANKS Up to three stars a level: three for an exact solution with no hints. Stars are never spent for nothing. They raise your rank in the achievements and unlock looks — your own table, your own pieces, your own coins. DAILY CHALLENGE A new puzzle every day, separate from the campaign. NOTHING YOU DID NOT ASK FOR The game works without an internet connection. There is no registration, no name or email is asked for, and nothing is sold for real money. The coins on the board are part of the puzzle, not a currency: there is no wagering and no gambling in RuneChess. Advertising is voluntary only: you may watch a video for an extra hint, or to skip a level you are stuck on. Nothing else is hidden behind one.
