There are three ancient forms: Rock, Paper, and Scissors. In Rock Paper Sweeper, you play on a 6×6 grid where each tile bears the symbol of one of these forms. At the start of the game, you will choose one of these forms, and you may change forms throughout the game. Your goal is to reveal all tiles in the grid, but if you reveal a tile with a form that defeats your current form – for example, if you reveal a Rock while in the form of Scissors – then you will lose!

Thus, to reveal a tile safely, you must deduce which symbols might be present on the tile, and reveal it while in a form that is not defeated by those symbols. To allow these deductions, most squares, when revealed, will show the number of adjacent tiles that have the symbol. All boards are built so that they are solvable by deduction alone, without requiring any guessing.

A more detailed discussion of the rules and interface may be found in-game.
