Hm. I'll make the end condition configurable so you can pick that as an option. Right now I'm stuck at a second refactoring but the idea is to give the player flexibility on structuring the game when they start it. Right now the end-game routine is a very dumb implementation.

    // meaning all tiles are touched or marked
    // and guesses are correct
    is_board_solved() {
        for( var k in this.board.public ) {
            
            // takes a single unguessed, unrevealed tile
            if(
                this.board.public[k].state === "unknown" &&
                this.board.public[k].guess === false
            ) {
                return( false );
            }

            // or one wrong mine guess
            if(
                this.board.public[k].guess === true &&
                this.board.private[k].mine === false
            ) {
                return( false );
            }
        }
        return( true );
    }
