You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: blackriper.go
    path of file: ./repos/retos-programacion-2023/Retos/Reto #6 - PIEDRA, PAPEL, TIJERA, LAGARTO, SPOCK [Media]/go
    
    the code of the file until where you have to start completion: package main

import "fmt"

// definir metodos de trabajo
type Spock interface {
	StartGame()
	PrintScore()
}

const (
	STONE    = "ðŸ—¿"
	PAPER    = "ðŸ“„"
	SCISSORS = "âœ‚ï¸"
	LIZZARD  = "ðŸ¦Ž"
	SPOCK    = "ðŸ––"
)

// implementar metodos

type Game struct {
	Entrys [][]string
	Result string
}

func (g *Game) StartGame() {
	var (
		p1 int
		p2 int
	)
	for _, entry := range g.Entrys {
		result := BattleGame(entry)
		if result 
    
func BattleGame(entry []string) string {
	var win string
	combinates := map[string][]string{
		PAPER:    {SCISSORS, LIZZARD},
		STONE:    {PAPER, SPOCK},
		SCISSORS: {STONE, SPOCK},
		LIZZARD:  {STONE, SCISSORS},
		SPOCK:    {LIZZARD, PAPER},
	}
	for g := 0; g < len(entry); g++ {
		for _, val := range combinates[entry[g]] {
			if val == entry[1] {
				win = "player2"
				break
			} else if val == entry[0] {
				win = "player1"
				break
			}
		}
	}
	return win
}
