undefined method `_path' when using params

I'm new to Rails and currently I'm building a game app. My game contains multiple levels. I want the url of the game to contain the number of each level. For example:

http://localhost:3000/game1/play/1
http://localhost:3000/game1/play/2

In order to achieve this, I understand that I need to use params, here's my code:

routes.rb:

Rails.application.routes.draw do

  devise_for :users

  resources :game1

  get "/game1" => "game1#index"
  get "/game1/play/:level" => "game1#play"
  get "/game1/instruction" => "game1#instruction"


  get "/pages/*page" => "pages#show"
  get "/pages/about" => "pages#about"

  root "pages#show", page: "home"

end

controller:

class Game1Controller < ApplicationController

    def index
    end

    def play

        @game1 = Game1lv.find(params[:level])

        @userid = current_user.id
        @usergame1lv = User.where(id: @userid).limit(1).pluck(:game1lv) 
        if @usergame1lv == [nil]
            @usergame1lv = 1
        end

        @game1l = Game1lv.where(:level => @usergame1lv).limit(1).pluck(:imagelink)
        @game1a = Game1lv.where(:level => @usergame1lv).limit(1).pluck(:answer)
        @game1link = @game1l[0].to_s
        @game1answer = @game1a[0].to_s

        @game1answer_user = params["answer"]

        if @game1answer_user == @game1answer
            redirect_to game1_play_path(@game1), :flash => { :success => "You are right!" }
        else
            #flash.now[:alert] = 'You are wrong! Lets try again!'
        end

    end

    def instruction
    end

end

view:

<body><center>

    <br><b>Answer: </b><br><br>

    <%= form_tag game1_play_path(@game1), :method => :get, :id => "text_form" do %>

        <%= text_field_tag "answer", "" ,class: 'textbox_game' %>
        <br><br>
        <%= submit_tag("Submit", :class => "button_game") %>

    <% end %>


</center></body>

Now when I go to the url: 

http://localhost:3000/game1/play/1

Rails show the error:

undefined method `game1_play_path' for #<#<Class:0x943de50>:0x9447720>

Rails indicate that the error is at this line in the view file:

<%= form_tag game1_play_path(@game1), :method => :get, :id => "text_form" do %>

Please show me what I'm doing wrong and why that method is undefined. Thanks in advance.

As mentioned by Pavan, you can force the path to be defined your way using as: :path_name.

Before that, I would have a look at my routes to make sure everything is defined to begin with and that you don't have unnecessary routes.

If you don't need to communicate with your server in a RESTful way, then perhaps it's a bad idea to use resources since this will lead to internal errors.

You can check your routes using rake routes or while in development you can go to localhost:port/rails/info/routes.

At first glance, I would suspect that your path is actually play_game1_path(@game1), with the action first.

You are using resources :game1 which gives you a seven methods: index, new, create, show, edit, update, destroy. You should only specify the ones you want to use like 

resources :game1, only: [:index]

You can also make things more organized with nested routes by

resources :game1, only: [:index] do
  get "instruction"
end

resources :pages, only: [:show] do
  get "about"
end

With this setup, you will need a PagesController. The default param for show routes is :id
