ジャンケンがループしない

ruby

コード ``puts "あっち向いてホイを始めます"puts "ジャンケン・・・"class JankenAcchimuite def initialize (draw ="あいこ",lose ="負け",win ="勝ち") @draw = draw @lose = lose @win = win end def janken #実装する puts "[0]グー,[1]チョキ,[2]パー" player_hand = gets.to_i program_hand = rand(3) jankens = ["グー","チョキ","パー"] puts "あなたの手:#{jankens[player_hand]},相手の手:#{jankens[program_hand]}" if player_hand == program_hand puts "#{@draw}" return true elsif (player_hand == 0 && program_hand == 2 ) ||( player_hand == 1 && program_hand == 0 )||( player_hand == 2 && program_hand == 1) puts "#{@lose}" return false elsif (player_hand == 0 && program_hand == 1 ) ||( player_hand == 1 && program_hand == 2 )||( player_hand == 2 && program_hand == 0) puts "#{@win}" return false end next_game = true while next_game next_game = janken end end def acchimuite_hoi puts "0(上)1(下)2(左)3(右)" player_direction = gets.to_i program_direction = rand(4) directions = ["上","下","左","右"] puts "あなた：#{directions[player_direction]} 相手：#{directions[program_direction]}" if player_direction == program_direction if @lose puts "#{@lose}" elsif @win puts "#{@win}" end else puts "#{@draw}" end end result1 = JankenAcchimuite.new("あいこ","あっち向いて","あっち向いて") puts result1.janken result2 = JankenAcchimuite.new("もう一度ジャンケンを行います","負けました","勝ちました") puts result2.acchimuite_hoi end 、、、 whileを使用しtrue,falseで戻しているつもりなのですが、ジャンケンがループせずにそのままあっち向いてホイに行ってしまいます。お願いします。
