Error: Call to undefined method stdClass::save()

I get a error when trying to upload a image, this generates the error:

public function updatelogo(Request $request)
{
  $game_id = $request->input('game');
  $games = DB::table('games')->where('id', $game_id)->first();

  if($request->hasFile('logo')){
        $logo = $request->file('logo');
        $filename = time() . '.' . $logo->getClientOriginalExtension();
        Image::make($logo)->resize(50, 50)->save( public_path('/images/games/' . $filename ) );


        $games->logourl = $filename;
        $games->save();
        return redirect()->back()->with("status", "Succesfully edited!");
      }
}

This is the frontend:

 <form  role="form" enctype="multipart/form-data"  action="{{ url('/admin/sitesettings/games/edit/logo') }}" method="POST">
                           <input type="hidden" name="_token" value="{{ csrf_token() }}">
                           <div class="form-group">
                               <label for="logo" class="col-md-4 control-label">Logo</label>
                               <small>Upload a logo for the game:</small>
                               <select name="game" id="game">
                                 @foreach($games as $game)
                                  <option value="{{$game->id}}">{{$game->id}}</option>
                                 @endforeach
                                </select>
                               <div>
                                   <input id="logo" type="file" class="form-control" name="logo">
                               </div>
                           </div>
                       </div>
                         <button type="submit" class="btn btn-primary">Save changes</button>
                     </form>

Thanks in advance!
