Seed data contaminating my test cases

Hi folks - I have the following test:

public function test_can_fuzzy_search_games()
    {
        $game = factory(game::class)->create([
            'name' => 'DS Game 1'
        ]);   
        $game = factory(game::class)->create([
            'name' => 'DS Game 2'
        ]);   
        $game = factory(game::class)->create([
            'name' => 'DS Game 3'
        ]);  
        $game = factory(game::class)->create([
            'name' => 'Other game'
        ]);  

        $foundgames = game::fuzzyFindgame('DS Game');
        $this->assertEquals($foundgames->count(), 3);

        $foundgames = game::fuzzyFindgame('DS Game 1');
        $this->assertEquals($foundgames->count(), 1);

        $foundgames = game::fuzzyFindgame('fjriejg');
        $this->assertEquals($foundgames->count(), 0);

        $foundgames = game::fuzzyFindgame('ga');
        $this->assertEquals($foundgames->count(), 4);
    }

I am generating 4 games and running the tests. All are passing except the last one to check there are 4 games found for a particular search term. It is returning 6, and I have found that this is including 2 games that I have included as seed data. Is there any way to discount this seed data reliably? Or do I need to start with database tables each time?

Thanks. DS
