塔防，英文Tower Defence，是说你属于防守一方，敌人不停的进攻你，而你需要不停的制造战士来阻止对方的入侵，不过对方不会攻击我方成员，他们的目的是我方总部，一旦攻入总部就输了. 植物大战僵尸玩过吧?那就是标准的塔防类的游戏.

塔防不是指一个游戏，而是泛指一些靠自己制造防御武器抵挡敌人进攻的游戏。三好说的是他的三个好处。

it sounds like some 'tower defense' computer game genre which is quite popular. if you were to ask me, i will interpret as '3 good points of tower defense games'

塔は 塔です、防は 守るの意味です。塔防类游戏は ひとつの類の塔を守るのゲーム かもしれません。 三好は 三番号かもしれない。好と号は 中国語なかに まったく 同じ 読み方ですから。

塔防类游戏 is actually called "Tower Defense Game" in English. It is a type of strategy game where the player needs to defend his territory from the incoming enemies that usually would attack in multiple waves. The player will need to place his defense elements strategically according to the terrain of his territory in a way to outlast the enemy. "塔防类游戏三好" means the 3 good points of Tower Defense game (you can see it as "【塔防类游戏】的【三】个【好】处")~ Hope this helps!!
