Looking back, we hadn't updated our list of the best tower defence games on iOS for two years prior to today.
There's a good reason for this, and it's nothing to do with negligence or laziness. Well, not entirely.
Put simply, the tower defence genre isn't anywhere near as popular as it used to be. We can count the number of notable TD releases since September 2016 on one hand.
Still, it remains a fun and mobile-friendly strategy sub genre with some downright classic games. What's more, you still see a little TD magic sprinkled across some of the popular hybrid genres of the moment.
