You can get a taste of Civilization VI by playing your first 60 turns for free. To keep going and unlock the full game, it'll typically cost you $60, though it's on sale for $24 until October 16th to mark the iPhone launch. Since it's a resource-intensive title (with almost all of the PC version's features), you'll need an iPhone 7 or newer handset.

Meanwhile, if you'd like another way to grow your empire from the Stone Age to the modern era while on your commute, it's worth noting the game is also making its way to Nintendo Switch next month.
