The iPhone is one of the world’s most popular gaming gadgets, but if you want to take it to the next level, you’ll need a controller. Amazon has the Backbone One Mobile Gaming Controller for $70 with a free month of Xbox Game Pass Ultimate included, a $30 discount off the MSRP.

You may play any controller-supported game when you insert your iPhone into the Backbone One Controller (iPhone 6s or later). It has a dedicated button for launching the Xbox Cloud Gaming online app, but you’ll need to remove your iPhone from its cover to put it correctly in the controller.

According to Backbone, you’ll need to request an adaptor for “a better experience” on iPhone 13 Pro and iPhone 13 Pro Max models, but it should function fine on all other versions. The controller includes a 3.5mm headphone jack as well as a Lightning connection for charging while playing. We haven’t tested the Backbone One controller, but it has 4.5 stars and over 3,000 ratings on Amazon.
