Within VR (formely VRSE)
The name may have changed but Chris Milk's app is still one of the best ways to get a slice of cinematic virtual reality. There's short movies, documentaries and comedy from the likes of the New York Times and Saturday Night Live. Grab a pair of headphones as well to complete the fully immersive experience.
Oceans have been done plenty of times in VR. Caves? Not so much. VR Cave takes care of that and, while it's little short, you still get to dive into spelunking without the dirt and claustrophobia. It's also a very detailed exploration of a cave that will have you wishing it won't end. Just don't watch the horror movie The Descent before playing.

VR Crossy Road
Mobile hit Crossy Road makes the leap to VR with impressive results. The basic mechanics of the game lend themselves well to virtual reality, as you hop across a sequence of roads and try to avoid getting splattered. If you've ever played Frogger, you'll know what to expect.
A favourite of Cardboard users, Hidden Temple takes a point-and-click type puzzle adventure and brings it to mobile VR. It's all controlled by your gaze (i.e. turning your head) as you look carefully for items in an ancient temple. Plus the graphics are superb for a Cardboard VR game.
Minos Starfighter VR
Minos is a first-person space shooter best enjoyed while sat in a swivel chair (but standing is fine too). You'll be blasting other ships as your enemies become progressively more difficult, but be sure to take in the impressive visuals too. This is a decent demonstration of how good VR can be even on cheap headsets like Cardboard.

Adventure Time: I See Ooo VR
A bit pricey for just two VR mini games but Cartoon Network has also added a puzzle to the mix. One game has you gliding through Ooo, another snowball fighting against penguins, to rescue Adventure Time characters like Jake, BMO and Princess Bubblegum.
Bohemian Rhapsody Experience
Love Queen? The Bohemian Rhapsody Experience takes you on a journey through frontman Freddie Mercury's subconscious mind and recreates the sensation of being onstage with the band, complete with visual and audio components that respond to your movements.
Fulldive is a virtual reality platform that allows you to browse and view 3D and 360 photos and videos, and also browse the internet. There's quite a lot you can do including taking your own VR photos, stream 360 YouTube videos and compatibility for Netflix, Hulu and Roku are all on the way.
Wizard Academy VR
Wizard Academy is a bunch of action and learning games that launches you into a magical land where you can navigate around a village to discover the various educational and ridiculously fun challenges. A 'controller' is needed for VR which can be bought here, however in true Cardboard fashion, you can make one yourself by downloading a free kit.
Google Arts & Culture
Google has produced some solid VR and 360-degree content, and Google Arts & Culture is another we think is worth checking out. You can explore artwork, artifacts and more from over 850 museums, archives, and organizations worldwide that have partnered with Google Cultural Institute to bring their collections and stories online. There are even options to zoom in for a closer look and factual tidbits if you want to learn more.
