Mobile phones have undergone major advancement in recent years and people can do most things – including working, watching films and gaming – on them now. Gaming is particularly popular, both basic card games at mobile casino and those with eye-candy visuals like The Room Two.

Top 5 smartphones for gaming in 2015

LG G3 (£479) This is not the cheapest smartphone, but it has gaming advantages. A 5.5-inch screen with 1440 x 2560 resolution means visuals on classy puzzle games like The Room Two look great, while you have the option of upgrading the OS to Android Lollipop 5.0. There is also storage space of 16 GB, for keeping loads of puzzle, RPG and casino games on it.

Sony Xperia Z3 Compact (£349) One of the best things about this is the way its small, thin body (12.3 x 64.9 x 8.6 mm and 129g) means you can hold it all day playing online poker or The Monument Valley without worrying about arm strain. The 4.6 inch screen might put off some, but it’s HD and it also comes with an Adreno 330 graphics chip.

HTC One (M8) (£550) This offers new features like a slot for microSD cards, and is a superb gaming phone. A 5-inch Super LCD screen with 1080 x 1920 resolution is one of them; while a quad core Krait 400 2.3 GHz processor and Adreno 330 graphics chip are two more selling points. The major negative is the heavy price.

Samsung Galaxy Note 4 (£599) This is both expensive and rather bulky (176g), but you get 5.7 inches of screen with 1440 x 2560-pixel resolution, plus a quad-core Krait processor and Adreno 420 graphics chip. Thus everything from slots to Asphalt 8 looks and runs perfectly on this phone.

Google Nexus 5 (£299) For an affordable price, you get a 4.95-inch screen and resolution of 1080 x 1920 resolution here – as well as fine processors. You can also get up to 32 GB storage, so this is a very solid gaming phone at a cost-effective price. These are all good gaming smartphones, but the Google Nexus 5 gives you what you need at a good price.
