The Room: Old Sins recently launched on iOS, and it's coming to Android soon. For many people, this will be their first experience with the series, and I dare say a bit of a revelation.

Fireproof's locked box puzzler is way more intricately detailed and atmospheric than most other mobile puzzlers, offering up a selection of tactile conundrums and a spooky story.

It's the kind of game you'll probably want to play through in just a couple of extended sittings. So what next?

There are a few other games on the App Store that are similar to The Room in concept or execution. Let's start with the obvious ones.

The Room

The Room series kicked off right here way back in 2012.

If The Room: Old Sins is your first The Room game, this is your natural next step. It's a different storyline to the recent game, but it retains the same core gameplay with the same obsessive focus on clockwork contraptions.

The Room still holds up beautifully today. Play it before anything else on this list.

The Room Two

The next game you should play after The Room is, quite logically, The Room Two. Its story follows on from The Room, so there's a narrative imperative to playing the games in sequence.

We wouldn't necessarily say that this is a better game than the original - there was much to be said for the original's focused 'box within a box within a box' structure - but it's certainly more varied and ambitious.

There are new kinds of boxes and new rooms in this sequel, giving you a new wider perspective on the puzzles.

The Room Three

The third game in the original The Room series probably bears the most similarity to Old Sins. It continues the story from the first two games, but it widens the scope and interconnects its various puzzle elements in a way that foreshadows the new game.

You also get sections where you need to manipulate two objects at once using two fingers, which is another element that's present in Old Sins.

Basically, if you love The Room: Old Sins, you'll love The Room Three. It's that simple.

The House of Da Vinci

How about if you've rinsed The Room series for all its worth and still want more? You could do worse than check out The House of Da Vinci.

This is easily the most direct lift from The Room, with a strikingly similar design. You might play as Leonardo Da Vinci's apprentice, but mechanically you're doing many of the same things as you did in Fireproof's game.

That means unlocking intricate contraptions and following a breadcrumb trail laid by a mysteriously absent mentor. There's even an eyeglass gizmo that lets you see hidden elements.

Forever Lost

Forever Lost has clearly been inspired by The Room, with a series of first person mechanical puzzles and a spooky atmosphere.

However, it's a little more expansive than Fireproof's games. Here you're escaping from rooms rather than trying to break into boxes.

This a game with multiple episodes, and the good news is that it improves as it goes along, with more variety and sharper presentation in episodes two and three.

Agent A: A Puzzle in Disguise

Agent A is another classy escape-the-room puzzler, with all the keys and combinations and secret compartments that suggests.

However, it ditches the spooky histrionics of The Room and its disciples in favour of a sharp, super-stylised '60s secret agent pastiche.

It also borrows liberally from the point-and-click adventure genre, which in turn provided a lot of the source material for The Room.

The Witness

Want to take your first person puzzle solving to a whole new dimension after The Room: Old Sins? The Witness is a great next step - though it's quite a big one.

The game is packed full of tactile locked box puzzles, but here those locked boxes are large structures littered over an open island that can be freely explored. Solving those conundrums involves a specific type of line-drawing puzzle, too, but it takes you in a surprising number of directions.

The Witness is a far brighter, more expansive, and more abstract first person puzzler than The Room, but it scratches a similar inquisitive itch.

Mysterious AR

The Room is notable for being an extremely tactile puzzler, with lifelike materials that respond to your touch. Mysterious AR takes that template and applies a layer of augmented reality (AR) magic to it, courtesy of Apple's ARKit.

Essentially, the locked boxes here sit on your kitchen table (or any other flat surface), and you literally move your phone around to get a new angle on the conundrum.

Is it as atmospheric or polished as The Room? Of course not, but the whole AR angle is an interesting and logical way forward.
