It’s time to go out with the old and in with the new. Well, only if you need to free up space on your phone or tablet, we suppose. If you’ve got plenty of memory left, then by all means keep those favorites and even those mobile games you haven’t played in a while but have been meaning to revisit.

You can still try something new as well, and we believe we’ve narrowed down the myriad choices thrown at you by the app stores to the four most promising mobile games of the week. We’re cool like dat (h/t Digable Planets).

The Room: Old Sins

The Room: Old Sins

If there are mobile gamers out there who don’t like The Room series, we’d like to meet them and ask them why. Fireproof Games has cracked the code on atmospheric puzzlers, tossing in some narrative goodness for good measure. Reviewers are already raving about Old Sins, so there’s no reason not to get it if you liked the previous games in the franchise.

Tactical Monsters Rumble Arena

Tactical Monsters Rumble Arena

Sure, you’ve seen turn-based battles on a hex grid before, probably dozens of times. But have you seen them with Frankenstein, Medusa, The Mummy, Bigfoot and other monsters of legend? We submit that you have probably not, and thus you want to check this game out to rectify that.

Meteorfall: Journey

Meteorfall: Journey

Who says every card game on mobile has to be a CCG? Not us, certainly, and not the developers of Meteorfall: Journey (with a bonus ‘s’ on Android because why not?). This “deck-building roguelike” challenges you to pick one of four adventurers and then, you know, adventure. With monsters, bosses and all that good stuff.

Thumper: Pocket Edition

Thumper: Pocket Edition

We’re not entirely sure what a “rhythm violence” game, but the App Store recognizes it as such, so that works for us. With graphics that look like ’70s rock band cover art come to life, you control your space beetle and try to avoid being destroyed by a giant mechanical head. We wish we were creative enough to have made up that description.
