Summertime, the sun is shining, you’re lying in the sand and the days seem almost endless: sounds like a good time to give Brain Out a try, with its little puzzles that challenge your mind--as well as your self-restraint when it comes to not hurling your smartphone into the sea.

Warning: the solutions to the app’s puzzles don’t follow conventional logic, so you’ll need to stretch your creativity.

What we liked:

—the playful, silly side of the game

—how the developers try to tease out and capture your intelligence

What we liked less:

—when you thought you’d get a break by sticking your kid in a deckchair with this app, but now they’re going more insane than before

—when your kids get into a screaming match because one of them called the other one a “loser” for failing to solve one of these damn puzzles

—just, generally, the degrading family vibes on this vacation thanks to this app

—on a more serious note: too many adverts!

The app can be found and .
