Apensar (aka Wordie) is a "brain trainer" mobile game, developed by ICO Group in 2013 (now known as The Fastmind).

Gameplay consists of finding the common word between four images to reach the next level.

To pass each level and receive coins, the user must guess the word in common between four images.

If they are unsure, they can ask their contacts through social media (Facebook, Twitter, Instagram, and WhatsApp), text message, email, or pay for clues with coins.

The app currently has over 20,000,000 downloads worldwide, and each player remains active, on average, for 12 minutes a day.
