If you enjoy puzzle games, you might want to take a crack at homebrew developer Arber' Sabes Contar (Can you tell?) Triangle Edition for the PSP. The premise of the game is simple, count how many triangles are in an image presented on the screen and select the best answer from the options given.

The game is in Spanish, so here's a little help to get you started. The menu is controlled using the D-pad. Press the X button to select an option and the O button to go back. According to Google Translate, the first three choices on the menu mean New Items, Test, and Help. The fourth choice, Extras, is self-explanatory.

When you get to the game proper, simply choose the correct answer using the buttons. Players who don't speak Spanish shouldn't have too much of a problem with the controls since the developer thoughtfully included a visual representation of which button to press beside each selection.

If you're interested in trying out this application, be sure to go over the documentation included with the program for the installation instructions.
