Q*Bert is an arcade game with an age of about 40 years. It was very popular and the highest score was reached the next year after its release, although it was beaten a few years later.
The purpose of the game is to turn the cubes from one color into another. To do this, you control Q*Bert who must jump on the cubes while also paying attention to his enemies. If they catch him, it's game over.
This game used to be played on large arcade machines, but here we have the smallest possible version: it can fit in your wallet! Its measurements are 3.25 x 2 x 0.4 inches, almost as much as a bank card.
The screen is small as well, but makes use of all the colors, the original sound effects and control buttons have also been added to this pocket game. You don't need to worry about your gameplay because the micro USB cable will recharge its battery.
The sound can be turned on or off, depending on your preferences or circumstances. Make sure to also turn the device off when you're done playing, to preserve the battery.
