In Terminal Quest, the app prompts you to enter Linux commands such as "ls" (list files) and "cat" (to get file info) but uses them as part of the story.The market is filled with kits that teach children about programming by having them build a robot. This $249 system does a fantastic job of explaining complex concepts, such as the Linux command line, and turning them into a game. For example, there's a set of 15 challenges that helps you create and refine a game of Pong, and a set of three that has you build a weather station.

This delay prevents accidental power-ons, but if you don't know about the delay, you may think the device is out of juice or broken.Hack Minecraft lets you design your own custom objects for the Minecraft game, using block-based coding.

Putting together the Kano Computer Kit was extremely simple and took me and my 5-year-old son less than an hour. The right pane has a list of staff-recommended apps or other updated status messages. You build it before you program it, and it comes with a few games built in.Challenges come in sets of three or more, which help you build an increasingly complex program.

In addition, there's no clamshell that opens and closes.The $29.99 Motion Sensor Kit plugs into a USB port and allows you to create programs that react when you wave your hand over it.The keyboard is fine for small hands, but parents might find it cramped. Others invite you to perform code challenges, such as designing your own game of Pong or building your own Snake game.One of the coolest parts of the Kano experience, Story Mode is an adventure game where your character explores an 8-bit world that's meant to mirror the world inside the computer. Parents who buy this product for young children should immediately change this to Ultimate Settings, which allows kids to only visit the Kano World website, which is where some of the challenges are located. It's important to note that you need to hold down the power button for 3 seconds in order to turn on the device. For example, one challenge had me draw a Swiss flag by typing in commands to build the white cross in the middle and the red background.The computer comes set to Low Settings, which only blocks sites on your blacklist (the list is empty by default), and has SafeSearch enabled on Google and YouTube. But ultimately, it wasn't particularly exciting.The middle section has shortcut icons for nine apps at a time (you can click tabs to see more apps). The bright orange wireless keyboard, which has a built-in touchpad, is separate from the body of the computer. Overall, we had a lot of fun playing with the Pixel Kit and drawing different images on it.My favorite feature of the Kano Computer Kit, Terminal Quest is a text-based adventure that teaches children about the Linux command prompt. Several times, I had to restart a challenge or hit the button to go back several steps because the app got confused when I accidentally dropped a code block in its tab before dragging it completely onto the canvas (this could happen if a child has difficulty dragging and dropping objects). Both the instruction manual and the online tutorials are extremely well-written and do a great job of making learning fun. As you walk around a colorful map, you visit areas such as SD beach, Logic Lake and Fiberglass plains. Based on my experience using the device on and off over the course of two weeks, that estimate seems accurate.When you click on each tab, you see a list of code blocks that you drag out onto the canvas and connect together.
