The parents' guide to what's in this app.

Ease of Play

All actions are performed by tapping the screen, and difficulty ramps up at a steady, even pace.


Combat is the central focus, but violence is bloodless and characters vanish instead of die.


To collect in-game powers, players need QR codes that come from purchasing real-world Lego toys. Without this, play is possible but basic.

What parents need to know

Parents need to know that Lego Nexo Knights: Merlock 2.0 is a themed action-adventure game with cartoony, combat-centric gameplay. Based on the TV show, it frequently encourages players to purchase real-world Lego toys to improve their in-game experience and is heavily dependent on a user's familiarity with the show. Note that there's a mismatch in the iTunes store between the game's rating (age 9 and up) and its age recommendation (age 5–11).

What's it about?

LEGO NEXO KNIGHTS: MERLOK 2.0 is set in a futuristic/medieval kingdom that's under fire from an evil court jester called Jestro. Hoping to save the kingdom from Jestro and his army of lava monsters, a holographic wizard called Merlock 2.0 trains a team of recent graduates from the Knights Academy. After a brief introduction to the story, players are taught how to fight and use special attacks by tapping or tap-holding on the screen. Winning battles earns players coins, which they can use to upgrade equipment and skills, and players can unlock further skills by using the iPad's built-in camera to scan codes on real-world Lego products.

Is it any good?

Though it's amusing, especially for fans of the show, kids who don't watch or have the toys may be disappointed. Players who haven't seen the show are likely to be confused from the get-go, as it tosses you into combat and gets you to collect a group of Knights without really understanding why. A few minutes in, you're introduced to the game's scanning functionality, where you're shown how to scan QR codes from real-world Lego products (toys, TV shows, books, and websites). Though kids will probably enjoy collecting codes, it's clearly meant to make kids beg their parents to buy them more Lego products. Granted, Lego's website will be trickling codes out, and kids can also get them by watching the TV show, but kids who collect the toys will have more codes -- and more fun with the game. On the up side, there's a good amount of fun to be had for free: Graphics are bright and colorful, dialogue is amusing, and the storytelling videos between combat sequences offer a good dose of the Lego charm. Overall, for younger kids it's a decent way to spend a few hours; however, kids older than 12 might be bored with its simple, repetitive gameplay.
