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

Educational Value

Kids can learn about finding words among collections of letters. As kids experiment combining letters, they'll practice finding patterns among words. Premade multi-letter bubbles point to common letter combinations and highlight important phonemes. Kids will need some critical thinking and good puzzle-solving skills to see words through all the many bubbles, and they'll feel a great sense of accomplishment, as they are entirely in charge of finding and building words. Though it may have some mechanics that don't work well for all kids, Planet Lettra Word Building Playground is a no-penalty way for kids to create and explore words.

Ease of Play

Pretty simple, but it may take time to get used to moving the bubbles and combining without undesired results.

Violence & Scariness
Sexy Stuff

The little alien creatures sometimes make fart or burp noises.

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that Planet Lettra Word Building Playground lets kids combine bubbles with letter and letter combinations to make words. Kids are in charge with no guidelines, time limits, rules, or points to accrue on this open-ended word-building planet. Other than some premade letter combinations and a handful of preset words, there are also no prompts for forming words, so kids are pretty much on their own in finding ways to make words. Kids can play in English, Spanish, or French -- simply change the language in the settings menu on the home screen. English is also available in an Australian, American, British, or Irish accent.

What's it about?

Visit PLANET LETTRA WORD BUILDING PLAYGROUND where letter bubbles float around waiting to be combined into words. Some bubbles contain single letters, others have letter combinations, and new bubbles are constantly releasing and combining. To learn how all the features work, watch the short video tour. Kids can adjust how easily bubbles combine, feed words and letters to alien creatures, clear the bubbles to release more, and change a single-letter bubble to a different letter. Look down into the planet to review and hear the words you've made.

Is it any good?

Kids are free to experiment, combine letters, and test their word-building abilities in this fun digital letter block game. The open-ended platform allows kids full freedom to explore and empowers them to find words all on their own. Some bubbles contain letter combinations or full words, which provides a little push toward putting a word together. Overall, though, kids need a pretty solid comfort level with words to prepare a word mentally and construct it successfully. Though kids can make up words that aren't in any dictionary, it's tricky to figure out which words work and which don't. Also, alien creatures that eat the words are a cute feature, though it can be quite frustrating when a long tongue reaches out to grab a bubble as you're trying to use it. And, based on how kids adjust the bubbles' settings, they may or may not combine when desired, so kids will likely need some time to figure out how to manipulate them to avoid frustrating surprises. For kids who can navigate the functionality and have the patience to play around with the features, it's a fun and potentially educational experience.
