Not for Primary education!
This website was used in my son’s primary school (UK - age 5-11). It taught, via one of the games, my son the below lessons:
1) An aubergine is an emoji representation for penis
2) If you mix a date with alcohol it leads to sex
3) If you make other word combinations you can make ur anus. No not the planet. Two separate words.
4) Students began using search engines to gain instructions to create the worst they could imagine.
After a short while playing it, you can create a tile with F U on it and an accompanying emoji of the middle finger.
Whilst I have no doubt that some of the other content may be educational, there can be ZERO excuse for an educational establishment to allow unsupervised use when these games allow such content to minors.
Also keep in mind, Infinite Craft when packaged as an app is rated 13+ (Apple) and 16+ (Google).
