RJDJ is gone, but RJDJ Dimensions is still around

So, to mark the last day that RJDJ was on the app store (it's gone now), the new app of the week is RJDJ's Dimensions game, which is free too.

And if anyone's noticed weird price fluctuations on the app of the week widget please let me know as one reader has experienced some very strange behaviour with it.
