Riiverse's logo.
Riiverse was a Miiverse clone created some time in late 2017 by users known as NintenBlox and Matrix. It was shut down, and as a result a user known as FunnyBone created a Miiverse replacement known as Wiiverse. Riiverse was brought back up in early 2020 under the domain rii.uiiverse.xyz, and was linked to on Uiiverse. This version of Riiverse shut down on April 22, 2020.
