Simple Block Randomizer
by Dev-Sebi
Simple Block Randomizer makes each block placement pick a random enabled hotbar slot, so a player building with several variants does not have to scroll between them.
What it does
Players choose which hotbar slots take part, and every right click places a block from one of them chosen at random. The selection is made when the slot is picked, and the mod only changes the slot selected just before normal vanilla placement runs, so placement rules are unchanged and it never places a block that vanilla would refuse.
The settings screen shows the nine hotbar slots live, with buttons to enable or disable them quickly. A small marker in the top-left corner displays the current mode. Fly can be toggled with a single key without opening a menu, and the settings open straight from the Mod Menu list. Both keys can be rebound under Options, Controls, Block Randomizer, and the settings persist across restarts.
The mod is a client-side only Fabric mod for 26.2, with build 1.0.1 for 26.2 as the latest file, first published on 2026-07-31 and last updated on 2026-08-08. It is released under the MIT License and is not open source. Only the client needs it, so servers run without it.

Use cases
Building walls from mixed blocks
Stone walls built from four different variants can be laid in one pass, since every click draws from the enabled slots.
Who it’s for: Builders working on decorative structures who want mixed block patterns without manual slot switching. The settings and mode marker suit players who change the selection often.

What the author says
Building a stone wall out of four different variants usually means scrolling your hotbar between every single click. Block Randomizer does the scrolling for you: enable the slots you want to build with, and every placement picks one of them at random. Client-side only. Works on any server, no server install needed.
