Happy New Year to the RIO community !
Here's a script for an easier RNG (it's always updating every at the tip of your mouse pointer) :
> install Autohotkey first, at autohotkey.com

SetBatchLines, -1
lastNumTick := A_TickCount
Random, randNum, 1, 100
SetTimer, UpdateRandomNumber, 1

UpdateRandomNumber:
If (ATickCount > lastNumTick+3000) {
Random, randNum, 1, 100
lastNumTick := ATickCount
}
ToolTip, %randNum%
Return

ESC::ExitApp
v285msg=0
showwalkthru=0
guix=0
guiy=353
lasttab=
filename=RNG.ahk.ahk
isreloading=0
version=2.85
win_ver=10.0.10586

(can't remember where exactly I found it; probably on the Autohotkey site.)

HTH.
