The core logic of Number generation and comparison can be greatly simplified by using For /L and For /F loops in conjunction with indexed arrays:
@Echo Off
Setlocal EnableDelayedExpansion
:Gameloop
CLS
Set /A R1=!Random! %%9+1,R2=!Random! %%9+1,R3=!Random! %%9+1
Echo(
For /L %%i in (1 1 3)Do (
Echo([E]xit or Pick Number %%i [0-9]:
For /F "Delims=" %%G in ('Choice /N /C:0123456789E')Do (
If "%%G" == "E" (Endlocal & Exit /B)
Set "N%%i=%%G"
<Nul Set /P "=[%%G] "
)
)
Echo(Numbers Rolled:
Echo( [!R1!][!R2!][!R3!]
Set "Matches=0"
For /L %%i in (1 1 3)Do (
If !R%%i! EQU !N%%i! (
Set "M%%i=!R%%i!"
Set /A Matches+=1
) Else Set "M%%i=-"
)
Set /A Score+=( Matches * 100 ) * Matches + 0
Echo(Numbers Matched: [!M1!][!M2!][!M3!]
Echo(Score !Score!

Goto :Gameloop
'rolled' numbers get assigned to R#
'Selected' numbers ~ to N#
M# Array is used to Display Matched characters.
