@blackvenomm666 , in each section you could use the "unset" on one line to shorten the code.
example: unset %amount %people %lottery %winner ...

Hmmmm I must have done something wrong, i couldn't get it to work at all for me

alias start {
  set %chan $$?="What channel will the lottery game be played in?"
  set %master $$?="Who will run the lottery game? (The user, not the bot. This user will be the only one who can add powerusers.)
}

  tokenize 32 $strip($1-)

    }
    elseif (%points [ $+ [ $nick ] ]) {

    }
  }

^^^^this version will strip colors so people dont have to turn them off. And also groups your on text events

There's one section of your code that you can shorten a lot more using:

    tokenize 32 %people
    if ($1-5 != $null) {
     var %x = 1
     while (%x <= 5) {
     inc %points [ $+ [ $+($,%x) ] ]
     inc %x
    }
    unset %amount %people %lottery
    msg # the lottery was ended by $nick $+ !
  }
