IF multiple conditions PowerShell

Why does it always returns me "Non valid input..."?

$var = Read-Host -prompt "Insert a number from 1 to 6"
    
if (($var -ne 1)-or ($var -ne 2)-or ($var -ne 3)-or ($var -ne 4)-or ($var -ne 5)-or ($var -ne 6)){
Write-Host "Non valid input..."
pause; exit
} else {
Write-Host "OK."
pause; exit
}
