Scoring

Does anyone know exactly how many points you get for the various bonuses? I have noticed a bunch of things you get bonuses for but the numbers flash so quick I don't kow what each thing is worth. The bonuses I know are:
leftover bombs
leftover scarabs
wheels
empty boards
cracked stones (do they count if they are only cracked or do you need to blow them up?)

Also, if you already have a scarab, do you get points for 3 in a row of that color?

Thanks :)
