Suggest we have new names for 4D, Toto, Big sweep, S’pore Pool. The existing ones can be interpreted to have some unlucky and unpleasant meaning:-
4D - 4 sounds like die in hokkien, cantonese & mandarin. D can mean D day. But for some people, die, die also must buy.
Toto - 'To' once, sounds like collapse or fall in hokkien but if you ‘to’ once a week, it does not generate enough revenue for the banker. So it’s Toto. Now you know why they have 2 draws a week.
Big sweep - sweep relates to broom and brooms are related to bad luck among some chinese.
Singapore pool - 'pool' sounds like something vulgar in teochew.
