in order to cover the rest of the numbers. but you would have to then make a field, horn bet, etc. For example, in a regular craps game you could have place bets on the 5, 6, and 8. This is advantageous IMO since you don't have to make what I call 'extra bets' like you do in regular craps to cover every single number. I'm not sure why they decided to switch but I'm guessing it's because of a bigger 'house advantage.' In my opinion there is one aspect about crapless craps that could offer an advantage to a consistent shooter though and that is the ability to put place bets on every single number.
Just wanted to say that my city has a crapless craps table.
