Where can I read Kaiji?

I love the Kaiji series and it's one of the few things I like enough to read the manga. However, I get to chapter 23 of the third volume, where Kaiji is playing restricted rock paper scissors, and I cannot find the next chapter. It jumps to the fourth volume and I have no idea what's going on. Whenever I try to google for chapter 24, I get Kaiji playing the dice game in the underground work camp, which skips the rest of the cruise ship as well as the human derby, ecard, and the tissue box raffle. Even when I specify chapter 24 volume 3 Tobaku Mokushiroku, I always get the work camp game.

Or is it okay to skip it? Is there anything in the manga from the beginning to the work camp that isn't covered by the anime? I thought there were a few gambles or plots that weren't in the anime, but I don't know. I definitely don't want to skip anything that has mikoko in it though because she was barely in the anime and I like her a lot.

If I can skip the first part, can I please have a link to the start of the second part? Even though I know how the work camp part goes, I don't want to start in the middle of it.
