Yakuza 3 Remastered

This is how I did it by only playing Cho-han, since it's very easy to play. I promise this is really easy and shouldn't take too long, despite the length of this guide. First, there is a bit of setup involved:

1. Complete substory #62 - Return to the Dragon Palace to unlock the Dragon Palace, which is where you'll find the Gambling Hall.
2. (optional)Reach Chapter 12. In earlier chapters you won't be allowed to bet as much, so it it'll take more rounds and you won't have enough cheat items (explained below) to last. Still, this isn't a deal breaker. You'll still be able to do it.
3. (optional)Get Kamurocho locker key #27 and Ryukyu key #15 to obtain 2 lopsided cigarettes. These will just make it a bit quicker. CyricZ from GameFAQs shows where to find all Kamurocho keys here and Ryukyu keys here.
4. Go to the Cho-han table and play through 30 rounds, just betting 1 each time. The rounds go by fast. Just pick even or odd and ignore the extra bets you will be offered periodically. Being in Chapter 12 and playing 30 rounds total will raise your maximum bet to the highest level - 1,000. If you've only reached Chapter 6, just play 10 rounds to reach the maximum bet of 500. If you've reached Chapter 7, play 20 rounds to reach the maximum of 800.
5. Make sure you have at least 1,000 wooden tags (slightly more is better, so you can still bet max even if you lose a few chips). You can buy less if your maximum bet is lower.
6. Save the game at the batting center around the block in case you lose and need to reload.

Now you're ready to play. Sit down at the table and press Y to select a lopsided cigarette if you have them. This will make more players bet on one side or the other. It seems to take one or two rounds to take effect, at least for me. If you don't have the cigarettes, no worries. Just keep betting one tag until you see the majority of players betting on one side, then pick the opposite side and bet 1,000 (or your max). This will maximize your winnings.

If you win, go save the game and repeat the last paragraph until you've won a total of 3,000 tags and the achievement pops. It only took me 2 wins, but if you're betting less then it'll require more. If you lose, press , Return to Title, reload and try again.

Remember when you're done to cash in your tags for plates that you can sell for money unless you want to keep them to play other games.
