For this achievement you'll need to get an A rank on each effect mode. Those modes who offer endless mode do not need to be completed in both regular and endless mode; one it's just enough (that will also make our lives easier).
There are a few modes pretty tough, so you'll need a lot of practice and tons of patience unless you are already a pro at Tetris. You don't really need any advanced techniques to pull this off, but you need to be familiar with how scoring works and use often methods like t-spin, back-to-back or keeping a high combo (mainly for the high-scoring modes).
Be sure to understand each mode rules, it can make a big difference. Eg:
- in Purify you need to clear the dark blocks, and that should be your priority.
- in Countdown, getting a tetris or back-to-backs when pieces fall will give you bonus points.
Also note that, unlike the rest of the game, several modes are time constraint.
Marathon, Countdown and Mystery allow playing in endless mode. As far as I know, there is no penalty for this, so it makes it slightly easier to achieve the required score. Nonetheless, it's recommended to start with a high initial speed level (9-10 worked well for me). You can configure these settings just before starting the game. Other modes offer some configuration as well, but I didn't need to touch them. Feel free to play around if you are struggling with any of those modes.
Combo, All clear and Target are mainly about memorizing. Learn the patterns and you'll get the goal score even with a few mistakes.

* Keep in mind that some scores are indicative based on what I got (I put my score in brackets, so that you know that's a guaranteed A). However, it's possible that you can get an A grade with less points or fall a bit short.
