You just need to learn how the I piece rotates. Its basic rotation, taken from Sega's 1988 Tetris, is this:
- horizontal_I.png (382 Bytes) Viewed 141 times
- vertical_I.png (397 Bytes) Viewed 141 times
Note that there's only two states, and that its center of rotation is the second mino from the top or right. This means it has a right-side bias. It's rather inflexible by default, but Tromi has a system of wallkicks that's honestly too complicated to explain for the purposes of this question but I promise it makes sense lol.
In any case, in the following two situations and with Tromi's wallkicks, this is the maximum elevation allowed for the I piece to be rotated into a right-side well and a left-side well, respectively:
- can_kick_up.png (578 Bytes) Viewed 141 times
In this first situation the very bottom of the vertical I piece would be blocked by the stack, but in Tromi when that particular blockage occurs it will attempt to kick the piece one space up, which means it would successfully rotate and you could tap right and it would fall into the right well.
- can_kick_left.png (539 Bytes) Viewed 141 times
In this second situation the third mino from the top of the vertical I would be blocked by the stack, which in Tromi takes precedence in wallkick considerations over the bottom mino being blocked, and it will attempt to shift the piece one space left instead. Here it would successfully rotate, after which you could go one space left and get it into the left well.
At high enough gravity you would be able to simply hold the left or right direction to make it autoshift into one of those positions, after which you could tap rotate and it would appear to just rotate into the well. It takes practice to get this kind of finesse down.
Most importantly, in case you don't know already, you can hold a rotate button down before a piece spawns and it will spawn in that orientation. In the two cases above this would work fine as the center part of the stack is perfectly flat so it wouldn't get caught in anything while moving, but in situations where it would get caught you might want to keep the I piece in its horizontal orientation while getting it over to one side or the other, THEN rotate it into the well.
I hope this isn't like super overwhelming lol. Maybe a more helpful thing to do is to go into the training mode where you have infinite lock delay and just rotate pieces around, see what works and what doesn't.
