Premise
This article will deal with the the skill of stacking for many consecutive tetrises. It will be biased towards SRS and guideline games. It is a work in progress. Stacking for tetris is a useful skill in games that reward B2B tetrises, or do not reward t-spins. There is an argument to be made that pure tetrising is more elegant than other methods that involves lesser clears or t-spins. see [1] for in-depth discussion.
Advanced techniques must be learnt through experience, and cannot be feasibly taught.
Basics
- Stack flat, but not too flat, to allow for S and Z tetrominoes. Having a flat field will allow you to rotate less and save time.
- In SRS, leave the column on the far right open to tetris in, as pieces are biased towards the left. You will save a few translations because they will move a smaller distance.
- Try not to build empty columns greater than 2 blocks deep, as this will require an I block that can be used for tetrising. However, a Tetris requires 10 pieces, so for roughly every 2nd tetris, you have an I block to spare if you are using the 7-bag randomizer.
Much must be learnt from experience, and you will quickly see what pieces when placed in certain positions compromise your future stacking. When this happens, stop and examine the playfield, and determine the best position. Analyze your playing to better yourself.
Situational
- Use a T to convert an S/Z field position into a Z/S.
- Eliminate step pyramid structures with a T. Avoid fixing such situations with S and Z, which often leads to castle structures.
- Eliminate castle strutures with a T depending on your preview.
- Avoid placing a J upright towards the left wall if you don't expect another J to appear soon. The same idea applies to L tetrominoes, either at a wall or at the edge.
