'''Stacking for tetrises''' is a useful skill in games that reward back-to-back Tetrises, or do not reward T-spins. A Tetris Line Clear is [[Line clear#Tetris|four lines cleared]] with one I [[tetromino]]. This is typically done by creating and building around an ''open column'', or a straight hole in a the stack, in order to make many consecutive Tetrises. Modes or games with emphasis on time attack have a long line clear delay, which means not clearing a Tetris wastes time.
 
 
This article will deal with the the skill of stacking for many consecutive tetrises. It will be biased towards SRS/guideline games and will mostly apply towards slow [[Drop#Gravity|gravity]]. It is a work in progress. Stacking for tetris is a useful skill in games that reward Back-to-Back 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 [http://www.tetrisconcept.com/forum/viewtopic.php?t=445] for in-depth discussion.
 
Advanced techniques must be learnt through experience, and cannot be feasibly taught.

*Stack flat, but not too flat, to allow for S and Z tetrominoes. Having a flat field will allow a player to rotate less, which saves time. A player will also have more placement opportunities. The even field will allow a player to think less which results in faster reaction times. Also, stacking flat will also mean keeping middle columns lower to the ground, lessening the risk of a [[Top out#Loss condition|block-out]].
 
*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 movements because they will move a smaller distance.

*Try not to build empty columns greater than 2 cells deep, as this will require an I tetromino that can be better used to tetris. 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.

*If [[hold piece]] option is available, make sure to keep an I in reserve to compensate for inconsistent stacking. Sometimes, a player is forced to create 3 cell deep empty columns that can only be fixed by an I tetromino. However, don't fall into the trap of stubbornly saving the I piece if doing so prevents you from stacking optimally.

*Don't waste an I if another tetromino fits better. Use an I when stacking only to avoid future complications or at the beginning of a game. Don't forget that an I can be placed anywhere on the field due to its vertical orientation.

*In singleplayer, try not to tetris if an I tetromino is not in reserve. Hold the I, stack more, and wait for the next I to come. Doing so will give a player more room for inconsistent stacking. Try not to tetris often from switching an I out of the hold box because it wastes a frame.

Stacking for tetrises is a useful skill in games that reward back-to-back Tetrises, or do not reward T-spins. A Tetris Line Clear is four lines cleared with one I tetromino. This is typically done by creating and building around an open column, or a straight hole in a the stack, in order to make many consecutive Tetrises. Modes or games with emphasis on time attack have a long line clear delay, which means not clearing a Tetris wastes time.

Basics

  • Stack flat, but not too flat, to allow for S and Z tetrominoes. Having a flat field will allow a player to rotate less, which saves time. A player will also have more placement opportunities. The even field will allow a player to think less which results in faster reaction times. Also, stacking flat will also mean keeping middle columns lower to the ground, lessening the risk of a block-out.
  • 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 movements because they will move a smaller distance.
  • Try not to build empty columns greater than 2 cells deep, as this will require an I tetromino that can be better used to tetris. 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.
  • If hold piece option is available, make sure to keep an I in reserve to compensate for inconsistent stacking. Sometimes, a player is forced to create 3 cell deep empty columns that can only be fixed by an I tetromino. However, don't fall into the trap of stubbornly saving the I piece if doing so prevents you from stacking optimally.
  • Don't waste an I if another tetromino fits better. Use an I when stacking only to avoid future complications or at the beginning of a game. Don't forget that an I can be placed anywhere on the field due to its vertical orientation.
  • In single-player, try not to tetris if an I tetromino is not in reserve. Hold the I, stack more, and wait for the next I to come. Doing so will give a player more room for inconsistent stacking. Try not to tetris often from switching an I out of the hold box because it wastes a frame.
  • Avoid situations that force a player to soft drop. At the beginning of a game, avoid situations that force a player to soft drop more than once.

Much must be learned 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.
