General technique

Tetris is an abstract games with some elements of luck and a range of goals depending on the variant, making it difficult to formulate definite strategies and tactics. In many variants, a player's success lies in how accurately, efficiently, and quickly he or she can preform. This remains especially true for matches against an opponent. Some variants remove the time element, making speed less important.

Some techniques are common in many experts. Remember that beginner players will naturally take the route easiest to learn, which may not always be the best. In some cases, a player may need more than just one sitting to learn how to do something a different way. An important trait of a successful player is that he is able to change his ways and take the time to learn something better.

• Stacking for tetrises. Almost all authentic games reward the player for making tetrises. In most cases, clearing a single in order to move on to the next tetris is more efficient than building the single to a double or triple. Although, in games with line clear delay, it's of course faster to clear one triple rather than clearing three singles to get to that upcoming tetris.
• Clearing garbage. In a match against another player, the goal is to prevent yourself from topping out and to make your opponent top out instead. Remember to look down and see what garbage you have to deal with. In a lot of cases, it is more beneficial remove this garbage than trying to send more to your opponent.
