Z and S blocks do not only compliment the L and J blocks, but also the T-block (named so because it resembles the capital 'T'). Just be aware how you stack Z and S blocks on the L and J blocks - how you arrange the meeting between these four blocks is critical in your ability to prepare either the Tetris or plain line completions. The single block that just out can be saddled with a Z or S block to create some semblance of a solid structure. When in doubt about L and J blocks, seek to press them down so they cover 2-block and 3-block wide gaps. They are certainly helpful in cases where you need to fill up the 2-block high spaces left from placing Z, S, and O blocks. Using just one type of L (or J) block, you can complete 2 to 3 lines each time.

L and J blocks are complimentary only to another L or J block (but not to each other). Most of the time, the L-block or J-block is used to fill in a gap (2-blocks high) where the outrigger block won't get in the way. The L-block (named for its resemblance to the capital 'L') is the opposite of the J-block (like the L-block but takes after the capital 'J'). You rarely get a chance to have such serendipity during a match, hence your key strategy is to flatten everything as quickly and as (time) efficently as possible. Similarly, a J, S, and L block can create a similar set-up, although this is all theoretical. Using one J, Z, and L block each, you can create a 4x3 structure three blocks high that can serve to complete lines down the road. The Z-block (so named for its resemblance to the capital 'Z') and its complementary S block are essentially complimentary blocks to the L and J blocks. If you pile on too many O-blocks, you create a very difficult column to pare down. If you are in a hurry, drop it in a 2-block wide space. O-blocks are ultimately good to fill in and pave over the 2-block "space" of a J or L block on its side. Beware of stacking too many O-blocks vertically, as you may not get the I-blocks needed to fill in the spaces next to an unexpected column. L, J, and I blocks complement the O-block, depending if you have the room to fit them in perfectly. The O-block (named so because it resembles a capital 'O') is a block you don't have to swivel or rotate. This tends to create a Tetris Canyon, and gives you enough space in the middle to correct any potential mistakes down the road. The best "quick" place to put an I-block (if you're not thinking too far ahead) would be to the sides. Hence, it's always a good idea to drop your blocks so more tetrads can be used to "pave them over" (creating a smooth block for line completion). I-blocks are the only Tetrad that can fill in a hole that is three blocks or higher.

It's a good piece to put horizontally if you have nothing else better to do, but it's more handy to store it for a future Tetris when you have the chance to (in the Hold function).

The I-block (named since it resembles a capital 'I') is the block that you would use to complete the Tetris. If you allow the falling blocks (tetriminos or tetrads) to reach the upper perimeter of the playfield, your game is over (and you lose the match).ĭepending on the mode, your goal may be to complete a certain number of lines, or simply to score as many points as possible (this will be adherent to the Tetris Friends rules) to shove penalty lines into your opponent's play field. The basics have always and will be the completion of a line (row) of ten blocks from one side of the playing field (the matrix) to the other.
