“The wider the gap
the longer the combo,
the wider the gap,
the harder to stack”
There many kinds of combo set ups, the 2 wide, 3 wide , and the very famous 4 wide. I think 4 wide is the best strategy to use in 6p battle, also works well 2p battle. To be a good 4 wider you should know how to look ahead, use hold effectively, using the right piece and can rotate in both directions. I think stacking is the hardest part at first because you need to stack only on 6 matrix columns, but as you play and practice you wouldn’t even notice that you are getting better at stacking. I recommend that you watch 4 wide videos on youtube, it’ll help you get the idea how 4 wide works.
I learned how to 4 wide and 3 wide in nullpomino. Nullpomino is an open source and free action puzzle game that works on java platform. I highly recommend that you download the game (click here to download).
Once nullpomino is installed, Go to Option>Keyboard Setting: 1P and copy my settings. Don’t forget to hit save and exit afterwards.
This is the tetris battle keyboard settings for nullpomino.
Now to start your 4-wide practice click Start>[more…]>race modes>combo race>standard plus and copy my settings.
Here's a sample video of how the game works:
The most commonly used 4 wide start is the "I tetrimino".
If you happen to encounter a block pattern which is not on the image then your combo is off.
There are total of 29 cases of which you'll encounter. Goodluck!
