>How do I summon Sylvester Kacheek
Sylvester Kacheek can be summoned by pressing the letter “K” on your keyboard at any time but only after you have completed a set of 4 lines.
I press “K” but nothing happens
This is because you have not yet completed a set of 4 lines. To do this, line up your blocks until all you need is a straight 4 line block to slot in.
