Unlike many match-three style puzzlers, Columns differentiates itself by staying true to its name: colored gem types rotate vertically, allowing only for top to bottom, horizontal and diagonal combos of three or more. As if that (and the big, chunky pieces that fill up the screen quickly) isn’t enough enough trouble, the difficulty on this one is for serious players—medium is as fast as many match-threes advanced levels, while hard can leave your screen a crowded mess of mismatched gems in a matter of seconds.
