This WAS a fun game, until it was changed.
It’s entertaining and makes you develop strategy. I was playing it most everyday. BUT THEN THE GAMEPLAY WAS ALTERED WITH AN UPDATE, which IMHO has spoiled it. OLD STYLE: if you couldn’t combine two number tiles, then the numbered-tile columns would slide up only one space at a time. NEW STYLE: now, the numbered-tile columns slide up two spaces at a time, which means that you quickly run out of vertical space. I wish that game developers wouldn’t always feel the need to change a good thing. I’m taking this app off all my devices.
