Zut Games' Pushcat seems accurately described as Boulder Dash meets Bejewelled or Columns with a purple cat doing all the grunt work. The man-cat has a lust for silver and must push and dig until he lines up at least three like-colored gems to make the silver appear. Unfortunately, exploding Aztec skulls, ghosts, and more create challenging push-puzzles for the flesh-striped feline.

Some puzzles require one not to waste any gems, which can fall into pits or unreachable/push-able areas. Pushcat is no cheap arcade thrill; this one requires a bit of brain power!

Pushcat has a free demo on Windows and Mac, and the full version is £5, €6 or $8.
