Yes.  On the surface, it's very simple, almost like a 1v1 card game.  Stacking units of the same type and color charges them for attack, so you have to move them around and line them up.  On the other hand, line them up horizonally and they turn into a defensive wall, so you have choices to make.  Powerful units take several turns to charge, less powerful units take less time, so there is strategy involved.  The goal is to break though and hit the 'general', which is simply represented by the rear wall.  Often, though, you'll be attacking strong enemy units to destroy them before they finish charging.  The big guys in the picture below can do serious damage.

Sounds fun! Will definitely download and play. Overall, however, Games With Gold has been a little disappointing so far, especially compared to PS+. I know these games are free to keep forever, which is obviously better than Plus, but the line-up is definitely inferior.

Nice! I have to say, this game does sound very fun. Thanks for letting me know what type of game it is

Thanks. I look forward to another free game.

I heard Sony apologists say Sony makes money by selling expensive propriety memory cards.

Looking forward to trying it out.
