Calling this game free to play is like calling arusted out old clunker with a fuel line leak free to drive. It's pay to "win" & still lose w/obvious game manipulation to entice purchases, such as very consistent "bad luck" draws during closely matched PVP, immediately followed up by offer of extra attempts to purchase with game currency that can in turn be bought via google play. Also players with a different app version can attack you and you can't retaliate because your version is different.
