Reach Level 10: Upgrade the bottom three 2x, then alternate upgrading top three - bottom three each level. Move up diagonally to one, then again, then fill across right. Constantly move your forces to the boxes bordering the red, from your boxes on the back lines, and take over the close red boxes whenever you outnumber them by enough. But don't attack if you won't win. If they advance near you in the beginning, take them out. Click like hell boys!
