“You can use portal, only thing is you must be connected to facebook.”
Actually that’s not exactly true. I don’t have FB but I use the Portal. However, you can only gift to that NPC “Mr (somename I can’t remember)”. But you can get a tiny energy bump from his Godchildren too. You can also buy decorations therefore, Pillars! Very handy compared to mobile version as no gems needed. So to fully utilise the gifting you do need FB connected, but at least you can get some extra achievements even if you play on your own.
