I wonder what is SciFI game match. Is it available here? Earlier I thought that SciFi is the same as Quick Arena match. But my opinion seems to be wrong since the achievement "Tactician SciFi" is given when you win the SciFi with 15 of your pieces still on the board, and in Quick Arena (which I never yet played) you have only 10 pieces.
Also I'm interested what are the spotters. They're involved in "Five by five" achievement. Thanks beforehand for any good answers)
