Both Supercell games are synchronous but stuff like editing village and saving it for later, fast train barrack troops, chat, attack and defense logs, card data used against players, trophies, single player campaign are all semi-synchronous as those data are stored in the device. If you lose your connection during a PvP battle, you lose the deal but during those other things, they are restored.

Semi-synchronous is a good thing, in fact better that both sync and async combined. Don't let the name make you think that it's bad or not as good as the other two. That's why this mode is the hardest to produce because of how much resource is needed to run such a complicated process. Google's own GCS/2.0 is the newest example of such a semi-sync server which is what we use to browse the web since 2014.
