My idea is to have little activities with rewards (or no rewards supercells choice) and a leader board (or no leader board Supercells coice again) that players can between transactions ex: clearing trees, waiting while troops are training, ect.
These games would be like 'defend the wizard tower from an onslaught of troops' or 'fight the evil drak troops with your barbarian king'. These could also be used in tournements for gems and such.
