Rewards for playing clash!!!
A player who plays more that 30 min a day for a week on clash of clans should get a 200 gem reward JUST FOR PLAYING EVERY DAY FOR A WEEK, and look forward to playing the game next week for another 200 gems and so on! THIS WILL keep people active on the game and will allow players to upgrade or boost more frequently, thus players playing the game more often. Also, this will promote buying gems, as some player may see that gems give them an advantage to those who only only take the 200 gem reward. Yes I know players may try to save the gems for variouse upgrades but it would take a whole month of playing to almost reach 1000 gems. This would benefit mainly the lower town halls and would also benefit farmers who boost barrackes to raid more frequently. Over all this will attract new players AND keep old ones on every day!
