Guys it seems Arkadium has updated a new point system. The challenges have been categorised as 'easy, medium or hard'. They have put stars at the top - one * for easy, ** for medium and *** for the hard challenge. Easy gets 100 coins, medium 150 coins and hard is rewarded with 200 coins.
1st April had 3 easy ones and 1 each was medium & hard.On solving all 5 challenges you therefore earn 900 coins as against 750 earlier. That I think is cool. Apparently the Arkadium guys are AWAKE and 'improving'.
I have just finished the Daily 5 challenges for 1st April and happy to earn 900 coins.
