I am getting tired of never being able to complete challenges because of too many "blanks". Looking for other games to play. SORRY CAN'T FIND A CONTACT US BUTTON. Agree with other reviews that you lose all your "coins" chasing spins, dice, darts etc to finish challenges, and also the cards - you get too many useless repeats and battle to finish albums. I had over 30 trillion credits and 2 days later nothing and challenge not finished. The losses are too many and the wins too few.
