Gameplay is ok, but to get characters is super annoying. 3stars are easy to get. 4 star rare. 5 star is like negative -1000 chance. Unites is the currency. 135Unites for ($5). 275U for $10. 850U for $30. 1450 for $50. 3100U for $100. To roll for a character it's 300unites. Imagine wasting $15 for the $5 135U + 275U $10. Just for a 3 star character. Or imagine wasting $100 for 10 characters that more likely 3 low star characters. Prices and rates are not fair. Stay away from this game
