Dragon Orb hoard glitching

I can’t find anywhere to report issues but the stupid orb drop will seize up with a connection symbol every other drop and will cause the ball to drop too late.

It’s alright as a passive time passer.

I like playing after work to pass the time but it’s pretty pay to win based.

Nice game

Very fun and challenging

Без надежды на сохранения и поддержку

Всё бы ничего, игра хоть и заточена на донат и на просмотры рекламы, но играбельна.
Однако, при разборе ситуации сброса прогресса учетной записи с поддержкой оказалось, что в игре не работают сохранения, а поддержка, даже при предоставлении всей доступной информации об инциденте, или не в состоянии разобраться в своей же игре, или не имеет на это желания, постоянно ссылаясь на какой-то второй аккаунт, который им нужно предоставить, чтобы они что-то смогли сделать.
А по факту, после сохранения и переустановки приложения, произошел сброс прогресса. Причем в гильдии остался этот же персонаж с тем же ником, что был до утери прогресса. У сброшенной учетки сохранились данные о полученных наградах, например в шахте. При вступлении в гильдию новым аккаунтом оказалось, что сброшенная учетка отображается как старая у учетка, у которой видна и сила и шмот до сброса. И онлайн накладывался учетки после сброса и у сетки до сброса.
В общем, крайне не советую надеяться на то, что в случае инцидента с прогрессом, разработчик игры признает критический баг и как-то посодействует в восстановлении прогресса. Донатить, по этой же причине, тоже сомнительная затея, с учетом того, что в любой момент может оказаться, что всё нажитое погибло.

Not a player friendly game

If you expect to get anywhere and have fun you will pay money and lots of it.. the devs don’t care about the players as recently shown with the 2nd annual celebration. What they did was add more opportunities to buy more of their nonsense. Mind you, when you buy, you’ll need to keep buying. You will get No where quickly. I’ve stuck this stupid game out for over a year just to see me wait 24 hours to do anything exponential for my account and even longer to do anything worth while for my account…. Meaning.. I’d you plan to stick with this game and spend thousands of dollars, you will see some growth quickly… if you play this game because you think it might be fun for free with free ads, you are sorely mistaken…. Expect to start doing the same stupid nonsense for years with little reward to see little growth… take it for what I say but I’ve been doing the grind and I’ve keep getting shown that all the devs care about is tricking you into buying more… eventually this game will burn out.. I personally have seen hundreds leave to what I’m explaining now… good luck, enjoy your few months, don’t buy anything and see how quickly you decide NO. But stuff and see how quickly you decide never again… only time will tell.. good luck
