Strange game

The game is fun at first, you can advance at a decent pace. After a few weeks, it will become an endless cycle of losing to bots. I can only assume this is an attempt to get you to spend money. I get that apps are designed to make money, but losing free to play gamers, leads to a small base of players. There is no longer a reason for me to watch 40 to 50 ads a day as I still lose 24 out of 25 matches. I’ve spent hours studying strategy for the game and none of it matters.

Problems

It takes so much gold to level up characters that below legendary. Why? They’re horrible compared to legendary. It should be cheap to level up grunt characters essentially. Again, I had big pink dude, Batman, and Princess all level 13. And my team basically lost to a LEVEL 9 electric bird. That makes no sense. I shouldn’t need level 15’s to dominate. 13 is extremely high in level. Fix your game. Have levels mean something like wtf. Give more access to new characters. Yeah let’s make $ by dishing out new characters that you can only buy or buy a battle pass to get that character. Mind you your battle pass fades and you got to keep spending to get the best characters in the game. Make more things affordable and events to get characters more free. I barely write bad reviews or reviews at all, but my experience with this game has shown that these devs care about $ and not the player experience

Ridiculous

If I could I would give zero stars, or indeed minus five. It’s a great game on paper, but I’m at a point where it doesn’t give me golden cards to grow at all unless I pay a lot of money, and the system keeps putting me against players with stronger hero and stronger cards (all of them!) so I inevitably lose all the matches.
Can’t grow, can’t win, all is left I can do is wasting time. What a shameful set up

Remove the bots!!

Just like some of the reviews on here saying that this game is intentionally making you lose, it’s true. This game puts you in a match with bots just so you can't collect your rewards… Which is worse cuz they’re making money off of you playing this stupid trick… do better developer.

Actually good

It’s actually good, fun, and requires skill and has a good glow that builds as the game progresses.
