It’s honestly quite clear that the game just wants you to spend money, either by buying outrageously good players or gems, in challenges, you get chances to retry using 500 gems, but the challenge itself is near impossible, the AI’s team is virtually maxed out, and their attackers can dribble past my defenders with ease, my defenders often don’t even fight for the first ball automatically, which is a severe flaw in the game since you cannot see where the ball goes as it doesn’t show up on the screen until the attacker has it. On the other end, their goalkeeper is often also insanely good, and when it looks like they will concede, the defenders foul you because the goalkeeper will obviously save the free kick or penalty. This was the hardest challenge (Frosty), but it should at least be achievable without paying, and not an extra way to encourage players to spend money. My team rating is 116, and I doubt I will get much further without paying. There are many other ways the game encourages you to pay, such as; shards, where the best players are often completely unaffordable without insane pack luck(which require gems anyway), mystery boxes (basically lucky wheels) where you get one free attempt before having to pay real-life money, and many others.
