## Slime Castle Reviews in United States

### ***** "Awesome app"
Easy to operate
-- Shermhan, 2025-03-09

### ***-- "Addictive"
I love strategy games,  Amstel defense games I seem to get addicted to. 
Since the last update I can’t collect my idle or my quest rewards, it says “unauthorized user prohibited”.  How do I fix this or can you please fix this
-- fhgubty, 2025-03-07

### *---- "Don’t buy anything!"
I downloaded this game and enjoyed it enough to purchase the “remove adds” bundle, after logging off and returning later, my progress and purchase was deleted and it showed no evidence of a saved game, do not support these scammers.
-- Charlie5144, 2025-03-06

### ***-- "Pretty fun game, but has gaps"
This is a good take on castle defense with a different twist. The major problem is that large portions are pay to win. For instance, to get any (except one) slime that is SS rated costs money. There is no other way to get these slimes except to pay which is bogus.

Also you better be prepared to watch a LOT of ads for additional benefits. While you can eventually watch enough ads to purchase some upgrades you will still be watching a lot of ads to try and advance only to find that you are pretty much stuck for weeks on end to level up your slime (unless you pay for the better slimes) to beat levels.

The game company seems a bit too greedy on getting people to pay. They would do better by awarding people more that will grind and watch ads, but having a pay only tier for some slimes at $32 is crazy.
-- Split3, 2025-03-02

### ***** "Great game"
It’s a great game I love everything about it
-- Fuzumaki, 2025-02-26

### ***** "Fun"
Excremly fun and relaxing
-- jimomobobers, 2025-02-26

### **--- "Its ok"
The game is fun but is easily one of the most grindy td games Ive ever come across. The two biggest issues I have are the endless P2W factors and the lack of an endless mode to grind resources. Over all its okay, but in an already overinflated market, there are better options.
-- PolarStar2218, 2025-02-24

### ***-- "Nothing to do at the end"
Balance your premium offers, I just spent over a hundred dollars in the game and I feel like my return for it was abysmal, I understand you aren’t trying to make it a pay to win system but the fact that your rng system almost always hit 50 for an s item and there is nothing for me to use my gold for is making end game stale
-- Help you sve time, 2025-02-18

### ***** "Fun game, but a couple flaws"
I got this game a couple months ago, and I’ve been enjoying it ever since. I am currently on chapter 6 wave 29. I see what people say about the paywall, but this game is worth the time to get over it. Some of the rebalancing changes in the new update made the game much better. However, it has one issue: Ads. While it doesn’t force ads on you(thank god), they have broken their way into almost every aspect of the game. want X2 mining speed? Ad. Want to open the artifact chest? Ad. The slime shop partially counterbalances this issue, making the game more fun. Because of this, I feel the slime shop(currently lvl 2) should be available in tower of the wise lvl 1, and tower of elements(currently lvl 1) should be moved to tower of the wise lvl 2.
-- Silvernight5768, 2025-02-17

### ***** "Amazing game"
Smile castle is a fun game to play on your free time. The game constantly upgrades and bringing new stuff to game play.
-- Turtleturtlet, 2025-02-15
