I tried redownloading the game cuz i missed it, and i cant even get pass 40% on the loading screen whenever i boot up the game ### 3/5 — Сохранение не работает! *2026-06-05* Добрый день! Игра хорошая , интересная, затягивает хоть и мало разнообразий. Самое главное не рассчитываете на сохранение игры, после удаления и вновь скачивания игры, сохраненный контент может не загрузиться и все можно потерять ранее пройденные миссии. ### 3/5 — Игра красочная и интересная, но есть еще что надо доработать *2026-05-29* Играю в эту игру небольшое количество времени. Красивые локации и слаймы, много заданий и наград. Однако, есть моменты, которые можно улучшить: - Часть содержимого на экранах (например, логово дракона) перекрывает динамический остров - Если начал случайно проходить бой не в той локации, то нет возможности завершить бой досрочно (так и не удалось найти кнопку «Уйти») - В какой-то момент на кнопке объединения экипировки всегда начал отображаться восклицательный знак, который не убрать. Постоянно вводит в заблуждение, так как непонятно действительно ли есть вещи для объединения. - Так и не удалось нигде найти кнопку техподдержки, чтобы оставить информацию о проблеме. Пришлось писать здесь. ### 3/5 — Needs little more work *2026-05-15, version 2.10.4* You need a little more work fatty As mommy Reese’s pieces your mommy Jesus ### 1/5 — Don’t buy ad skip *2026-04-18, version 2.9.9* I paid for the unlimited ad skip and found out it was only for 30 days and a friend just told me is is permanent for him. And through research learned that the permanent pass is server based. ### 4/5 — Cloud Speicher *2026-04-03* Wie kann ich denn meinen Speicher vom iPad im iPhone laden? Wenn ich am iPhone das Spiel öffne fange ich bei 0 an… Ansonsten mag ich das Spiel sehr :) ### 1/5 — Cash grab, Not worth the time or money *2026-03-31, version 2.9.7* Don’t waste your time or money. .. just being honest. It’s a lame game that has no real feelings of accomplishment unless you spend money. If you spend money expect to spend more than you would ever pay for a real console game. You’d end up spending 100 times the amount you would normally spend on a console game. Once you’ve earned everything there is to earn, you now have nothing to show for it except an account you spent hundreds or thousands of dollars on.. in all honesty the game is boring with VERY slow progress. ### 1/5 — Rebalance = Nerf of paid items *2026-03-31, version 2.9.7* The “rebalance” in the newest update completely destroyed the game, weakening everyone significantly, including enemies, but somehow leaving everyone in a net-worse position, including those that paid for items or slimes. It’s common in games like this to release new content that is suspiciously-hard without some new pack they conveniently launch at the same time, but actively making existing content worse is beyond the pale. I’m done. They’re not getting another dollar from me. ### 1/5 — The new update *2026-03-30, version 2.9.7* It’s not that good anymore we wasted everything we had and everything gone with the new update not playing it anymore ### 1/5 — STOP CHANGING THE LAYOUT *2026-03-30, version 2.9.7* Devs PLEASE STOP CHANGING THE HOME PAGE LAYOUT. Every time it changes important/frequently visited tabs are in a completely different spot for no apparent reason. If these changes made sense from a UX/UI standpoint I would understand, but seriously flip flopping everything around is serving no purpose. Things aren’t easy to find. The grouping of items doesn’t make more intuitive sense. Please just stop. 😩 ### 1/5 — Бесполезное трата времени *2026-03-29* Игра без автосохранение , а ручное сохранение не сохраняет данные , постоянно начинать играть с нуля ## Most critical reviews (10 lowest-rated) ### 1/5 — Dragon Orb hoard glitching *2026-08-22, version 3.3.5* 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. ### 1/5 — Nice game *2026-08-21* Very fun and challenging **Developer response:** Hello! We would like to hear more about this issue and help solve it. Please go to the game Settings and tap a button called Discord. On the game's Discord server, you can submit a bug report. If you decide to go to the game's Discord server, then it would be great if you could submit a detailed feedback. ### 1/5 — Без надежды на сохранения и поддержку *2026-08-16* 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. ### 1/5 — Billchok *2026-07-16* For the past few months, your game has been running really poorly; during every session, it crashes two or three times I've been playing on a fairly recent iPad for three years now and everything was always fine, but not anymore, which is rather sad. ### 1/5 — Remove the adverts that don’t play *2026-07-15, version 3.2.6* ^^^^^^^^^^^^^^^^^^*^^^^ ### 1/5 — Whyyy *2026-06-25* Why can’t I log in? **Developer response:** Hello! We would like to hear more about this issue and help solve it. Please go to the game Settings and tap a button called Discord. On the game's Discord server, you can submit a bug report. If you decide to go to the game's Discord server, then it would be great if you could submit a detailed feedback. ### 1/5 — Вылеты *2026-06-07* После последнего обновления на iPad mini 2019 игра постоянно начала вылетать ### 1/5 — Focus is on nonsense rather than proper enjoyment *2026-06-05* They add more nonsense and make changes so there can charge for more. Not necessary to add more things until the game is in a position to have no more problems or bugs. But no. They just keep focusing on how else they can draw more money from their users. Almost deleted the game Monday. For some reason the game decided not to engage the bingo game that normally starts on Monday at a certain time. I did all of the requirements to get all the hammers just to find out none of them were recognized because the game wasn’t available yet. It’s seems to be problem after problem with no hint of getting better. Except they do keep the money making operations strictly running efficiently. Not sure how much longer I’ll continue to put up with this game. It’s boring, slow, money grab, slow, nonsensical changes, and slow. Wish I could actually do something more than check in once a day just to do simple daily tasks that take as long as it takes for the auto travel takes. Then I don’t pick this game up until the next day at the same time. I wouldn’t spend money on a game that only makes sense to play once in a while. **Developer response:** Hi!

And through research learned that the permanent pass is server based. The game started to purposely funnel new players into a subscription based reward system 100% do not recommend this game as predatory practices ### 1/5 — невозможно играть *2026-04-22* Как восстановить покупки? **Developer response:** Добрый день! Нам жаль, что у вас сложилось такое впечатление об игре. Мы активно работаем над новыми функциями и улучшениями, чтобы играть в Slime Castle стало еще приятнее. Надеемся, вы попробуете дать игре еще один шанс! ## Most praised reviews (10 highest-rated) ### 5/5 — Not a player friendly game *2026-08-10* 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 **Developer response:** Hi! We’re really sorry to hear that your experience hasn’t met your expectations.

And this is coming from me, frontline soldier on the anti-ad war. Every single ad is optional. I’m certain if I wanted to I could just not see ads, but this is the only game I’ve ever tried (and I’ve tried so many lately as I’ve been recovering from surgery so my mobility has been limited the past couple months) where it feels genuinely worth it to click the ad button and then do something else for the next minute while leaving my phone muted and then when I pick it up again I’ve got a nice amount of rewards I can use to upgrade my stats or gear or what have you. The game is fun and it feels like I’m making good progress consistently (we will see how this holds up over an extended period ofc, as I’ve only been playing for a couple days). The idle rewards building up even while playing is ingenious. The different mini game things are cute (I particularly like the gigas battles now that I’ve got some power in my slime). I was surprised by the slime town thingy and it’s piqued my interest enough to try to save materials for it. Unlocking my dragon skill was also a fun surprise. This isn’t one of those gacha games where when you start they give you one of the current “best” characters or whatever to try and make newbies feel like they’re reaching longtime player level, but I think that’s for the best here. I only have two slimes right now and it doesn’t feel like I’m missing out. I don’t feel like I’m underpowered and I’m excited to eventually get more of them. The ONLY thing I would want to add, and this is purely a personal idea, is the ability to have your own sort of “player slime”. Maybe not one that can be used in the battles so it doesn’t overshadow the character slimes, but one that represents you and can be customized with different colors and accessories. That would be really neat but that’s again a personal preference cuz I’m a big fan of customizable characters haha. Genuinely would recommend. I hope the devs are having fun with it. ### 5/5 — Unique Gameplay. *2026-06-30* This game is one of a kind, it offers unique gameplay, has leaderboards, and it doesn’t have forced ads. (though I can’t seem to get some things for the event to unlock an SSS slime) It lets you level up skills and slimes then start the match over being stronger. You can also unlock things in slime village to become stronger. (If you can’t get into the game at some point then try restarting your phone) ### 5/5 — Fun, and enjoyable. *2026-06-05* I have been playing for a little over 6 months, I enjoy everything you can do daily, but my one and only question I don’t like is $40 per new slime hero… Aside from this, I really enjoy the game. :) ### 5/5 — Сказочная легенда *2026-05-22* Игра классная как бы оценка 5 ниже не как замечательная это как в сказке именно в битве которой босс мог истребить драконов истребитель драконов в глубинах леса замок роботы сложности есть просто бесконечно развиваться до максимума но сейчас дошёл до ночного замка волки просто смертоносны если не улучшить то могут разобраться 1 удара снести щит а другие враги опасные как бы сейчас было очень много врагов и ещё духи и увеличивая скорость +5% каждое время но разобрался это сказка интересности есть ### 5/5 — It’s good *2026-05-16, version 2.10.4* I like it ### 5/5 — Grade *2026-03-29, version 2.9.4* I love the game it’s cool but please make the speed go to x4 and the powers charge faster/love:Enmanuel Inoa ### 5/5 — Thank you *2026-02-28* My main thing was free to play mainly because I cannot afford to spend money but this game offered me something other games couldn’t fun and free and no pay walls… the music on the main menu I don’t understand why but it’s giving me sad yet happy nostalgic feeling like I’m remember past times I miss so much in my life as if to remember chapters of my life I only dream of being able to enjoy and live again I know my review may not mean anything to anyone else but as a active guy who’s getting older and seeing how I’m not as active in a sense as I used to be this game the music has some how given me some peace that’s it’s ok that I’m getting older so thank you ### 5/5 — Neat *2026-02-23, version 2.9.2* The game is pretty cool, it has a surprising amount of depth. The only thing I don’t care for is the constant spit sound the slime makes. I wish there was a different sound to make it ### 5/5 — Amazing!!!!!!!!! *2026-02-10, version 2.8.3* No ads, super fun easy to play --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
