Even turning the sound off in the settings it still plays. I’m usually listening to music so don’t want to just turn my sound off. It’s a conundrum. Otherwise it’s fun ### 4/5 — Cult Bug *2023-06-01, version 1.3* When I press the “Yes” button to reset with the cult, it hangs on the image of the cult symbol and the music gets quieter. It won’t let me reset. What it will do is let me go back as if I never pressed the yes button. This is on an iPhone 12 Pro with the latest IOS software, will edit this part with actual version number. I like the game and will give it 5 stars when the cult bug is fixed. I really do love the game. I like that it’s a black background, easy on the eyes, I like that there’s a circle graph that tells whether I can buy a thing even when the text is small, Depending on implementation details, maybe Voiceover might work wor this game. What I’m saying is, I will give 5 stars when the Cult bug is fixed and I’ll actually be able to apply the cult members I’ve accumulated. I’ve been learning about coding vis YouTube videos, please reply with an email I can use to get ahold of you, I would love to discuss game development with you, it would be a wonderous learning opportunity! ### 4/5 — Cult still broke *2023-05-03, version 1.3* Fun game but when I press the cult buttion the game j ### 4/5 — Sacrifice is bad *2023-02-01* Their is a few days of fun before you hit a roadblock/error in the game where it becomes extremely hard to move forward ### 2/5 — Cult problem *2022-10-05* The games freezes when trying to form the cult. I don’t understand what is happening here but it transitions to just the star formation on the screen and stays that way indefinitely or until the game is forcibly closed. ### 3/5 — Can’t sacrifice *2022-09-17* The game is good and aesthetically pleasing, of course, but please, fix that big that won’t let you sacrifice! The star on the sacrifice screen just stays on and you can’t progress. ### 4/5 — Игра виснет *2022-06-17* Когда делаешь жертву ### 2/5 — Cult *2022-05-04, version 1.3* Ever time I try to use the cult system the game just pauses on the crystal screen ### 4/5 — Needs updating *2022-02-22* A game that I’ve been playing for a long time now but now it feels like a legacy game that needs a new update, there is one part that used to work but now entirely doesn’t and the devs have ignored this fact because it’s old but still that shouldn’t mean it should be forgotten, because some people still play it and want to see it in a new fashion way ### 4/5 — Отличная игра *2021-09-27* Игра супер. Исполнена в моем любимом минималистичном стиле. Но, по достижинию sacrifice почему-то ничего не происходит( ### 4/5 — Sacrifice Issues *2021-06-26, version 1.3* So far, been a very nice simple incremental game. But, having reached the “Sacrifice” section of the game, actually attempting to Sacrifice just begins an infinite looping animation. Reopening the game just results in it acting like I never sacrificed. ### 2/5 — Please! Update! *2021-06-14* I have come to find that the game is kind of broken, after some years passing, because with the screen-reader, and voice-over, I cannot access the video when sacrificing to the cult. Would you please fix this? I feel like there's so much I'm missing, but having it locked behind something I can't do is just... ruining the fun of the game. ### 2/5 — Freezes on cult *2021-04-04* Freezes on cult iPhone 12 ### 3/5 — I can no longer sacrifice my Dragons *2020-12-13* I really enjoyed this game, but I am unable to sacrifice the dragons to gain new bonuses. Initially, I thought this was a problem with Voiceover, because I use that screen reader. But I had a sighted person look at the game, and he told me that whenever he tried to sacrifice the dragons, nothing happened either. I really hope this will be fixed soon, because I would love to give this game five stars. ### 2/5 — Не работает *2020-11-19* Обновите приложение ### 3/5 — Can’t sacrifice all dragons now! *2020-10-15* Kvetha frikai, I have been playing this game for a while now, but I can no longer sacrifice all my dragons. When I could before, a video player option showed, but VoiceOver didn’t work with it well. I had to act as though I was closing the app and open it again to initiate te sacrifice. I try that now, and nothing happens. What to try next? I’m sure I have enough mana to do this but can’t. ### 4/5 — Game freeze when I Cult *2020-09-30* On iPhone XS plus when I do a cult. Game freeze ### 2/5 — Really fun incremental game but... *2020-07-10, version 1.3* I am running into a problem where the sacrifice does nothing and just goes on a continuous animation loop. When I restart the game it just starts as normal as I didn’t sacrifice. ### 3/5 — I want to love this great game. *2020-05-09, version 1.3* This game perplexes me on so many fronts. It’s basic premise and structure is good, very good in fact. But the lack of information and the constant wondering “was that supposed to happen or was that a bug?”. Just now as I loaded up the game to check in on the progress made since last night and to spend the accumulated mana, it happened again. I upgraded my egg production to 1.5M per second. Then I go into the cult section and notice that there is a new upgrade option(I had just done my first cult reset last night) and I see that I have 150k cult points to spend on the upgrade. So I upgrade it up till I can’t any longer. It’s a fire production multiplier. Good right? So I exit the cult screen and something seems off. I go to my dragons and try to produce some but cannot achieve the numbers I was getting only moments before. So I decide to check my egg production and to my surprise my egg production is down to 134k a second. Quite the drop from 1.5M. And again I’m left wondering, was that supposed to happen? I only upgraded the cult upgrade 3 maybe 4 times. And it was supposed to upgrade my fire production, having nothing to do with egg production. It makes no sense. Often in this game you feel like the “math” and “calculations” being done by the app are just made up as it goes along. Once I had the right amount of fire but it wouldn’t allow me to upgrade my eggs. Then I spend a huge chunk of fire on something else and boom it lets me upgrade the eggs and says I have enough fire. It feels like a game with my 6yo daughter where she’s making it all up as she goes along. Often you buy a small amount of dragons and it has a huge benefit on production of the next lowest dragon, yet you purchase a huge amount of that same dragon and production of the next lowest dragon barely goes up. And you can literally test it, you can keep hitting the buy button repeatedly for 30 seconds and watch the production of the next lowest dragon climb rapidly. Then you can immediately do the opposite and allow eggs and fire to build up for 30 seconds and purchase all of the dragons at once, and when you do the production of lower dragons will not jump anywhere near as much as it did when you were buying the dragons repeatedly for 30 seconds. You would think, what does it matter if I buy 1000 dragons at a time, every second for 30 seconds, or if I wait the 30 seconds and buy them all at once, still 30k dragons I’ve bought right? Nope not here, your production of the next dragon will be different in both situations. See dragon A produces dragon B, the more of A and the more of B gets produced. So 30k of dragon A should produce the same amount of dragon B regardless right? Nope, you get a better benefit by buying 1000 a second then you do from waiting. Which makes absolutely no sense, but again you wonder is this some sort of game feature or a bug? There is very little instruction. Absolutely no documentation to explain what each thing means, like the cult stuff. Nothing nada. When you click on settings and then click to visit the company’s website you are redirected to a spam webpage every time. This game could be brilliant. Make it free, add some in app purchases for upgraded production and fix the algorithm. It’s addicting, very addicting and fun when it works. But that doesn’t happen often. It seems as tho the developer has abandoned this app. That’s a shame, because it is in depth, brilliant and fun. Just needs the bugs squished. ### 2/5 — Sacrifice doesn’t work *2020-02-01, version 1.3* Sacrifice doesn’t work, the gem shifts up and then just sits there ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken :( *2026-03-19, version 1.3* I love this game, but the cult/sacrifice mechanic seems to be broken. The game just freezes when you try to use it. When I look this up online I see this has been an issue for years, so it doesn’t look like the dev is going to fix it :( ### 1/5 — Sacrifice broken *2023-09-30* They built a fancy visual effect when you sacrifice. That crashes the app and it never comes back. This used to be a fun game. My guess is if they pulled out the effect things would work again but the game is abandoned ### 1/5 — Deal game *2023-01-24* Freeze when you do the re-incarnation mechanique ### 1/5 — Hit a wall early on. *2022-05-15* I hit the wall very early on this game. Only a day in and I’m looking at probably a week to get to my first cultist. What’s the point of making it so slow? Not worth your time. ### 1/5 — Broken *2021-11-25* This used to be a pretty fun game, if buggy. Now the cult is broken, so you can't sacrifice your dragons for bonuses. Also, the domain for the game has expired, and been bought by someone who is using it for scams and/or malvertising. I opened it from the about page three times, and got a different site every time. One of them was a VPN scam. ### 1/5 — Cult Sacrifice Broken *2021-08-22, version 1.3* Good game until you can’t advance because sacrifice doesn’t work. No updates at all, the game is dead. ### 1/5 — Unfinished and abandoned *2021-02-21, version 1.3* This is an idle game that had potential, but it is unfinished and breaks after E-308 as the developers did not use a math library supporting huge numbers. That represents only a few days of playing. Your actions also don’t have much influence over the prestige mechanic after the first hour or so. It really feels rushed and incomplete, with no satisfaction after the initial discovery. ### 1/5 — From 5 to 1 Stars *2019-11-06* I originally had this as a 5 star review.. but then I got as far as the devs had finished. The game is simply incomplete. The later cult ritual cards you unlock are broken and haven’t been fixed in the 3+ years since the game launched. The devs stopped updating and the game is broken in the endgame. Not worth the time or money ### 1/5 — Boring *2019-02-21, version 1.3* Boring text based game with no real action. I got it for free and was disappointed, don’t waste your money, at least other text based games have some graphics, while this game has nothing but text. Invisible dragons was a good name though because there are zero dragons seen during gameplay. ### 1/5 — Gets boring real fast *2019-02-21, version 1.3* Don’t get me wrong the game is fun, for a few minutes, then there is nothing but the same thing over and over for hours. It’s just a tycoon game with no graphics, no quirky fun animations and sounds, nothing. After a few hours of play it’s kind of like using a basic calculator as a game machine. ## Most praised reviews (10 highest-rated) ### 5/5 — Amazing game *2022-10-14* when you sacrifice, it takes a long while for it to load, pls fix ### 5/5 — Update Please *2019-11-22* I just found this app not too long ago while scrolling the AppleVis game directory. It’s a fun game. But, it needs to be updated. ### 5/5 — Surprisingly Entertaining *2016-12-09* Quite addicting. ### 5/5 — Awesome game (but small annoying bug) *2016-12-03* Hi! Thank you for a game. I am playing to it last month and can't stop. So, I made about 6 sacrifes, received ultimate boost. I see the Skelatal Dragon and Huge Skeletan Wyrm, and can't wait for next dragons. One bug is annoying me. Nitifications about mana upgrades (tower, mana speed, mana capacity, spell power) works incorrectly :( Chaning the sliders "notify" in mana section do nothing, and I always see some notifications buble. ### 5/5 — Happy *2016-10-12, version 1.3* I have play a similar game on the web. I really love it, but i am so happy to find similar game on phone. More easy to play. Really love it and the story too :) Just keep the great work ### 5/5 — Hours of fun! *2016-09-30* I loved the game! Finally got to the end today. However, there's a couple bugs that significantly interfered with gameplay: -Numbers larger than 1x2^1000 overflow to 0.0 (which almost causes a kind of virus that spreads to all other numbers in the game). -There's some weird scrolling effects on the Fire screen. When I scroll quickly late game, I'll see numbers change when they first appear in the screen and false notification dots will appear. ### 5/5 — great *2016-09-10, version 1.3* fun ### 5/5 — Confusing at first, but crazy fun *2016-06-24, version 1.2* This app has gotten me totally addicted, and I have never been this addicted to an app before. If an app has in app purchases, it immediately makes me less likely to enjoy it, so the lack of in app purchases in this is great. The only problem I had is that I don’t think that the tutorial explains enough. There are some circles filling up, some already filled, same colored and some greyed out, some dragons were automatically being created and some weren’t, it was all so confusing. I was going to uninstall initially after being overwhelmed by so much confusion as to what was happening, but I am so glad I didn’t. I did eventually learn the mechanics and it is now one of my favorite apps I’ve ever played. I could definitely see other people uninstalling after not knowing what to do, so I think the tutorial should be updated to include those things. Also maybe break the tutorial up a little more, instead of being all at once, so I can understand each mechanic on my own, before being immediately shown a new one. Also, I feel like the app icon should not just be plain purple, as it doesn’t really reflect the app itself very well. I think a better option would be the rotating object in the cult tab. In the end, everything worked out for me though, and I am having an amazing time with this incredibly addicting app! ### 5/5 — Awesome *2016-04-09, version 1.2* My mana section disappeared in the new update. And on the apple watch there is a typo in the glances, rather than saying invisible dragons it says ivisible dragons but the game is really good, not like one I have seen before. ### 5/5 — Amazing game for those that like a game to keep your mind busy *2016-04-08, version 1.2* Edit in regards to the top post. I hit the same issue, but it just keeps you at max fire as far as I can tell. As to a fix, honestly at this point I don't care if the game just broke nE^x where n and x a separate numbers. There would be rounding but accuracy in these numbers wouldn't really effect the game. >.<. I have been playing intensely for to weeks, yet this game dose not require a the micro management that I like. It is a great game for someone that likes to engage your mind deeply or just have something light while you are waiting on someone. There was a review that talked about a cult bug that broke his/her game. I have used cult 3 times and so far haven't found the issue they are talking about. This is honestly the best money I have ever spent on a game. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
