Idle Slayer
Idle Slayer is generally praised as an addictive and fun idle game with good progression and no forced ads, but recent updates and late-game mechanics have introduced significant issues like slow progression, intrusive mini-games, and ad-related bugs, leading to a decline in user satisfaction.
Idle Slayer is a free-to-download idle game that has maintained a high lifetime rating, with many users enjoying its addictive gameplay, deep progression, and lack of forced ads. However, recent reviews indicate a trajectory towards frustration due to extremely slow late-game progression, poorly implemented mini-games, and various bugs, including issues with ad rewards and game crashes.

Latest update · v7.0.5

Improvements • Added Slayers Machine new animations. • You can now hold one button to use [Aerial Barrage] and while holding, jump with another button and [Aerial Barrage] will still be active. • Bug fixes. • Quick Tool Belt now grows from left to right, not from right to left. • Souls/Coins yield in the portal selection interface now has 5 stars maximum instead of 3 for better accuracy. • Improved performance when breaking Armory items. • Balance changes.

Who it's for
Idle Slayer is for players who enjoy long-term incremental idle games with deep upgrade systems and a sense of continuous progression R3R14. It's suitable for those who appreciate optional ads for boosts rather than forced interruptions R5R12. It is not for players who dislike grindy progression walls, poorly implemented mini-games, or who expect a purely hands-off idle experience R67R147. Players sensitive to gambling mechanics or recent increases in ad intrusiveness should also skip it R9R98R246.
Evidence note: The recent reviews skew more negative than the lifetime rating, suggesting a decline in satisfaction. While many positive reviews praise the core idle mechanics and lack of forced ads, an increasing number of negative reviews highlight issues with late-game progression, mini-games, and ad-related bugs, which were not as prominent in older reviews. The developer notes for the latest update are minor and do not address the major pain points raised by recent reviews, particularly the ad issues and game-breaking bugs.

- [R1] First Review: I’ve never reviewed an app before, but this one is fantastic.
- [R2] Such a good game: Love it so much thanks
- [R3] Fun game!: I've recently come back to this game after not playing it for an extended period of time, and still love it! My account is 5.5 years old (2027 days), which was nice to come back to and keep playing. The development with the story and overall gameplay is good. The balance between online and offline play is also done well.
- [R10] Five stars: Its really fun
- [R5] Great idle game: Music is S tier and not one as has been forced upon me. Very grateful for that.
- [R12] It's crazy to me...: ...how fun this game is without shoving microtransctions or ads in your face. Both are there as options to give you an extra boost but are not forced in any way. And the gameplay is really fun and in depth for an idle mobile game.
- [R14] Addicting game: I’ve been playing for almost two years now and this game is honestly pretty good. Unlike most other idle games, idle slayer has no forced ads, has ton of scalability especially with the ascension upgrades, and honestly for an idle game, it isn’t really that repetitive. If you’re looking for a game that’s addicting with no ads, I recommend this game for you
- [R25] If the devs see this then please thank interndotgif: This game kept me going when pets died and I wanted to kill myself. It’s well developed and doesn’t give you ads every 20 seconds it also is just a really fun game that is worth the time it takes to get high level. I thank the devs for this game.
- [R19] Great game in my opinion: Honestly such a time killer I feel like this game is good to drop off and come back too cause when you come back you've made so much progress such a good game the discord server has such a good community
- [R42] addictive game: the fact you can double your rewards with ads is overpowered, I decided to like.. wait for 1-4 months and I got double of it, sure, sometimes it’s just a waiting game but the rewards are very worth in it, the aspects and art changed a lot as I played over the 1-2 years
- [R45] Review: Decently fun, Idle rewards are good
- [R51] Great game! (Found an addiction): This game has SO many cool features that I always look forward to seeing! I love the story and it’s always so cool to find what the next update brings! 10 out of 10 would play, it is great for a car ride and fun when you you have time to play! Also I LOVE that this game never lags on me anytime and anywhere!
- [R8] Has gone downhill: I have been playing this game for well over a year now and have enjoyed it thoroughly, however the grifting and intentional manipulation of RNG has gotten to the point of ludicrousness. Betting at the slayers lounge? You will roll 10 black tiles in a row on roulette getting your chips. Ask me how I know. Trying to get that excellent armor to progress in the village? Open THIRTY
- [R11] Leeennto: Todo iba bien hasta que se notó que no me dejaba avanzar más upgradeaba el equipo y de inmediato subían mucho el precio siempre limitaban la subida y los anuncios estaban bien pero metieron uno de football que duró más de 3 minutos y no lo podía sacar
- [R39] Brutally slow progress: Yes, even for an idle game.
- [R43] Great fun and way to pass time, but I’ve hit a road block: The game is great! I’ve started a couple days ago and get pretty far along when I ascend and do it over again with better stuff. My biggest road block is when I hit the Sx tier of money. It just goes by so slow. There are no more gear to buy to increase the cps by a substantial amount, and the upgrades that cost a fortune don’t help either
- [R15] Remove grappling: The design is objectively poor quality with mobile controls. Character upgrades are locked behind it.
- [R17] Soul grapple test course makes me sad: If the soul grapple is gonna work this poorly on mobile you could at least make the time more lenient. The camera is far too zoomed in for the level design, and the controls desperately either need multi touch support or better multitouch support because they barely function
- [R31] delete the soul grapple chambers: they are sooooo unfun, it sours the whole game. terrible controls, awful level design, no fun to be had there.
- [R52] Decent, look at steam reviews: Steam review spread more accurate than the 4.8 it has on ios store. Not really idle at all, the grapple and doodle jump knock off minigames are really lame on mobile. Heavy on the micro transactions, its just a few things at first but the farther you get into the game more things get added to the soul gem store. Yes you can get free soul gems but theyre few and far b
- [R7] Fun, possible bug?: I like the game a lot, and I genuinely have no complaints except for sometimes it seems like despite having a stable internet connection, the options to watch ads either don’t show up, or just don’t work. I like to watch the ad to find the saver in the chest hunt, but the option to watch the ad just isn’t showing up anymore.
- [R54] Pretty good game BUT: Game is fun to play, but when you watch their “ads” to get a CPS bonus or to speed up the time for your minions, there is no “X” to close out of the app after watching it for 30 seconds or more, forcing you to force quit the game, log back in, to then realize that you did not get the reward. I’d rate this 5 stars, but keeping it at 1 until that’s fixed.
- [R93] Unable to get AD rewards: Every time I try to watch ads for the rewards the 2nd ad 2 of 2 closes and I get nothing. I have wasted so much time trying to reload or redownload the game. Losing progress sucks and watching 1 video and getting nothing because the second video will not load is awful.
- [R151] Can’t get rewards because ad won’t go away: It’s annoying to watch an ad just to get the reward just for that ad to stay there and not go away. I have to shut down the game to remove the ad and lose my reward. Not work watching ads if I don’t get anything from it.
- [R80] Was really good: The game was fun and my go to game for free time at work. After the most recent update my game is now filled with ads. The two options at the top of the screen when you load the game didn’t play an ad before but now do.
- [R83] Developer got greedy: If you like watching ads, this is the game for you.
- [R98] It was fun at first: For the first week or so the game was good. It was fairly engaging and didn’t force ads on me but all of a sudden starting today, just to receive your offline gains you have to watch an ad. That’s unacceptable. I understand you have to implement ads but why are you forcing them… that’s how you lose audience. That’s how you lost me. As soon as i was forced to watch 2 ads back t
- [R102] Egregious advertising: This game was cool till I had to start watching ads to collect my AFK coins. What were you thinking? Uninstalled
- [R18] No Apple account option for non android users: I’m not going to even finish the tutorial because there’s no option to sign in with an apple account for non android users.
- [R95] Not working…: I recently redownloaded this game and when I go to play it it goes to the “wake up slayer” dialogue with the purple soul blinking. But after the dialogue it just goes back to the “press start” screen and replays the dialogue again. Please fix! Thanks.
- [R97] Can’t even play: I can’t even get into the game, I logged into a super old account and now all I get is trophy’s and than before the game can start I get sent back to the main screen . Unplayable
- [R140] Can’t play: No matter what I do, click through the dialogue as fast as possible or don’t click at all. Within about 15 seconds of “pressing start” the game resets back to the press start screen. Whether I don’t click anything after the first time or try to speed through the dialogue. If I don’t press on the press start screen then nothing happens at all
- [R182] Annoying: If you get an souls boost from a box the game will not allow any more than 2 creatures to spawn in the next 20 seconds. I’ve been playing for over a week now and all of my tests have given the same results. What a scam.
- [R246] Has gambling mechanic: This game would be a decent time waster except for the chest hunt mini “game”. It’s just a gambling mechanic that doesn’t add anything good to the game. Would not recommend this game simply because of that. Edit: there’s a slot machine and roulette that hold more necessary upgrades. Any bonuses are lost upon closing the game which is about as dumb as it sounds for an idle ga
- [R9] Bait and switch on ad free purchase: There’s an option to get more resources by watching an ad. I did that a few times, then bought ad free for 10 bucks so I could get the bonus without watching - and now the ad tier costs 10 gems instead. Sucks because I was enjoying the game.
- [R23] Disappearing bonuses: Getting my game interrupted by a phone call that took less than a minute to resolve, took away both my x9 multiplier and my Daily x9 multiplier
- [R38] Bad: I started playing and then I fell asleep and I was still at zero coins and I didn’t get any money. This game sucks.
- [R192] Fun for a bit: Fun for a couple hours, then gets too grindy. Offline progress doesn’t work.
- [R22] Chest Hunt not working properly: I love this game dearly and I play it frequently, however recently I’ve gotten a bug that causes chest hunt keys not to appear after unlocking the upgrade. And knowing these are a major part of the game, this bug is beginning to ruin the experience. Please fix soon.
- [R20] Gets boring after awhile: It fun for a little bit but after a month or so it gets repetitive
- [R32] I like game, but it gets boring: After a while of playing this game, I have a come to clue that this game is a little boring. It barely gives you ads, but all you do is just sit there while the money grows. I wish they had a mini game that you can play and when you play the game, there’s a chance that you could probably get a boost for your money just like a random boost
- [R56] Meh: It was an interesting experience. Very…minimalist. Variety was few and far between and the variety that was there did not distract from the numbing loop of making coins and spending it to make more. The powerups in shop were like 3% increase and the increase in prices did not scale with the amount they generated
- [R107] It got boring😭: There was nothing to do on it. I always have to wait every weekend to get the souls. And it did barely nothing.😭😭
- [R147] Decent Idle game: The game is decent. Skill tree is very expansive allowing you to get stronger through different ways. Biggest problem for me was how SLOW the progression is. Yes it’s an idle game but i would literally idle for a week and spend hours in game because I’m stuck at one ascension. Also the non idle aspect of the game is quite boring and repetitive. Think of endless Dino jump game. 99
- [R67] Not actually an idle game: As soon as you get any real progress into the game it gives you stupid little mini games like the incredibly poorly coded grapple mini game or the platform hopping/wall running mini game for some reason? Like honestly just put the fries in the bag bro you coded an idle game not super Mario
