Our Expert Score

88/100

As a fan of the anime, I went into SLIME - ISEKAI Memories with high expectations, and it actually exceeded them. Most anime tie-in games are lazy cash grabs, but this is a deep, high-quality RPG. The city-building aspect is surprisingly robust; seeing Tempest grow from a few huts to a sprawling city is incredibly satisfying. The fact that you can walk around your town in 3D and talk to your citizens adds a level of immersion that most mobile RPGs lack.

The combat system uses a 'Soul of Skills' mechanic that makes every turn a puzzle. You have to think several steps ahead to chain the right colors and maximize your damage. The 3D animations for the ultimate skills are stunning—they look like they were ripped straight from the anime. With an original story supervised by the series creator, this isn't just a game for fans; it’s a genuine expansion of the Slime universe. It’s a polished, content-rich experience that sets a high bar for the genre.

Ratings & Reviews

A fantastic game that incorporates the series extremely well
Sat Dec 11 2021 Bush1n

As a big fan of the series I love that you have made a game as fitting as this one that incorporates both the adventure and the town development of Rimuru’s story. I especially loved the fact Great Sage can be interacted with to help you find out what to do next or review things you might have forgotten in the tutorials. The game original story is nicely added in where it does not disturb the canon of the main story and adds interesting new characters and concepts that I thought was fairly fitting to the world of Rimuru’s. One thing that I wish was easier in the game is the world building section. It’s rather painstakingly long to organize all your buildings into a nice looking town especially after getting your central office and property upgraded. I hope they’ll add some features to make it easier in the future. For now I’m probably going to just focus on the farming and wait for such an update to make my town look nice. Besides this and some very small features that I’m sure will be taken care of at some point (like getting stuck in a battle), the game easily turned out to become one of my favorites regarding. I’m heavily impressed and this game is only 3 months along! Plenty of room to grow and I look forward with extreme eagerness to see it.

Pretty great game
Tue Nov 16 2021 Sukiyaki08

I don’t usually play these types of games but I loved the manga adaptation and anime adaptation and decided to download it. First off your given a lot of stamina from quests and you could play anytime without having to wait. Second, the Secret Skill animations are pretty cool as well as the skill animations. Third, I like how it’s not just the Orginal Story but also some events. Fourth, it has a lot of ways to increase the power of a character like leveling up character, awekening character (or increase the stars), forging weapons, leveling up weapons, evolving weapons, leveling up skills, evolving skills, unlocking health, attack power, defense, and input through ability release, and talking and bonding with the character in your town or interact menu. Fifth, you can build your own town, although you can’t really change the shape of land (only by leveling up the town centre) or add pathways, you can still add building to give you resources and build decorations, think of it like Clash of Clans or Boom Beach without the towers and units. I think overall it’s a great game and although right now it has some bugs and features and characters yet to be added, it’s fun to play a few battles every now and then.

Honestly I love it…

Ignoring the whole Rimuru’s daughter part, I love this game. It’s incredibly entertaining and the battle mechanics are pretty fun. I have kinda reached a spot where I can’t continue, however, because I can’t get my team any stronger so there isn’t much I can do anymore. I’ve also been forced to kinda squeeze all of my buildings together in order to have room for more buildings so I can get my population up so it would be nice if the requirements to expand your area were lower. Even still, I love being able to walk around and talk to people and do requests for them. I also like being able to give them food, but I kinda wish there were more options to interact with them. Like a pat on the head option? Another feature that would be nice to have is an option to ride Ranga around town or even for some kind of mini-game. There’s a few more things that could be added or changed, but all in all it’s a great and entertaining game that I really don’t want to get bored of. So please just give me some more things to do. 💖

summon rates
Tue Nov 30 2021 veldoraT

first thing: the summon rates are absolutely ridiculous. so im currently 9 multi summons into the demon lord rimuru banner and i haven't pulled a any 5 star. im currently 3 multi summons in on the destroyer milim and still no 5 star. currently like 8 multi summons in the veldora banner and i only pulled veldora, which is very cool but i cant pull any copies so he is to weak to go on my team. another 8 multi summons ive put into the diablo banner. only pulled one 5 star and it was a copy of arch golem beretta. this is so discouraging because i physically cant advance my account EP and therfore im a stuck spot and ive done everything i can for my troops but im stuck. i have a friend who is experiencing the exact same issue and his luck is worse than mine, meaning he has pulled even less than me. i spent 80$ on a guaranteed ticket + 1200 gems. i got steel annihilator shion from the ticket, but i received no 5 stars from my summons with the 1200 gems. but my other friend who plays, has pulled a 5 star out of almost every mutli summon. he has pulled every single event character from every banner so far (except the new milim) and even pulled copies. although im happy for him, its extremely discouraging. please fix the rates and i will change my review to 5 star. love the game but summon rates need change please!!!!

Unplayable good game

To begin, of what I was able to play until just recently was a great game appealing to the lovers of the anime series and even those just getting into it via the game. It featured a unique town building aspect alongside being a turn based fighting gacha game, a combination I’ve yet to come across before this, much less do so seamlessly. HOWEVER, it must be duly noted that this game is riddled with bugs, glitches, and crashes. Prior to this, there was a common bug among the community that I experienced where when you were down to your last character in a battle, all actions would become unresponsive and you would have no choice but to restart the app and lose your progress in the dungeon just to go back to doing anything. As of late though, the game has become completely unplayable, crashing every time I attempt to enter a stage. I truly hope these things will be fixed as I believe the gameplay itself is extremely fun and innovative. The team behind the game is working hard as can be seen by the number of patches, but at the moment that has yet to remedy the current state of the game. Wanting to invested a small sum into the games in app purchases, I hope their efforts come through sooner than later as they do have enticing events to partake in. Hoping on the devs 🤞

Love it

I watched the anime of this, and I found the anime very very good. It dried a little bit, but you have to watch it. The game itself is fun. Make sure you pay attention to the tutorial. There’s a lot of stuff I skipped through because I was rushing overall, I love how they switch up the characters, different events, different wardrobes there’s things here that I have not seen in the anime. The only thing I don’t like is there will be a time you’re going to get stuck because you don’t have the highest of luck when it comes to spending your diamonds to basically get the character you need to level up I guess stopped dead right before I can reach the boss because I don’t have the attribute of the same character to boost there levels they need to figure out another way for us to be able to compete in tournaments in PVP. Not everybody luck is high with the draws other than that they can turn in tickets and other stuff but you’re not guaranteed to get the cards you want if that doesn’t bother you we go ahead and play the game.

Good game, not the best though
Thu Jan 27 2022 børėd

I never write reviews but I very much enjoyed the anime and playing this game was a pretty good experience. There are a few problems but I feel like they're easily resolvable for the player to handle. Firstly, the drop system for a 4-Star & 5-Star character is a little too low but thats something that's reversable due to how easy gems are and thats my favorite part about this game, I've been playing for about 16 days and I've easily acquired over $300 (possibly even $500) worth of gems in that amount of time. Secondly, the difficulty spike is a little overbearing especially in Hero's Jubilee but thats understanding since its about skill (and dedication I guess) and it's very easy to get stuck during story missions. I wish abilities were a litte improved but they do provide a noticable difference and the cost of forging / evolving items is a little pricey. That's all I can write for now but it's definitely a fun game with its flaws. (There are a few errors with the subtitles like the occasional mispellled words or a space that wasn't added here and there but those don't really bother me.)

Complex but fun
Mon Nov 29 2021 MoonshineJester

As a Gacha game, you’d expect this game to push you to spend money, but as of now, I haven’t seen any need to spend money. The combat is simple and the AI is very effective for when you want to AFK the combat. The complexity comes in with team building and unit development. There are so many ways to construct a team, whether it be the backup units, the aid units, armour and weapons, town structures, the support unit assigned to the team, etc. This can make it a bit tough to figure out what works best, but it also creates room for freedom in team building. The only complaint I have is that the gameplay slows considerably once your basic town structure reaches a certain point, and you are forced to wait several hours to advance your town further, which also slows down your ability to collect and strengthen units. The game is also crashes fairly frequently and the gameplay is laggy with older technology, but that is more an individual concern than one with the app as a whole. Overall, fun game, a little rough around the edges, but I’m sure those will buff out as things progress.
