Comments on Slime Castle — Idle TD Game for Android

★★★★★ Jason Potter · Oct 3, 2026
Fun entertaining something to help pass the time while I'm working on some other stuff
★★★★☆ Patrick Greenway · Jul 4, 2026
I and my gf have been playing this for over a month, and we're loving it, however, every other slime but Tarranis have an artifact. I saved up for him and have him upgraded but I can't get an artifact that's made for him unlike every other slime
★★★★☆ r t · Oct 19, 2026
This is not an actual Tower Defense game, don't be fooled. Also, it's extremely p2w, don't be fooled by the automated messages claiming its f2p, or "f2p friendly". The devs have antagonized their own player base for several months now, and it's looking like they are trying to sabotage their own game. Don't recommend you waste your time with it.
★☆☆☆☆ randall hughes · Jun 29, 2026
Any and all competive things in game is all about how much money you spend. Attack trading is supposed to tell what you need to know with info of attack, speed, and life. I was defeated by attack rated attack 4,000 less, attack 150k less, speed 1.5 less, life 150k less. But they had one of the most expensive slimes you can buy.
★☆☆☆☆ Lourens Van Burick · Oct 9, 2026
I have returned to the game after taking a long break from playing it and returned and would love to restart the game from scratch with nothing but with the things and slimes you start the game for the first time, and I don't mind rebuying all in-app-purchases with real money again, as long as I can restart the game from scratch with only the starting stuff with 0 xp. Is there a way to reset your account to a new account please?
★☆☆☆☆ Chaz Kraiza · Oct 22, 2026
Too many hackers these days. Soooo many people are hacking the game and your team in the arena will have 71 million strength, and then you'll get your butt absolutely handed to you by the 12 million startup account in the arena and throw your arena win numbers off. It's really ruining the games multiplayer aspects.
