Comments on Grim Defender: Castle Defense for Android
★★★★☆Dustin· Jan 27, 2026
A absolutely stellar game. there's no real right way on how to play. Just have some sort of splash damage and your set... however. The only complaint is that: for needing dark gold for pretty much everything... it's super rare. I want the option to at least trade something FOR dark gold. Not trade dark gold for something else. And it's not like you need a small amount of it for everything too. It can get extreme. May update this later as I play. But for now. That's my rating.
★★★★★Darren Mersnick· Jun 30, 2026
This is probably one of my favorite mobile games just for its simplicity and the fact it doesn't shove ads in your face even in 2026. It's straightforward, and it doesn't just hand you the win you actually have to try a little bit
★★★★☆Derek B.· Aug 25, 2025
Good game. One problem, though: you need to get to stage 40 at least to unlock the auto turret, there's only one, and you also need 10 dark gold (premium currency) plus 125 rubies plus 150k gold. It will take you forever to get that much dark gold, regular gold and rubies. You'll have to withstand the horribly tedious nature of aiming with your finger forever......unless you pay up, of course! Buy the one auto turret to give your hand a break, for only $30! (or spend days grinding).
★☆☆☆☆Joseph Accavallo· Jul 20, 2026
This game is garbage it dost give you enough of anything to upgrade also don't give you to option to upgrade so it's not like you can grind for them every single enemy has just enough health to be an issue you get hard stuck for days and days on the same level just hoping and praying for good rng, and it never comes almost every upgrade in the entire game is both locked behind the 30th or 40th level which is crazy when they stick you behind levels for days at a time and "dark gold"
★☆☆☆☆Joel Davidoff· Oct 7, 2026
Progress is based entirely on an ultra low drop rate currency ("dark gold") which is needed to buy basically everything to help progress. Upgrades are extremely minor in effect, especially those that don't cost dark gold - getting very expensive very fast and usually not even able to push you past a single level. There's "player vs player" modes which can give dark gold, except the "player" is an AI, and always set to be above your level, so you lose. 100% designed to make you pay for dark gold.

I like the game, but obtaining black crystals has gotten ridiculous. I received one from killing the level 620 boss and killed the level 630 boss 10 times and still no black crystal until I finally got the next crystal after beating the boss at 640. If you want to improve your game, you need to add more black crystals, especially if a player has the level 2 holy grail to increase crystals.
