Is the 50% increased chance actually a 25%+ chance every upgrade? I can’t tell,also this is just to clarify. ### 5/5 — Here’s some info for the maps *2022-09-29, version 1.9.7* For those of you who didn’t know you can actually tap the red bird on the maps and you will get a random reward which can be:gems or scrap! ### 5/5 — Couldn’t be better *2022-04-03, version 1.9.7* A while ago, I downloaded castle fusion on a different device. That device stopped working and so I decided to get this again. I really enjoy playing it and the story is great. I got to a pretty far point on my old device and I can’t wait to get back to that point! ### 5/5 — Love the game but *2021-12-05, version 1.9.7* I cannot make purchases in the market. Get “unavailable. This item could not be loaded. Try restarting your game.” What the heck? You’d think every possible solution would have been attempted so that I could spend money. Please advise. ### 5/5 — The best tower defense game *2021-07-19, version 1.9.2* I played this once and I read it but then got bored of it so I deleted it and I installed it on a new device and then I just can’t stop playing it now it’s just so much fun I’m already on the second world spoiler I guess you could say second one whatever it is it’s just so good I can’t stop playing map creator keep on dude this kind of stuff it’s super good ### 5/5 — This is my favorite game *2021-04-10, version 1.80* I like that this app is like super good graphics and it looks super realistic and it’s like if you’re in a VR movie but in your phone. so the graphics are really good and I like that all the weapons have to reload but it’s kind of weird because when you’re in the catapult and you click it it like doesn’t even need to reload and it’s at the bottom and it’s just flinging it so can you please fix this weird problem ### 5/5 — More should be added *2021-03-07, version 1.80* I would give it 4 if it had more action like maybe mini games for prizes or more attackers and zones all of this would be 5 star then maybe lower the price for new hero’s but other than that it’s good ### 5/5 — The best game ever *2021-03-01, version 1.80* There are towers goblins and you can fight and collect treasure when you upgrade you get the thing you upgraded and then it shows up on screen and tells you how how many seconds it shoots. ### 5/5 — Great Game So Far *2020-12-07, version 1.80* I have been playing this game for only 4 hours but in that time it has been pretty fun! Just as I start to become bored with the game and go to turn it off and start one of my other mobile games this games adds in another part/game play and it hooks me back in for another 45 minutes - 1 hour. ### 5/5 — Great *2020-07-24, version 1.65* Great game but your should be able to get a upgrade where you are able to get a level up Tower let’s say ballista to the triple ballista because really hard to get anything done when you keep call towers when you were all Gatling Canon on your Castle please reply back ## Frequently asked questions about Castle Fusion Idle Clicker ### What is Castle Fusion Idle Clicker?
