Comments on Fireline Merge Defense 3D for Android

★★★★★ jean meteus · Feb 21, 2023

This is the BEST, I already in the millions within 3 mins of playing this and all turrets are powerful

★★★★★ Ayden Kotze · May 21, 2022

Reached lvl 50. Have a lvl 11 tower. I can spawn lvl 3 towers. Have more than 200 Million coins. Have 60 gems. I recommend download this game. Also, when you're playing the game i recommend to turn of your Wi-Fi / internet. Enjoy. Spoiler alert, lvl 10 tower is a peashooter. Difficulty for me is moderate

★★★★★ Rupa Roy · Apr 29, 2024

It's the best game ever when I was a kid I played this game a lot I like this game, so I will give 5 stars

★☆☆☆☆ Ryan Riopel · Aug 26, 2021

Ads, pop-ups, popup ads, more ads, more pop-ups, and some gameplay, then more adds and pop-ups followed by more popup ads. On average every 30 seconds is a mandatory 30-second ad. In between pop-ups to watch ads for stuff that would take you less time to play then watch for reward. If your tablets on airplane it takes away mandatory ads, but you can't get freebies when you want them. Don't want to turn my phone to airplane mode to play. (Negative)6/5.

★☆☆☆☆ Dov Jur · Jul 30, 2021

BAD! Stages are too hard, 2nd, too many ads when I want free rewards, 3rd, my dad doesn't play this game, not making the stages at least like other td games is bad. BAD!
