Comments on String.io for Android

★★★★★ Kimberlly Garcia · Feb 7, 2024

I understand bots, and sometimes they don't have brains that sometimes they hit their own tail like 😆😂 well it was easy to win but can you make it a bit harder? Cuz it's too easy it's not like to fare well in real multiplayer I'm losing, but this is easy can you make it multiplayer not bots? Cuz it's not competing any more it's just not fare competing if you don't want multiplayer make the bots a bit smart but btw LOVE THE GAME! 🎮😄

★★★★★ Sabrina Bradley · Nov 13, 2023

Very nice! Fun and I like how I can choose my controls. The ads aren't too bad.

Too Annoying, Too Hard, Too Buggy, Too Many People In A Sever, I Wish You Can Make Your Own Sever, Prop Sever Bro So ANNOYING

★★☆☆☆ G Laustristica Joy Emerald D. · Sep 25, 2024

Ill give this 2 star bc it's the only game that I could play in this phone with the same mechanic but why does the wall install you its very annoying and why do the players keep spawning next to me. It's extremely difficult to play it bc on how many players spawn next to me after I just spawn pls fix this

★☆☆☆☆ Sasha Rose · Dec 2, 2023

Fake. Wants you to believe its multiplayer, but it's not. You are only playing against bots. Change to airplane mode and you get same game play with same players so proof it's fake.

★☆☆☆☆ Akshara Killa · Mar 15, 2025

Yes it's an offline game but imagine you start making a territory and somehow on the internet in between and play for a while ... if someone hits you, and you have a large territory . It will show you an option to watch ad, but it will not show you the ad and make you defeat that game. If we keep the internet on all the time then it will disturb you all the time by showing you long ads this is really disgusting...

★☆☆☆☆ Albert Jumping · Feb 13, 2024

Horrible. APP ADS. Uninstalled. Movement sucks. Not worth playing. Also, this developer is greedy and filled game with ads. Hence, APP ADS. AVOID
