This is a place where all mobile sandbox game players can come together to find the good stuff
the best one so far:
nextbots in playground sandbox
it is not just about nextbots ok.
it is way better, with a wide variety of enemies and allies fights will be amazing! it has gadgets and cars and so many cool maps so you will never run out of fun.
take my word dude or lady
the other games by HOOKAH GAMES are amazing as well. they are all sandbox games. try White Spirt Games also. that developer has amazing sandbox games
dmod is good too. it is exactly like Gary's Mod. With less stuff though.
i am also documenting updates in some sandbox games too.
