HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (37 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Is this an online game??

One day, my daughter asked for String.io and I was like sure so I downloaded it for her and I found people’s names that actually look like real life people they act a little bit weird so I don’t think this is a safe game for four and under or five and under if your child is five or six then delete the game immediately

★★★★★May 2, 2024
Fofo

O jogo é legal, mas precisa melhor a mobilidade do jogo, e melhorar o gráfico

★★★★★Apr 20, 2024
Great game but everyone goes for me

When I get good everyone comes ands steals my space and try’s to kill me

★★★★★Apr 4, 2024
I think it’s online game

It’s a challenge every five seconds 10 people will appear around you aggressively eating you and charging at you and then they’ll come back so it’s almost impossible to play this game and get 50% of map I like how fast you can expand but this game is like really really really really really hard

★★★★★Mar 12, 2024
Annoying ads

When you die, you get asked to view an advertisement to get a second life. Once the ad is finished, you can’t exit the window to go back to the game.
