Working as of June 16, 2018.
So I was checking out the different parties that were going on around OurWorld and when I joined one of them I saw some people talking about a new flow game.
The game is called “William The Runner“
Step 1: Find “William The Runner”, it should be located in Arcade.
Step 2: Start the game and claim your first achievement (100 coins) and use it on HP, Attack, Regeneration and/or Attack Cooldown as your starter.
Step 3: You can leave it as is and start earning flow! Do not worry about losing your health in game, you restart back from 4 waves. Say if you were at 15, you go to 11th
The best way to maximize your flow gain is to fully level up your character’s HP, Regeneration, and Attack Cool down and that way your character can make it up to the higher waves. Higher waves means more enemies, which means more hits, which means more flow! It is recommended you only max out those 3 so your character can make it far, but not to the very end. If you maximize those 3 skills then you can go AFK and let the flow build up!
The amount of flow you get will also vary on your flow boost percentage.
Secret ourWorld Cheats 
it is working !! u just havta refresh it . there maybe a prob with a specific browser or somethin
Doesn’t work from today evening.
mine is working just fine
hey , did ourworld stop to get flows from this game ? cause ow stopped suddenly and i cant get flows from it again >_<
okay guys so it will stop working after you earn i wanna say 1500 flow. you just have to open an incognito window and log back into your character and start the game up again. it will make you restart every time you refresh or log out, but it lets you gain more flow.
yeah i left it overnight and the flow went up to 80 only then it stopped… :(
you have to refresh after an hour and a half
Yeah, just like every other flow game, you need to refresh every hour and a half. But after using this game for a while, you’ll stop earning flow completely. To fix this, you can either do it again in a private window, or you can clear that browser of the cookies (Only do this on a browser you never or rarely use). But keep in mind that each time you will need to restart from the beginning of the game.
doesnt work anymore
Yeah… hasn’t been working for a while
It does work but there have been reports of it stopping after using it for a while, its a small chance though. To fix it just try using a different browser :)
actually nevermind it works
It works for me… I mean I have an 832% flow boost though… Find me on ourworld at xxstarxx76
