Frequently asked questions
Is PolyGround real-money gambling?
No. PolyGround uses play money only. Coins and XP are virtual, hold no real-world monetary value, and can never be purchased, cashed out, or exchanged for anything of value. There is no deposit, no withdrawal, and no wagering.
Do I need crypto or a wallet?
No. There is no cryptocurrency, blockchain, or Web3 functionality anywhere in the app. You sign in as a guest or with Google and start with 1,500 free coins.
What is a prediction market?
A prediction market turns a question about the future into a price. If a market trades at 68%, the crowd collectively rates that outcome as 68% likely. PolyGround shows you those probability swings and lets you make calls against them with virtual coins.
What happens if I run out of coins?
Nothing permanent. Bankruptcy Respawn refills your stack after a cooldown, and you can also earn coins from daily streaks, quests and optional rewarded ads.
Is it free?
Yes, completely. There are no in-app purchases, because there is nothing to buy — coins have no monetary value.
What platforms is it on?
PolyGround is available on Android via Google Play.
