Play safe
Chat, spending, age and breaks.
Six games, six different answers to who can talk to you and what costs money.

Who can talk to you
Skribbl.io is the only one of the six with open text chat, and in a public room it is open to strangers. Players can mute, report and vote to kick, and a private room keeps out anyone without the link.
StarBlast offers 16 preset phrases and no typing. Soccer Random, PolyTrack, Paint to Hide! and Mini Golf Club showed no chat when we played. In PolyTrack only people with your code can join at all.
What costs money
None of the six sells paid random items. Mini Golf Club sells coin packs from 1.99 USD to 49.99 USD, spent on hats and trails at fixed prices. StarBlast's Elite Commander Pass removes adverts. The other four sell nothing we could find.
All six show adverts on CrazyGames, and Mini Golf Club pays out coins for watching short ones. If a child plays, agree before the first match whether real money is ever spent.
Age rules
CrazyGames' terms say you may not use crazygames.com if you are under 13, and send younger players to kids.crazygames.com. Its page for parents adds that some games offer in-game purchases.
Three games have their own PEGI rating in an official store: Soccer Random (PEGI 3, Google Play), PolyTrack (PEGI 3, Google Play and Microsoft Store) and Mini Golf Club (PEGI 3 with in-game purchases, Microsoft Store). We found none for Paint to Hide!, Skribbl.io or StarBlast.
Match length and breaks
Short matches make it easy to play one more. A Soccer Random match lasts a few minutes and a Mini Golf Club match three holes, while a StarBlast session has no fixed end. Deciding the number of matches before starting works better than watching the clock.
Reporting a problem
Report a player inside the game where it allows it, as Skribbl.io does. Problems with a game itself go to CrazyGames through the report button under each game. Mistakes on this site go to hello@lobbycove.com.
