Made up from scratch

Games

Games that did not exist until Flynn invented them. These three run on Planet Play, a portal of learning games for kids — built, playable, and still getting better.

Guardian City: an isometric seaside map with power, water and homes placed, and a flood forecast warning
Playable Planet Play Ages 6–11

Guardian City

Be the guardian mayor. Grow a city inland, by the sea or up in the snowy mountains, then read the forecast and build the right defence — levees, shelters, fire stations, bunkers — before floods, tsunamis and avalanches sweep through. Keep everyone safe and watch the city bounce back.

Disaster De-Defense: an earthquake level asking what to do first, with a danger meter and three choices
Playable Planet Play Ages 6–11

Disaster De-Defense

Nine real disasters and one right move to survive each of them. Earthquakes, floods, tsunamis, wildfires and more — do the real-life safe thing before the danger meter runs out. Play the story Adventure, an endless Survival run, or a no-danger Creative sandbox.
