Welcome to Gecko Interiors, a fun and colourful gift and homewares store based in tropical North Queensland, Australia. . Whether you're a local shopping from home, or dropped into my store while on a recent holiday to Townsville (with no room left to take everything back in your suitcase! ), let us take care of delivering to you.
Dam Filler is an educational game ideal for homeschooling. This is a locally produced board game, based around Australian weather and teaches about the Dry Tropics including STEM concepts of Wind Speed, Direction, Relative Humidity and Pressure Systems. You don't need to know anything about that to play, you just play and learn as you go. The infographic left shows the steps each player takes during their turn. Watch the video on how to play.
