Freex Island is a pixel-art island split into 1,000,000 plots, from small 1 x 1 lots in the Outskirts to extra large ones downtown. Sign in and the island gives you one small plot for free, marked with your pixel character. Every other plot costs Freex Coins, the coins you collect by playing the games on GAMEFREEX.
There are 125 buildings to put on a plot, from a small house to a stadium, each with five levels. Rarer ones unlock as your island level goes up, and that level comes from the coins you have spent on the island. You can hold up to 50 plots, list one for other players to buy, or sell it back to the island for half of what it cost.
Plots and buildings are in-game items. Like Freex Coins, they have no money value and stay on GAMEFREEX. When every plot is taken, the next island opens.
