Works on phones and computers

You helm a small sailboat among low-poly islands, steering with the rudder and easing or tightening the sail as the wind shifts. The daily race sets a new shared course each day, with a countdown to the start line and ghost boats from earlier runs to race against, and High Sea sends you through big open-ocean swells to collect buoys while the wind and waves build. Free sailing puts you in an open sea with other players, and a tutorial covers steering, sail trim and racing. Works on phones and computers.

How the creator made it

The creator made the first version with Claude 3.5 Sonnet. They say they developed it mostly with Codex 5.x models over the following year, then used Grok 4.5 in Cursor for more work on the game. They later added Takram's volumetric clouds to the Three.js sky and tuned how much cloud detail to show at each graphics setting.
