Ferrowake: River Slalom Racing

Top-down river slalom: read a current you can see, take every gate in order, red ones upstream, and race the ghost of your best run. Eight courses with gold, silver and bronze times. Free, no ads, no tracking; keyboard or touch.

Ferrowake is a top-down river slalom against the clock. The river pushes you all the time: fast water in the middle, slack water by the banks and behind rocks.

Take every gate in order, green ones downstream and red ones upstream against the current, and race the ghost of your best run.

• Current you can see: a flow field drawn as drifting streaks, with eddies behind rocks.
• Boat physics: momentum, a keel that resists sliding sideways, back paddling and ferry gliding.
• Upstream gates: red gates must be passed against the current, as in real slalom.
• 8 courses: from Mill Run to Ferrowake Gorge, each longer, faster and rockier.
• Medals and ghost: gold, silver and bronze times per course and a saved ghost of your best run.
• Keyboard or touch: arrows or WASD, or hold and drag on a touchscreen.
