Directional Sweeping Lab

Start with eight visual challenges, then work through six advanced team decisions.

New to sweeping? Start with the beginner guide. · Explore advanced sweeping practice.

This is a visual learning game, not a stone-physics simulator. Brush controls demonstrate geometry, not a guaranteed change in curl. Actual directional effects need coach-led testing with your equipment and ice.

Challenge 1 of 8

Only the controls needed for the current challenge are active. You can pause the motion at any time.

Angle is measured from screen-horizontal. Double arrows show back-and-forth stroke direction. The pad stays flat and keeps its orientation while the stroke changes. These drawings are not a prescribed sweeping technique.

Choose an answer. You can retry any challenge.

Take the lesson onto real ice with a coach. Keep safe footing and the full pad flat. Follow your event’s rules. World Curling’s September 2026 policy prohibits push-dominated single strokes, side/edge-only contact and techniques intended to slow a stone. This game does not award coaching certification.

Advanced Sweeping Decisions

Six authored situations. Decide what to communicate, which evidence to trust and when to change the plan.

These scenarios assume the conditions described. They do not predict a real stone’s path or prescribe an equipment-independent sweeping technique.
