Teach the buddy

Your buddy has a question. Show a move, see what happens, and explain your idea. Mistakes are welcome; there is no timer.

Learning comfort controls

Letter, shape, dot, and ring markers stay visible. Enlarged boards can be scrolled horizontally.

Show Sprout the danger

Sprout: "I only looked at my red counters. Can you show me what Yellow might do next?"

You are Red (R). Stop Yellow's next winning drop, then explain your idea.

Explore this read-only board with the arrow keys. Use the named move choices to show your buddy an idea. A gold outline marks the last move.

Red (R) moves first · Yellow (Y) moves second.
