Five in a Row puzzles
Five in a Row puzzles are forcing wins in two, three or four moves. Every move of the solution makes a four, so the defence is forced, and the engine checked that nothing faster wins and that the key move is the only quick start.

Easy
#1–14 · Find the stone that makes an open four, or a four plus a second four, in one move.
Medium
#15–27 · Look for a four that forces a block in a useful place; the next four should land next to it and create two threats.
Hard
#28–40 · Four-move wins chain fours across two or three directions. Try each four you can make and see where the forced block sends the defence.
