Rules & objective
Select a peg, jump over one adjacent peg into the empty hole immediately beyond, and remove the jumped peg. English and French boards allow only horizontal and vertical jumps; the triangle allows its three lattice axes.
Classic English: 32 pegs in 33 holes, with central d4 empty. Finish with the sole peg at d4.
Generated challenges have three difficulties and accept a sole peg in any hole. New and Restart restore the same fixed classic start. In challenges, New changes the puzzle and Restart keeps it. Hint highlights one verified jump toward the target without playing it. Away from the known solution, search is bounded; no result does not prove impossibility. Each jump counts separately, including consecutive jumps by the same peg.
Controls
Click or tap a peg, then a legal empty destination hole to jump. Select a peg and the empty hole beyond one adjacent peg, then confirm the jump.
Worked example
Jump over one adjacent peg into the empty hole immediately beyond it, removing that peg. The classic start requires the final peg at central d4.
