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 French: 36 pegs in 37 holes, with c1 empty. Finish with the sole peg at e1. A central vacancy cannot finish with one peg under ordinary orthogonal jumps; this edition adds neither diagonal jumps nor replacement pegs.
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 an orthogonal empty landing beyond one peg; inspect the target hole.
Worked example
The classic vacancy is c1 and the target is e1. Do not substitute a central vacancy or add diagonal jumps to imitate the English board.
