Triangle · Solutions

Follow one verified route from the listed vacancy to the marked target. Each line is one jump: the first coordinate is the moving peg and the second is the empty landing hole. Pause, step backwards, or select a jump in the list. This replay demonstrates the default opening, not a solution to every position.

The 15-hole triangle has five rows, from one to five holes. Empty a1 and return the survivor to a1 in 13 jumps. Use all six lattice directions. The b3 complement and a1-to-b3 target are impossible.
