Peg Solitaire
Jump a peg over its neighbour into an empty hole and remove the peg you jumped. Leave exactly one peg, in the centre.
Jump pegs until one is left. 32 pegs left / 0 jumps
How to play
Tap the peg you want to move and the holes it can jump to are marked. Tap one: the peg jumps over its neighbour and the jumped peg is removed. Pegs jump along rows and columns only (the triangle board also allows diagonals). Leaving the last peg in the centre is a perfect finish. Back works as many times as you like. The small triangle board is a good warm-up.

On the 33-hole cross board, starting with only the centre empty, 32 pegs can be reduced to one in 31 jumps, and the program on this site found and checked a way to leave that last peg in the centre. On the 15-hole triangle, whichever single hole you empty first, you can finish with one peg in 13 jumps; all 15 starting holes were checked. From a middle position, the Hint searches to tell you whether a finish is possible. If it cannot finish the search in time, it says so honestly.
