One board · one peg left
Peg Solitaire
Jump pegs over their neighbours to remove them, one jump at a time, until a single peg is left. Best of all: leave it in the very centre.
Tap a peg, then tap the empty hole two steps away (the jumped peg is removed). Jumps are horizontal/vertical only. Finishing with one peg in the center of the English board is the perfect game.
