The game known as "Peg Solitaire" was popular throughout Europe in the 1800s. It is said the game was invented by a prisoner in the Bastille. Bastille Solitaire is a modern improved realization of this game.

Bastille Solitaire has two types of levels: puzzle levels (like in the original Peg Solitaire) and strategy levels. The goal of the puzzle levels is to remove all the pegs but one. The goal of the strategy levels is to remove as many pegs as you can.

A peg can jump over any adjacent peg if there is an empty space on the other side. As a result of the jump the latter peg is removed. Only horizontal and vertical jumps are allowed. Click the peg you want to jump. Then click the space where this peg has to jump.
