SoliOne HD is a challenge game board for iPad based on the classic peg solitaire game (also known as solitaire, resta-um or brainvita in some countries).

The game starts with a ball on each hole, except one, and the objective is to leave just one ball on the board.

To play you select a ball and jump orthogonally over an adjacent one into an empty hole. The jumped ball is removed from the board and the selected ball is moved to the new position.

There are six options of board:
- English - with 33 holes
- European - with 37 holes
- Square - with 36 holes
- Germany - with 45 holes
- Diamond - with 41 holes
- Asymmetrical - with 39 holes

You can also select the color of the balls and turn on/off the sound.

This game offers a clean and modern design.
