Na Soft has created a pair of free games in what could be described as a cross between the simulation and strategy genres. In addition, they've developed a donationware game called Dotris in the general theme of Tetris, to be played on braille displays.
From their website:
There is no charge for downloading Dotris but it is not free. Users are expected to make a donation of how much they value the game at. The donations made by users will not go to N A Soft or anyone associated with it. The donations are to be given via the www.NDAdamson.com website, the home of N A Soft, to support the ClearVision Children’s Library who encourage the use and learning of Braille by turning print books for children in to Braille.
Because of the philanthropic nature of the project and the damage that could be caused by making the game available through unofficial channels, the archive does not host Dotris. We wish Na Soft great success, and hope that the time and energy they've put into the game will make a difference for children everywhere.
