I've uploaded a playable prototype of my current project called Osiron, which can be found here.
There are three game modes (only 2 are playable in this prototype):
Osiron Classic - The original 2-player Osiron game. Rules can be found here. On your turn, click one of your pieces to select it, then click one of your opponents pieces to swap them.
Osiron's Dusk to Dawn - A single player puzzle-type game, with a similar feel to a Rubik's Cube. The goal is to create the inverse of the design's color scheme in as few moves as possible. The end gameboard result should find all original dark playing pieces now occupied by light colored ones, and all original light playing pieces now occupied by dark colored ones. Click the center of a circle to select it, move the mouse left and right to rotate it, and click to lock the circle in position.
Osiron's Prism - Not yet available.
I've been working on this for less than a week, so it's still a major work-in-progress, and there's still a lot more work to be done on it. The final version will feature all three game modes, many different board layouts, selectable boards and pieces, and more. If you have any suggestions or comments, or found any bugs, please leave a comment or PM me.
