Before I'd also tried squinty Josh's anti-suppression solitair game. He applied the right colors in order to make his solitair game 'uncheatable', meaning that you are forced to use both eyes. So similarly I made the Tetris blocks look red and blue and made sure the background was black so you can't even cheat using the edges of the blocks. Of course, red green anaglyph glasses are required.

For some people the black background has proven to be stressful to start out with. Because of this a more tech-savvy VT friend of mine named Aaron added a couple of sliders at the top enabling you to adjust the background color to alleviate frustrations a little and ease into the game.

It's definitely good anti-suppression practice. I'm still very insecure about positioning my blocks!
To keep things interesting and visually more challenging you might want to turn around your glasses every so often (or interchange the colors in the html file). That way the eyes switch color and the amblyopic eye takes on different roles within the game.

There's no better feeling in the world than knowing that your hard work is being appreciated. In addition, I can use some encouragement and financial support to do an even better job and get through my own visual rehabilitation.
