Based on a three by three grid, the goal in Galaxy is to get from one planet surrounded by black holes to the reverse: one black hole surrounded by planets. Each time you click on a planet all adjacent spaces swap their states. This is the biggest Pronto game ever, with over 500 panels, 2,800 buttons and 5,300 frames! Thus, Galaxy will only work with TSU2000, RU940 and RC5000i models. Wondering what to do with all that memory on your 2mb remote? Well, this will occupy 37% of a TSU2000 and 26% of an RU940 or RC5000i. Enjoy!
