To use Gibgab, first pick a category from one of the cards. Then press the center button on the game board to turn it on. Once the lights light up, quickly say a word that matches the category and press your button to make your lights move towards your opponent. Your opponent then has to do the same to get their lights moving back. You can set the speed of the lights according to your preference - 2 seconds per light, 1.5 seconds per light, or 1 second per light. When playing, make sure to think fast and be ready to speak up. As for maintenance, keep the game in a dry place and avoid dropping it. If the batteries need replacing, use the appropriate type and follow the instructions inside the battery compartment. Have fun with GibGab!
