Neuro Defend Different Online Memory Games for Adults There are thousands of memory-based games that you can play to improve your memory. Word games like word bubbles, for instance, are known to help improve memory strength. Other online word games that you can include are Scrabble and crossword puzzles. The best games are those wherein the brain is forced to intercept two signals at the same time: a visual signal and an aural one. For example, in a game like the color, you receive visual and aural signals. You are supposed to recognize the colors that are called out, but the name of these colors is different from the color in which they are written. Therefore, the signals can be confusing. It is up to the player to intercept the correct signal and play according to the rules.
