RemindMaze

RemindMaze is a video game ideal to train your instant visual memory skills in a funny way. You have to traverse a maze and reach the target before the given time ends up. The maze becomes invisible periodically, that is, it turns from visible to invisible, and then visible again, and then invisible again, and so on. Thus, your memory skills come into place as it is convenient to keep in mind the shape of the maze in order to make progress while it is hidden. You can configure the difficulty level by adjusting the size of the maze, the time given, the shape of the cells, the control method of the character, and the amount of light time during each period. In order to train your memory skills, it is convenient to make it not too easy and not too difficult as well. Succeeding in nearly half of attempts is a good balance to keep motivated and make significant progress. If you keep playing with RemindMaze, then you will have a lot of fun, and will pretty soon realise that your mind is getting stronger in the ability to retain visual information.

The app is free, thus you can download it and play without paying anything. However, not all the options are freely available. The full set of options for the parameters can be in-app-purchased and is very cheap.
