SudokuSquare
Read full descriptionHide full description
SudokuSquare is the first game with a whole new concept of numbers. SudokuSquare is inspired by Sudoku, but it completely upsets the rules. One of all is the use of two numbers per cell, and this makes the gameplay all new but above all, more compelling. Try it and the other number games will seem like history. In SudokuSquare you can play with three different difficulties, plus a bonus, the Advanced one. This mode is only accessible after completing a certain number of grids. This is because in the advanced mode, new rules will be introduced, to make the game more and more compelling, and if you know how to play, you will have even more fun. Also in SudokuSquare you will have the opportunity to share your results in the individual difficulties and in the total world ranking, so you can compete and have fun with all your friends. SudokuSquare will revolutionize the concept of numeric games.

Like your muscles, your brain needs regular workouts to stay in shape. Download this app and use it every day to help you stay sharp. You can improve your brain’s abilities. With regular training the brain is able to form new neural connections. Cognitive Boost can be played by all ages, toddlers through seniors. Because each game is short, it is ideal for playing while waiting for a meeting, or for other events. It is a good "calmer downer" if the person for whom you are waiting is late. Because it is highly intuitive, language skills are not required. Emojis tell you visually if you got a correct or wrong answer. The objects used for the game are based on standard emojis, but their looks have been re-imagined by the students and faculty of a historic European design university. While the game resembles the popular "memory match" games it is unique. It has hundreds of emojis that are displayed randomly. To play, you first memorize two to twenty images at a time, and then pick each original image from a "lineup" that has two new images. Start at two images at a time. As you gain momentum increase the number. Psychologists say that, on the average, without training, a person can get to seven. See how you measure up! Another challenge is increasing the rotation speed of the "multiple choice" answers. The objects rotate in three dimensions, all in different directions requiring observation, timing and memory. You can start the movement at a low speed, and as you get experience move up to a higher level. The app is complete. It is free. There are no in-app purchases. There is a button in the app that allows you to make a voluntary contribution of any amount to Parkinson’s Disease(PD) research. There is currently not a cure for PD, just problematic treatments. The button provides a direct link to the research center’s computer. The app was written as a fundraiser, by a software engineer, with 58 years of experience in IT, who has PD. Take part in the search for a cure! Download the program to get started with your memory training!

Verdict
The clearest difference is in-app purchases: Cognitive Boost at none against SudokuSquare's 3. Cognitive Boost also leads on ads (none vs shown) and update cadence (every 11 days vs every 4 months). SudokuSquare's advantage is device support (3 vs 1). On price and iOS requirement there is nothing between them.
