Do you remember the game "Remember 4 colours", where colours were randomly displayed on the computer?
The idea was developed for the current day and in particular was adapted for iPhones.
This game requires active involvement rather than just a boring and passive use of colours. Random directions are possible, control of which can be mastered by a player having little practice and speed. This enjoyable game is perfect for anyone who would like to test their brain, intelligence and speed of movement.
