No complicated tutorials, it's ready to play right away. Just remember one principle: no two items in the same row or column can be the same. As you progress through the levels, the grid will get larger and the number of colors will increase. Challenge your limits and break your own records. Daily check-ins give you extra chances; miss them and you'll have to wait until tomorrow. This design gives you a reason to come back and play every day, helping you form a good habit.
