There're lower-class competitive players about Puyo-Pop in the world. They haven't yet aquired the ability to make higher than12 chains at any time while playing matches.
Even those players attempt to teach beginners how to create the form of stairs/hook and the way of assessing the situation of enemy's field.
That's too funny.
In fact, there're too many web sites where players wrote ways to create chains such as stairs or hook for beginners on their own sites; Therefore, I recommend the following websites as a starting point to anyone that gets interested in how to create more than 1 chain.
