-To the beginners living in other countries-
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
(For English speakers)http://www.spacelan.ne.jp/~shiroma/ips/info/chain/
(By players in Ishikawa Prefecture)http://alg-d.com/game/puyo/
(For beginners and lower-class players)http://www.geocities.jp/mipuyon/
(a little bit old information)
(By one of my net-friends, Mimikaki)http://www43.atpages.jp/clocklaboratory/game/puyo/puyo_title.html
(For lower-class players)
It's not difficult to create less than 12 chains, but making longer than 12 chains suddenly become difficult for lower-class players
13,14,15,16,17,18....and 19! (20 in only SUN)
You should keep these matters in your own minds.
