Ice Breaker: Platinum
Get a 15x column combo in Ice Storm Mode

The achievement is hard because of 2 reasons:
1) The random nature of column-combo gem combinations.
2) Very little time between breaking 2 columns.

The guide will not provide a guaranteed way to obtain the achievement. There is just no guaranteed way. The guide instead will give tips which would be of a help to anyone trying this achievement.

The column combo (CC for shortness) is a destruction ice columns within small time. The combo increases if you destroyed an ice column and amount of time passed since previous destroyed column is less than some amount.

The approx. amount of time between columns: 2-2.5 seconds. That is small and big at the same time.

An ice column can be destroyed by:
1) Making a vertical match in the same column as a colum itself.
2) Triggering star gem in the same column.

Effectively, that means that you must search for vertical matches and clear them within 2 seconds of each other.

A combo does NOT ends if you make a match that does not destroys a column for as long as you destroy them within 2 seconds of each other. That means that you can make horizontal match or trigger rainbow cube and still be in combo.

So, you are going to get this achievement. Here are my tips:
1) Use WASD instead of mouse to make matches. It increases your matching speed by about 1.4 times. If you are bad with keyboard, i highly recommend you to try.
2) If you don't make good enough combo before x3 multiplier, restart. double sized columns are lots of easier to destroy and you need 1 avaliable match per each 2 columns to sucessfully continue the combo. If you are on bigger multiplier, amount of columns is about the same, but they are only 1 column wide.
3) Remain calm. If you made it to x14 but you can't find a match, don't panic. Even if it seems that the combo is over, keep searching. I made my last match PURELY by staying calm. I was a nanosecond before failure.
4) Chains are your WORST friends. Chains require a bit more brain power to find matches, and sometimes they simply change the field way too much. Also, a big chain takes lots of time. The chain may destroy some columns on its own however.
5) Due to 4), don't try to create explosive gems and use them. They are not worth it.
6) If there are more than one match possible for an ice column to be destroyed, choose the one that is higher/the one that will not alter other matches you see. Also, triggering a match in lower part of screen can create a chain reation and screw you.
7) You have about 2-2.5 seconds between each column. USE these. If you see a match immediately after another one, don't insta click it. Use remaining time to see for matches in columns with other ice columns. If none are present, look for matches in columns where you think an ice will rise. That highly slows down requred pace of matches.
8) Remember: an ice will not start rising where it just was. If you have three 2-col. wide ice columns, then if you destroy one, another will rise in space that was empty before.
9) The amount of time that it takes for star gem/rainbow cube animation to finish is not accounted into CC.
10) For the reason above, if you see that after your current match, no more CC matches are avalible, and you got a cube around, trigger the cube. First, it will refresh the field. While the refreshing is done, you have some time to rest. However, while gems fall in place its hard to seek matches, so cubes are double edged swords.
11) Avoid triggering matches, if gems you swap will create 2 matches and you only destroy one column total. If possible to trigger them separately, do so and you have 1 extra match.

Make a move, then printscreen and paste to "mspaint" for example. while bejew window is not active it doesn't count time. so you can calm down and look upon situation on the table.
once you decided to make a move you just open bejew window and make that move. and printscreen again. and so on and on untill success.
Problem is there's not always good move on a table
