Chain Factor Clone

**HOW TO PLAY**

Select a row in which you want to drop a disc. A disc may have a number between 1 and 7. 

A disc will be removed if its vertical or horizontal chain's count is equal to it's number.

EX : 7 5 3 4  = > 4 will be removed because chain of length 4. Then 3 will be removed because the new chain has length of 3. 7 and 5 remain.

There will de discs with no number. You have to remove discs that are adjacent to them to reveal them. 2 adjacent removals will show the discs's number.

Every 20 turns, a row of unknown discs will appear from the bottom. Each level, the number of turns before the new row will decrease by 1 until reaching 5 turns per row
