A very unique take on the old Columns genre (and it's FREE)! – NumberGem - free addictive match number puzzle game Review

Sure, as a FREE app it is sponsored by ads (most of which appear to be Japanese or some other Asian language with English words thrown in randomly), but they're just along the bottom and are very non-intrusive (as a swipe and tap based game, there is never any need to get anywhere close to the banner and accidentally click out of the game). Once past that it is a great FREE app. The game's main unique twist is that each of those different colored blocks are not simply a different grouping, but have their own unique requirement to clear them. Bring any two yellow blocks together and they're out of your hair but if you want to clear out those cyan blocks you'll need to link at least EIGHT of them together. As is standard in "Match 3" (not exactly appropriate in this case, but you know what I mean), if you can group together more than required or cause a grouping of the blocks to occur as a reaction to another group being cleared, there are much bigger points involved.
