The games creators, Spryfox, have also made games such as SteamBirds survival and Bunni: how we first met. Each game they have created so far has been of a different genre and Triple Town is their puzzler.
Warning: may contain bears!
Bears are basically the enemy of the game. They wander around the town as you're trying to build it up and the only way to get rid of them is to trap them, which turns each separate bear into a gravestone. Three gravestones make a church, which is worth a fair few points.
There are also Ninja bears, who can teleport between blank spaces on the board and are generally a nuisance.
Now, I recently re-played Triple Town. They've added new graphics and a better bonus for matching more than three items (they used to just make a prettier item that was worth slightly more).
Anyway, Triple Town is a brilliant game so I suggest you play it! After all, free games are awesome!
