It's a puzzle game with puzzle mechanics, but without actual puzzles. As in, there is a set of basic gameplay mechanics that let you move and combine tiles, but there are no actual curated interesting puzzle situations, it is all just random chance shapes you have to match. Yes, there is a strategy in managing your empty spaces so you can use it to grow more tiles, but it's just not very interesting.

Even if you manage the empty spaces perfectly. you very quickly clog up your board with unusable tiles due to the fact that they are never removed from the board.

And the random chance shapes vary wildly in size and difficulty and you never know which one you will get next, so you cannot prepare the board for the next one, eliminating one of the potential strategy aspects. You can just get randomly screwed if the game decides to give you something you have no chance of matching.

There should have been more, there should have been pre-made boards with pre-set shapes to match, but as it is, it is just a showcase of game mechanics without a cohesive gaming experience around it. It's like opening solitaire to play a round- and sure, some people like these sorts of infinite timewasters, but I'm not one of them.
