It's a fun, simple game to kill time with. There just needs to be an option to remove ads. Popping up every now and then is fine for a free game but they're to the point of tediousness in their frequency in this game. Ads in between each match, during gameplay, for every hint or button press. Nothing fun about being on the process of moving a piece into place and to have a full screen ad pop up. Especially ones that make you play a few rounds of whatever is being advertised. Plus they're the type of ad that if you click anywhere on the screen other than the tiny "X" to close the ad (which moves to a different spot each ad) it opens the App Store and sometimes the devs website. A simple, easy to find (none currently on the main menu of the game) option to pay to remove ads would greatly improve the experience.
