It's a simple time killer that takes a a tiny bit of thinking. In the early/easier levels you'll definitely be spending more time viewing advertisements than playing (Definitely one of the factors that turned me away, but the developers got to make money somehow). The gameplay itself is pretty straight forward and quite repetitive, but some people enjoy that. You can expect an advertisement every 2-3 levels. I personally found quite dull with the puzzles providing lack of contrast or difficulty.

After the first 5 levels, you get 20 seconds of ads after every level. There seems to be about a 20 sec window of cool down between ads so if you complete two levels within 20 seconds, you're basically guaranteed to hit another ad. If it takes longer than 20 seconds to beat a level, you will get an ad no matter what, and it's about 7 seconds of ads, then followed by 5-10 seconds to close out of it. This game forces you to watch ads as much as you're allowed to play.

Developing mathematical reasoning skills is believed to boost productivity and combat cognitive decline.

Whether you love or loathe math, give this game a shot.
