This puzzle game is perfect for killing time. If it's been a while since you had a math class, (like me), this can help sharpen your skills. The puzzles are solved using basic math, but figuring out the "rules" make it interesting. The hints are obscure enough that they don't give you the answer, but point you in the right direction. I have the pro version, and I highly recommend it to everyone.

I bought the premium version, but after it stopped, I still get ads, no hints for certain levels, and have to wait to be able to skip. Fix it or give me a refund.
