Puzzle Math: Cross Number Game

I paid to remove the ads, just so that every time the timer runs out I had to watch a long ad to resume or start from the beginning. This is just false advertisement. It should be made clear before the purchase that the ads removal option is not completely removing all the ads. The fact that the developer didn’t make that clear and hid it in this sneaky way means they are deliberately defrauding the customers.

Idk if I’m missing something lol, but what are the coins for? I can’t see where I can buy something with them, I can’t buy hints unless it’s with real money, so what am I earning coins for? If I’m missing I’d love to know. I never click the video that multiplies the coins you earn after a round because why would I? There’s no incentive. Otherwise I love the game and I hope the gamemakers are planning on making it more challenging.

I love math. This puzzle game is reawakening my brain what l used to do much quicker 60 years ago in high school. I still have the skills, just a little slower. Thank you for this game.
