I enjoy the game concept and have found it quite addictive but enough of all the adverts. also the game has reset to zero without me knowing why!!!! despite the ads, I have played this so much, because I enjoy the mental challenge, it has reset to zero twice. also, tournament - what prizes/bonuses? other challenges - what bonuses?? = No Development just vehicle for adverts for unsuspecting clients who don't realise what a limited audience

I'd 100% prefer number sum by daily word. When you get the correct line, it deletes the ones that aren't used in the line. This one you have to delete them yourself, which can be hard, especially when your tired. The only reason I tried this is because daily words app has been playing up a little lately for me. But I'd much rather play anything else rather than this. Sorry but it's true,

Having an advert after each round was bad enough but having just had 2 during a single round I have uninstalled it. I like the game but the scoring and levels might as well be random, there doesn't seem to be any sense of progression. I looked into paying to remove the ads but it wanted me to agree to accept before even telling me how much it would cost.

Hello! Thank you for your review. It's a pity the ad experience was so frustrating that you had to uninstall the game. We do offer an option to remove them for a fee, but before you see the price, you may have to accept Google's terms. However, you're never charged without explicit confirmation beforehand. We'll share your comments with the team.
