★★★★★

Jean Oakes

Because of my eyesight I needed high contrast notes. The developer added it to his to-do list and now I can play much easier! Awesome!!

★★★★

Thomas Rosset

Love the game but there's a bug that bothers me quite a bit... Currently, when you click for a hint in a competitive game, it sets the timer to 5 minutes instantly, even if you click away from the hint without using it. So sometimes I just use a hint for nothing and lose time. I would also suggest leaving the choice to the user to highlight all of the same number (including the notes) when selecting a number on the grid.

★★★

Cindy Wallace

This is an awesome game! However, your new ad format has me taking you down to three stars. I don't mind the ads, but they are way too long. I would happily pay for the game if you gave me the option of paying one time, not a recurring charge. Even with how good this game is, it's not worth paying money every month for it. Charge me a few bucks once and I'm in.

★★

Gabriel Costa

The game is amazing, but I think you need to rethink your business model. I understand the recurring costs of leaderboards, but I honestly don't care about the social features. If I could pay you once to play the game as it was a while back, but with no leaderboards, I would do that. Paying monthly for a feature I don't use at all is not a option for me. The limitation on checks and how many times I can play the daily challenges made the game unplayable for me.
