This is, as others have noted, a very fun and addictive game. That said, it gets very frustrating when the game tells you there's 1 pair remaining, you go back thru the entire board and delete a whole bunch of pairs, and when you check again it still tells you there's 1 pair remaining. I understand that removing one pair can result in additional pairs appearing, but this is beyond that.The things this game needs have already been mentioned (hint button, ability to save and return to games, fix bugs that change numbers on the board or where numbers reappear after they've been taken off). This is a solitaire game; there's no reason to make it harder than it already is.

I’ve tried to see how this game is supposed to be any more fun than match-three games. Yes, I can identify two matching numbers. Yes, I can add up to 10. Where’s the strategy? What am I missing? The rules are completely barebones, and my board gets left with massive gaps that are only irritating, making me scroll up and down and up and down. Maybe it isn’t supposed to be that way and my game is just bugged.Also, “haters”? Really? I’m not sure if your native language is English, but using the word “haters” to refer to your confused customers makes you sound like a whiny child, and the explanation that follows it doesn’t even make sense. I paired up a 1 and a 9, and plenty of 9s continued to appear. Whatever this so-called rule from the first game is, it needs to be explained in this second game. I didn’t buy your first game, and after all this? I don’t intend to—whether you whine that I’m a “hater” or not.

I love this game and am addicted to it. That said, I wish there was an undo button. Maybe it could be an in-app purchase as well as a way to earn more, such as one Undo for a certain amount of lines that are cleared or something. Also a hint button would be extremely helpful tool. Same concept as undo.

In an apparently recent update, after I match 2 numbers which then empties a full line of numbers, the lines then realign in a herky-jerky fashion. I HATE this! This completely alters the way I have been looking at lines and numbers, so I then have to refocus, again and again, as numbers disappear. This refocusing interrupts the flow of the game, which in turn interrupts my pleasure at playing the game. I noticed this change a few weeks ago and finally am writing about it because I’m considering NOT playing any more due to this change. I have played this daily for a few years, really enjoying it, but these jerky moves are frustrating and hard on my eyes. I envision some geeks trying to figure out ways to improve the game—-which is NOT needed—- and they ended up choosing this alteration as a result. Bad move.
