This started as a really fun game, stringing numbers and completing levels, it is just a nice relaxing game to play. Unfortunately the ads ruin it. Yes you can pay $4.99 and go ad free but it wouldn’t really be add free because you still need the gems and to get them for free… yes, you have to watch ads.
The thing is with these ads is that you have quick ads, then you have slow repetitive ads that last upwards of 45 seconds. You play for a minute, then you get an ad break. Why do these developers put ads in the middle of games, I get the start and the end but when you are into it, it just breaks your focus and quite often I end up just putting my phone down.
One last irritation. As you go up levels, the numbers just become insanely high for no reason at all. Also it will tell you at the top what the next number in the sequence is but unfortunately it is often wrong and therefore just annoying and unhelpful. You also will rarely get the numbers you need to finish the level, so you have take the option of paying gems to combine numbers just to complete the level, so your not really beating it, just paying to clear the round, but if you don’t pay to clear the round, you would never complete it because the numbers won’t come up to be able to do so.
