I have played this game daily for years, recently it stopped giving credit for finished puzzles, then it started freezing on me, usually at the end of a game, but last week it started freezing the screen in the middle of game, a few times I uninstalled and installed it again, but it was still a frozen game and no way to fix it without the developers wanting personal info from me. I always played offline, so there were no ads, but ads would still try to play. Uninstalled for good today.

The day of first download, nearly no ads. Second day, an advert after every round and they're the long sneaky ones. This does not make this a relaxing or fun game. Then, once the relentless ads get on your nerves, you see the pay to remove ads banner....but it is only to remove ads for a limited time, then you have to pay again. Sneaky, sneaky, not for me. Don't recommend unless you love overplayed and poorly made ads.

Game has become bogged down with ads over the years. If you tend to finish levels quickly, you'll spend more time seeing ads than playing the game, as there is an ad following every level, with extremely rare exceptions. As a matter of fact, over half of the ads take so long, it is literally faster to close out the game and reopen it, as there is no option to skip these.
