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.

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.

I've played this game for 8-10 years. I expect ads in a free game, but the amount of pop-up, in-game ads have increased over time to the point that it's not enjoyable anymore.The developers snap back to all of the criticism that it's necessary,but they're running off users. I'm going to delete this game, even though I've gone through all of the countries and have solved nearly 11,000 puzzles. I'm fed up with the greed that makes the game so frustrating and not at all relaxing. Badly done.
