This is yet another just OK example of a game that is trying to fill the void left by Megatouch being too stupid to realize the potential of coming out with an official Megatouch Card game for mobile devices. The first company that comes out with a bundled set of multiple card games that have the SAME rules and scoring as the old 90s bar games of Zip 21 (like this), or Run 21, Poker scramble, 11-Up, etc. will make a lot of money. It would be the first, and probably only, game I would gladly pay for. And that would stay on my phone for more than a month. Again, this game is not bad by itself. But since it will obviously be played most by people fondly remembering their alcoholic days in the 90s and 00s, it will just feel like a let-down. Especially since you can't WIN. That was the main sense of accomplishment. CLEARING the board. This deprives you of that by being an endless run.

Good version of the ubiquitous "Run 21" game, but docked a star for constantly yammering at me to sign into Google Play Games every time I play... should be something selectable in the "options" menu.

Too many ads If u click to get out of one ad, when u click on a new game another ad would pop up. Then the Google games would pop up.

Liked the game at first, timer is ridiculous, it was fun, at least 90 times, I got either a 21 or a blackjack, however 20 times their upcoming card put me in a nasty bustable situation. I heard that from Catch 21. I uninstalled it because I was in peril of being shutout of points. They're supposed to give good cards, so you can score. I tried finding 21 Blitz, having trouble with that.
