A fun game

It’s a card game called ‘Zero21 Solitaire’ it’s a fun game. I play with my dad.

Recomendación

Los anuncios son DEMASIADOS, aburre tener que estar viendo para poder seguir jugando, y eso en lo particular prefiero salir del juego y ya no continuar jugando.

Too many ads

It’s a fun game but the ads are literally so ridiculous that I deleted the game. No matter if you choose “ad for 5X the diamonds” or not…. You still have to watch an ad. It’s so annoying.

Excessive ads

I wanted to like this game. I’ve seen the ads for it. But I started playing … played one game 15 seconds had a long ad. Came back played another game had a long ad. I don’t think this would be fun in the long-term to watch all these ads more than playing the game.

Mismatch between developers

I downloaded this game thinking it would be okay because it was by Zynga games, but this doesn’t feel like a Zynga game. It feels like a Playrix game instead. The amount of ads doesn’t match the number of ads in the Harry Potter match-3 game by this developer, which has ads but not very many. It matches the amount of ads in the Playrix game Pull the Pin which has ads after every round and in order to claim anything gained through progress. Please reduce the amount of ads in this game to a level similar to the level of ads in your other games.
