I strongly dislike the TRIPLE obfuscation of paying on this game. You need to buy stamina to play more than a few rounds per day. The stamina is purchased via blue crystals which is purchased by paying for red crystals - all of which ahve different values to trick the end user into not knowing how much they're paying for things directly. This is shady practices and uninstalled immediately after figuring this out. These types of garbage cost hiding has no place on my phone, tablet, or any device
