Unhonest rating system, loads of cheaters, makes you addicted to trying to up your score but as soon as you do that you get matched up against super strong players with scores that dont match their skill level at all, or just a computers that completely crush you. Bad app inside and out, use other ones. You need to pay to play challenges and even if you pay for a GOLD membership you only get a few challenges per day, you need to pay A LOT of money to play as many puzzles and challenges as you want. Feel very scammed.Severly regret getting a membership with them.-Gold Chess.com member
