Gameplay & Strategy Achievements
Juggler: Play 20 Daily games simultaneously. You can accept 20 games and then abort them after earning the achievement. 
Chess Marathon: Play a game with over 100 moves. This is more common in high-rated games, but you can also arrange this in a friendly unrated match. 
Nick of Time: Win a game with less than a second left on your clock. Bullet games are ideal for this achievement. 
Full House: Win without losing any of your pieces (except pawns). Achieving this against high-rated players is challenging; it's often attained during the beginner phase. 
Castle Victory: Deliver checkmate by castling. This is one of the toughest achievements. You may need to trap your opponent's king in the center and then castle. Alternatively, you can arrange this in a friendly match. 
Killer King: Deliver checkmate by moving your king. Capture all your opponent's pieces, trap their king, and move your king to deliver checkmate. This setup requires careful planning. ( you can ask your friend to let you checkmate them with a king in an unrated friendly match)
