The hard level is the Lord of the Sands, the fifth and strongest ruler of the desert kingdom. At this level the computer always plays its best move and searches deeper, so every mistake is punished. It may think up to four seconds on a phone. A clean win over the Lord of the Sands without undo or hints earns the most glory and a trophy, Flawless victory, in the Hall of Trophies.
How to play
The goal is to checkmate the enemy king: attack it so that it has no safe square, no piece can block the attack and nothing can capture the attacker. White moves first, then the sides take turns. Tap a piece and then its square, or drag it; possible moves glow on the board. Castling, en passant and promotion are all in, every kind of draw counts, and the game says in words why a move is not allowed. Undo is free, and three hints a game show a good move.

Questions about Chess
What is checkmate?
The king is attacked, it cannot step to a safe square, no piece can block the attack and the attacker cannot be captured. The game ends at once.
What is the fastest checkmate?
Two moves for Black, as in this example: 1. f3 e5 2. g4 Qh4 checkmate. It only happens when White weakens the king's side.
Can I play two players on one device?
Yes. Choose Two players and pass the phone or share the computer; the board turns to the side whose turn it is.
