Championship Player takes a maximum of 66 seconds per turn and plays extremely strongly. When the bag is empty, Championship Player optimally solves endgames in a second or two if the optimal line of play ends the game in three plies or fewer. Speedy Player takes less than a second per turn and is a good opponent to play against if you are in a hurry. Twenty Second Championship Player is a Championship Player that takes only 20 seconds to play, so is a suitable opponent if you're in a semi-hurry.
The "Ask Championship Player for Choices" button ignores the current choices in the Choices tab and invokes Championship Player on the current rack, replacing the current choices with Championship Player's top-ranked choices. Championship Player chooses its moves based on a 2-ply simulation except when there are 1 or 2 tiles in the bag, in which case it recursively solves the preendgame.
When you run a simulation, after each iteration the expected win percentage of the play is estimated and shown in the Choices tab. This win% estimate is most accurate in the beginning and middle of a game. We recommend 2-ply simulations for one's general analysis.
To play through a real-life game with Quackle, and you don't know your opponent's racks, make his or her player be of type Human with Unknown Racks.
