Z:gnu-eliot--1d4f12-In a joker game, each rack con/en

In a joker game, each rack contains a joker. When a word containing the joker is played on the grid, the joker is then replaced with the corresponding letter from the bag, and the joker stays in the rack. When the corresponding letter is not present in the bag, the joker is placed on the board. This variant, particularly interesting in Duplicate mode, is good to train using the joker.
