From the developer:
MURDL is a multi-board word puzzle. You can solve 1-8 simultaneous word puzzles. The same guess is applied to each puzzle board. To win, you must solve each puzzle board with the fewest moves. You can suspend game and resume it at later date. You can review and analyze old games using support dictionaries.
