At Deltaworks, we believe that young thinkers need mental playgrounds where they can learn to create, control, and organize their thoughts. To address this need, we've spent more than 15 years developing effective thought problems, puzzles, and brain teasers for chess. Our most significant contribution is our unique method of instruction: Deltaworks (DEfine the problem, Learn the fundamentals, Take the "mental trip", and have a healthy Attitude). As a method of learning, Deltaworks has already helped many young thinkers along their individual paths towards brilliancy (see AWARDS and LESSONS for more details).
