Chesball is a type of collective chess game. The game is designed to work out the principles of synchronizing the simultaneous creative work of a large number of people in a team. The rules contain the author's description of the game Chesball. For those who are passionate about playing chess. We play Chesball. We are interested in the technology of intellectual activity for the unhindered all-round development of the human personality while simultaneously working in parallel with many creators within the framework of one project; we want to know: what qualitative advantages are possible in this case?; we want to study the spiritual conflict of personal creative freedom and the will of the collective mind; to see how often breathtaking works of chess art are created, bearing the imprint of drama, insights and delusions.
