As with the previous iteration of the CCC Classical Cup, the top-8 engines from the CCC24 Rapid tournament will be competing in a double-elimination bracket, playing 16-game matches in the 30+5 classical format.

This event will be run as a series of 16-game matches (due to technical limitations). If one player scores 8.5 points before the conclusion of the match, the remaining games may continue to be played. If the engines are still tied after the 16 games, additional 16-game matches will be played at gradually reduced time controls. Those time controls will be 10+3 (Rapid), 3+2 (Blitz), and finally 1+1 (Bullet). The Bullet event will repeat until a winner is determined.

The top-6 seeds come directly from the CCC24 Rapid: Semifinals Event. Those engines are: Stockfish, Obsidian, Leela, Torch, Berserk, and Dragon. The remaining two engines are seeded from their placement in the CCC24 Rapid: Main Event. Those engines are PlentyChess and Caissa.

For newer watchers, opening books are used to ensure that engines do not draw every game. If allowed to play from the starting position, draws would be ubiquitous. In order to remedy this, unbalanced openings are chosen, where one side (typically White) has an advantage. In order to maintain fairness, the engines will play a game-pair. In one game they will play the advantaged side, hoping for a win. In the next game they will play the disadvantaged side, hoping to maintain a draw.
