Classic Chess is a free iPhone application developed by Cross Field Inc. It is a user-friendly chess app that provides easy-to-understand explanations of the rules. Whether you are a beginner just starting out or someone looking to brush up on the rules, this app is highly recommended.

One of the standout features of Classic Chess is its AI with a wide difficulty level range. From beginner to advanced, the AI is equipped to cater to players of all skill levels. The finely divided difficulty levels allow for a better sense of progression. Additionally, the developers have promised to include even stronger AI levels in future updates.

Classic Chess offers both 3D and 2D modes. In the 3D mode, players can enjoy the game with beautiful graphics, immersing themselves in the atmosphere. The 2D mode, on the other hand, provides clear piece information and makes it easy to keep track of the war situation. This flexibility allows users to choose the mode that suits their preferences.

The developers have also outlined an update schedule, which includes adjustments to the direction and operation feeling, addition of CPU AI, and implementation of additional functions such as ranking.
