Chess practice

Syberchess is a free app for chess practice and recreation. It does not require a subscription, payment, or account. Training exercises are learning aids, and no particular chess rating, tournament result, or speed of improvement is promised. Objective product descriptions and any rights or remedies required by law remain unaffected.

Syberchess adapts the artwork into outlines, applies team colors, and adjusts its positioning and size. The copyright notice, license terms, and disclaimer are included with the app. No endorsement by the artwork's author or contributors is implied. Third-party components remain subject to their respective licenses.
