Chess.com offers every new account a one-time free 7-day trial of its top-tier Diamond membership, giving full access to unlimited puzzles, detailed game review, opening explorer and every other premium tool.

From the Membership page, select “Try for $0.00” under the Diamond plan to begin – a payment method is required to verify your account and prevent abuse of multiple trials, but you will not be charged if you cancel before the 7 days are up.

Each account is only eligible for one free trial; starting a further membership afterwards begins a paid subscription immediately rather than another trial period.
