CheckmateLeague is a skill-based chess competition platform built around gameplay, training, tournaments, leagues, and reward-based features.
Welcome to CheckmateLeague. By creating an account, accessing the platform, purchasing coins, entering competitions, joining leagues, using training features, or using any related service, you agree to these Terms of Service.
CheckmateLeague is intended to be a skill-based chess platform. Game outcomes are based on player decisions, not random chance.
“CheckmateLeague,” “we,” “us,” and “our” refer to the CheckmateLeague website, games, tournaments, leagues, training tools, creator-related promotions, and related services.
The platform may include freeplay, play-a-friend matches, tournament play, league systems, training modes, cosmetic items, creator promotions, reward pools, and other competitive or community features.
You must be at least 18 years old to create an account, purchase coins, enter coin-based features, participate in rewards features, or request a rewards withdrawal.
You are responsible for ensuring that use of the platform is lawful where you live. Accessing the platform from a location where any feature is restricted is done at your own risk.
You are responsible for your account, login credentials, wallet details you submit, and all activity that occurs under your account.
You may not share accounts, sell accounts, create deceptive accounts, impersonate another person, or allow another person to compete on your behalf.
We may require email verification, age checks, security review, or other account checks before granting access to certain features.
Coins are platform balance units used for supported features on CheckmateLeague, such as eligible entries, supported competitive features, store purchases, and other in-platform uses we may offer.
Coins are not withdrawable. Purchasing coins gives you access to in-platform use only. A coin purchase does not create a bank account, custody account, or redeemable cash balance on the platform.
We may add, remove, or change how coins are used across the platform at any time.
Separate from coins, the platform may award an eligible user a rewards balance through reward pools, league placements, daily rewards, weekly league rewards, season results, creator payouts, promotions, or other reward features.
Unless we state otherwise for a specific feature, only your rewards balance may be submitted for withdrawal. Coins themselves are not withdrawable.
Rewards withdrawals currently require a valid Base network wallet address and are paid in USDC on Base. The current minimum rewards withdrawal is 10 rewards.
We may delay, reject, reverse before submission, or review a withdrawal request if fraud, cheating, abuse, account issues, compliance issues, or technical problems are suspected.
Coin purchases and reward-related blockchain payouts on CheckmateLeague use USDC on the Base network unless we clearly state otherwise.
You are responsible for entering the correct wallet address, using the correct network, and sending the correct token and amount when making a blockchain payment.
Blockchain transactions are generally final and irreversible once submitted. We are not responsible for funds sent to the wrong address, wrong network, wrong token, or for losses caused by your wallet provider or blockchain congestion.
Platform pricing, coin packages, tournament structure, creator offers, and supported fees may change at any time.
Coin purchases are generally final. We do not promise refunds for unused coins, match results, tournament entries, missed events, or user mistakes such as sending the wrong amount or token.
Some tournaments or features may have no entry fee, reduced fees, seeded prize pools, or promotional terms depending on how that event is configured.
CheckmateLeague may offer tournaments, league seasons, daily reward pools, weekly reward pools, season prize pools, creator freerolls, and similar competitive programs.
We may set event schedules, late registration windows, ticket requirements, prize structures, eligibility rules, minimum contribution rules, membership-age rules, and rollover rules.
Rewards or placements may be adjusted, delayed, canceled, or denied if an event is affected by cheating, fraud, technical failure, insufficient participation, duplicate accounts, or rule violations.
The platform may offer creator-linked promotions, including creator codes, freeroll tickets, creator dashboards, or creator payout features.
Promotional tickets may expire, may be limited per purchase, may be single-use, and may only be valid for specific events.
We may suspend, deny, or remove creator benefits if abuse, manipulation, fraudulent activity, self-dealing, fake traffic, or rule violations are detected.
Using chess engines, bots, scripts, outside move assistance, account sharing, coordinated outcomes, exploit abuse, manipulation of platform systems, or any other unfair method is prohibited.
If we believe cheating, abuse, fraud, or platform manipulation has occurred, we may suspend or terminate the account, cancel results, deny rewards, remove balances, block withdrawals, or permanently ban the user.
You are responsible for maintaining a stable internet connection, compatible device, and working browser or app environment.
We are not responsible for losses, missed entries, failed joins, incomplete games, or missed rewards caused by internet failure, wallet issues, browser issues, device issues, outages, delays, or third-party service interruptions.
We may decide how to resolve interrupted matches, inactive games, timing issues, stuck events, or technical disputes in a way we believe protects platform integrity.
Training modes, hints, engine analysis, coaching-style prompts, evaluation tools, or practice bots are provided for educational and entertainment purposes.
We do not guarantee that training feedback will always be available, complete, or error-free.
We may suspend, restrict, or terminate access to the platform at any time for violations of these Terms, suspicious activity, fraud risk, security concerns, abuse, harassment, non-payment issues, or legal reasons.
If an account is terminated for cheating, fraud, or abuse, some balances, rewards, or platform privileges may be forfeited to the extent allowed by law and platform policy.
To the fullest extent permitted by law, CheckmateLeague is provided on an “as is” and “as available” basis. We do not guarantee uninterrupted access, uninterrupted blockchain settlement, or error-free operation.
We are not liable for indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of profits, lost opportunities, blockchain errors, or third-party wallet failures.
We may update these Terms from time to time. Updated Terms become effective when posted, unless a different date is stated on the page.
Continuing to use the platform after an update means you accept the revised Terms.
