CLEAR RULES BEFORE YOU PLAY
Competition rules.
Useful comparisons depend on a shared challenge and honest limits.
Register for ranked play
A confirmed email account is required for public ranked competition and account progress sync. Request a six-digit sign-in code by email; codes expire after ten minutes. Sessions last 12 months. Your generated nickname is public; your email is not. Free play and local records do not require registration.
One game, one level, one period
Rankings separate every game and Chill, Standard or Expert challenge level. Daily and weekly runs use fixed shared starting boards and UTC competition periods. All-time results use a 180-day retention window. Raw scores from different games are not combined into a competitive ranking.
Replay checks and their limits
Ranked play uses a server-issued ticket and a defined input protocol. Recorded inputs and simulation ticks are submitted, and the server recomputes the result. Client-reported raw scores are not accepted as proof. Replay checks do not establish that a human played: bots, shared devices and account misuse cannot be ruled out.
Location is optional and self-selected
A network-based suggestion may show an approximate country, region or city. It can be inaccurate, particularly with VPNs and mobile networks. Manually choose a country, region or settlement, or omit location. The selector uses GeoNames records and verified source chunks; it does not request GPS or certify residence.
Regional rankings need participation
Country, region and settlement tables require at least five participating accounts in the matching competition. A locality with fewer participants does not receive a published regional table. A missing table does not mean nobody lives or plays there. Qualifying hubs contain real results rather than duplicated place-name landing pages.
Team averages
Regional teams are groups of participating accounts that selected the same location. A team needs at least five participants. Scores are averaged within the same game, level and competition period, instead of adding every score or mixing games. Location selection and account counts are not verified population statistics.
Connection and storage
Ranked tickets, submission, account sync and new results require an internet connection. Flight mode keeps saved free-play game files available in the same browser; it does not submit offline play automatically as ranked results. Browser storage can be cleared or evicted.
Support and account control
Use the community page to sign out or delete your account and associated public results. Deleting an account does not clear local progress or offline files already held by your browser. Use the contact form for assistance. Never send a sign-in code, password or complete progress export.
