Plain-language terms
Play fair. Keep learning.
SumSpark is a free educational game. Guest play does not require an account.Using SumSpark
You may use the game, Practice Lab, training plans, and Math Workbench for personal and educational practice. Do not try to disrupt the service, impersonate another player, automate ranked results, or bypass one-attempt challenge rules.
Names, profiles, and shared challenges
Choose display names, usernames, challenge names, and profile text that are appropriate and do not violate another person's rights. Shared links and visible profiles can be viewed by anyone who receives the URL. SumSpark may reserve names or remove abusive public content.
Scores and availability
Leaderboards and challenge standings are recreational. Anti-cheat checks reduce obvious manipulation but cannot guarantee competition-grade verification. Features may change, become temporarily unavailable, or lose unsynchronized browser data.
Optional synchronization
Cloud synchronization is optional. Merge rules favor non-destructive histories and stronger records, but you should export important data before deleting an account or clearing browser storage.
No professional advice
SumSpark is an educational practice tool, not a grading, diagnostic, financial, or professional assessment service. It is provided without a promise that every feature will always be available or error-free.
