Build your dream island, house, theme park and more. Eight mystery items. Twenty dollars each. Only four can be yours.
Ten characters appear one at a time. Send five to attack and five to defend, then see if your team survives the final showdown.
Choose 1–6 themed rounds, with six sealed cases each time. Keep or swap, reveal all outcomes, and earn a final letter grade.
Pick a topic, choose 2–10 slots, and rank surprise picks as they appear. Every placement is final—no moving things later!
Will the next thing rate higher or lower? Choose Classic or Game Show Mode with jackpot streaks, power-ups and dramatic reveals.
How well do you know each other? Play Classic or Party Mode with bold bets, impossible choices and secret Double-Meld bonus rounds.
Compete across 3, 5, or all 6 games. Each game earns championship points. One trophy at the end.

MixnMayhem is a free, browser-based party-game website. You can contact the team about privacy and other enquiries at admin@mixnmayhem.com.
Our games use browser storage to remember player names, scores, achievements, favourites, game settings, sound preferences and unfinished games. That information is stored in your browser rather than in a MixnMayhem online player account. Other people using your device or browser profile may be able to see it.
You may clear this information using available in-game record/save controls or your browser's site-data settings. Deleting it may permanently erase game progress.
When you visit this website, the hosting service may process technical information such as your IP address, the time of access, pages requested, and security events to deliver the site and protect its infrastructure.
How long those logs are kept and where they are processed depends on the live hosting setup. For questions about hosting-related information, contact admin@mixnmayhem.com. We will review this notice when hosting is configured or changed.
The current game code does not include advertising cookies or third-party analytics scripts. It uses local browser storage for game features and preferences. The hosting provider may set necessary cookies or use other storage technologies. We will update this notice if analytics, adverts or further technologies are introduced. Where the law requires consent or an opt-out, we will provide appropriate controls before using those technologies.
If you email admin@mixnmayhem.com, we receive your email address, message, and any information you choose to include. We use it to respond to enquiries and deal with necessary follow-up. We intend to keep correspondence only as long as reasonably needed for those purposes, or as required by law. We do not operate public chat or user uploads.
MixnMayhem is designed for recreational play, including families. It does not currently require player accounts or dates of birth. Please avoid entering sensitive or identifying information in custom theme fields or player names. We will reassess children's privacy implications if we add tracking, advertising, or social features.
Depending on the circumstances and applicable law, you may have rights to access, correct, erase or object to processing of personal information, and to complain to the UK Information Commissioner's Office (ICO) at ico.org.uk. The site operator cannot access game data held only in your browser; you can remove that data on your device.
We may update this policy when hosting, game features or data practices change. The latest version will be available on this page.

Character abilities, power ratings, “best” and “worst” lists, house rankings and game judges are subjective entertainment features. They are not official rankings, endorsements or authoritative statements about any person, team, franchise or product. Some factual statistical comparisons are dated snapshots and may become outdated.
Game money, points, badges, grades, trophies and achievements are fictional. They have no monetary value, cannot be redeemed or transferred for cash or goods, and are not gambling stakes or real-world prizes. No purchase is required to play the current games.
Custom themes and player names are entered at your discretion and normally remain in local browser storage. Do not enter private personal information, abusive material, or content that violates others' rights. You are responsible for the content you choose to enter.

The games are provided for entertainment without a guarantee of uninterrupted or error-free operation. Local game saves can be lost through clearing browser data, switching devices, private browsing, software updates or storage restrictions. We do not currently provide cloud backup.
Nothing in these terms excludes or limits liability that cannot legally be excluded or limits any mandatory consumer rights. Subject to applicable law, we are not responsible for avoidable losses arising from relying on entertainment ratings as professional advice, or for loss of locally stored progress.
