About This Game

Password Not Valid is a chaotic party game for up to 4 players where each player has to build their own password in an environment where the rules never stop changing.

Write your password

It's easy at first, but before you know it, your password has to have as many vowels as numbers, uppercase consonants, a symbol at the end, Roman numerals, and other crazy requirements...

Choose your rules

The rules aren't random; players take turns changing them. The rules are the same for everyone, so be careful when choosing an easy rule. You'll be making life easier for your opponents too!

Outsmart your friends

To win, your system must be the last one standing. Matches are chaotic: even when all hope seems lost, a single rule or a stroke of luck can turn the tables. There will also be votes to choose the next twist of events (and there's always someone voting for the option that messes with you the most).

Crack other passwords

If your password isn't good enough and your system ends up falling into a hacker's hands, at least you can still try to figure out the passwords of the remaining players... And if you do, you'll attack their system.

Password Not Valid rewards those who know how to read the board, follow the rules, and find a string of characters good enough to defend their system.

Gather up to three friends online and find out who is best at bringing order to the chaos.
