Welcome, Candidates. For our 5th anniversary, Octopus Game is returning to its roots: the relentless tension of our original Squid Game theme. The objective is no longer just to navigate the massive scale of DEF CON; it is to survive it. We have partnered with the Noob Community to forge a high-stakes arena out of the chaotic conference floor, creating a mandatory initiation process that guarantees every player starts on the same level, yet perilous, playing field.

To endure Octopus Game 5: Revenge of the Squid, you must step out from behind your screen and prove your worth in the physical world. Candidates will decode cryptic ciphers to hunt down hidden NFC tags across the venue, reporting directly to the Guards to secure their standing. But the true threat lies in the Assassin Protocol. You will carry physical Life Tokens at all times, turning simple childhood playground games—like Rock-Paper-Scissors—into ruthless psychological battles against rival players. Protect your tokens, trust carefully, and build your alliances if you want to make it out alive.
