The guide

Overview

Code 420 invites players into a thrilling battle of wits, where crafting a secret code and unraveling your opponent's remains central. Engage in strategic clue-sharing and deduction to outsmart rivals. This mental tug-of-war sharpens critical thinking and offers exhilarating fun with friends in an immersive tabletop setting.

Some games never needed updating. Chess has been chess for centuries, solitaire for a couple of them, and the arcade classics of the eighties still play exactly as well as they did. A session with one of these is calm and familiar. You know the rules, you know the rhythm, and the only variable is how well you play today. That is enough.

How to play

1Pick a game mode or difficulty if the start screen offers one, then let the board or deck load.
2Move by clicking or tapping a piece and then its destination. Many games also support drag and drop.
3Take your time. Classic games rarely include a clock unless you turn one on.
4When a game ends, look at the score or move count and try to beat it next round.
