When you include Decrypto: Expansion #01 – Laserdrive to the base game, each round you draw a category card — movie titles, tourist attractions, words that begin with an A, etc. — and at least one of the clues that you provide to your teammates must match this category. If all three of your clues match the category, then you get a red laser token.
You can spend two red laser tokens to try and guess one of the team's hidden words. If you guess right, you get a white token because you've intercepted their information — and obtaining two white tokens wins you the game, so this expansion offers you a new way to work toward victory.
