How to Play In Sync
Description
No talking. No signals. Just a hundred cards and the hope that everyone is thinking the same thing. Play them in order — or lose everything.
Objective
Play every numbered card in the group's hands in ascending order, together, without ever discussing what you hold.
Setup
Deal each player a hand of cards numbered 1 to 100.
Agree whether to play in silent mode, where all communication is forbidden, or open mode, where talking is allowed.
Rules
Any player can lay a card at any moment — there are no turns.
If a lower number is still sitting in someone else's hand when a card is played, the round fails.
The only way through is instinct: sensing when your card is the lowest remaining, without anyone saying so.
Winning
When the group senses someone is stuck, any player can request a laser beam. Every player must agree, or it isn't used.
If approved, each player's lowest card is automatically removed, clearing the blockage.
Rounds grow harder as the level climbs. Lose all your lives and the game ends; complete every level and the group wins together.
