About

Cambio is a quick memory card game. Everyone gets four face-down cards and peeks at two of them once. On your turn you draw, then swap the card into your hand or discard it. Some discards have powers: peek at your own card, spy on an opponent, or swap blind. When you think your total is the lowest, call Cambio: everyone gets one last turn, then the cards are revealed and the lowest score wins.

How you can play

• Against computer players: on solo tables every seat except yours is a computer player.
• Some seats are filled by system bot players.
• Pass & Play: 2–6 people share one phone. A privacy screen hides the cards between turns.
• As a guest or registered player: registering is free and unlocks custom rulebooks.

Who it is for

Cambio is for adults (18+). It is free: there is no paid tier and no real-money play. Ads pay for it.

Setup screens work upright. The game itself is played with the phone sideways (landscape), and you can install Cambio as an app.
