Truco Game (Paulista and Mineiro) 100% free. No frills, no ads, no data collection. You can play individually (against 3 bots) or with up to four people, via Bluetooth or the Internet (experimental). The game does not "steal" - the cards are 100% random and the "bots" cannot see your cards or those of other people playing. This can be audited in the game's code, which is open and available at http://github.com/chesterbr/minitruco-android
