All In is an achievement in The Witcher 3: Wild Hunt.

To obtain it, one must play three hero cards in one round of gwent and win the match.

Tips

• It's important to note one has to play the three hero cards in a single round, not throughout the match.
• It is easiest to verse random gwent players not in a quest, as they can be found throughout the game and cost as little as 1 to bet against, although if trying to complete this achievement during a gwent secondary quest, such as High Stakes, make a save prior to the match, and reload if you don't have three hero cards placed and won.
• The Mysterious Elf card does not count towards this as the achievement requires the hero cards one plays to be on their own side of the board to win.
