About the game
A new Japanese expansion pack for the game 3 Second Try. The expansion adds 15 new cards with new challenges themed around Osaka. In 3 Seconds Try, players face either physical or brain challenges in under 3 seconds to score the most points. The first player (called "Master") chooses a "Physical" (Dexterity) or "Brain" challenge and reveals the card. Placers bet on how many times they think they can do the challenge in under 3 seconds, and the highest bidder gets to do the attempt. If they can complete the challenge before the ball reaches the end of the slope they win the card. If not, the next highest bidder gets to try the challenge. The first player to earn 2 cards wins. —description from the publisher
