Oh Hell rules

Predict exactly how many tricks you will take.

Play Oh Hell

How to play

  1. Four players play seven deals, increasing from one card each to seven.
  2. Reveal trump and bid an exact trick count. The final bidder cannot make the combined bids equal the number of available tricks.
  3. Follow suit; trump beats other suits.
  4. An exact bid scores 10 plus the bid; a missed bid scores zero. Highest total after seven deals wins.
