How are 101 Okey penalties calculated?
An opener scores the face value of each tile left in hand. A player who never opened receives 202. A real okey left in hand adds its face value plus 101; a false joker scores the indicator's face value.
Finishing on the okey and a true clean finish each double the result. A losing pairs-opener, or a winner who opened with pairs, adds one more doubling. House rules vary; this calculator follows Game Finale's 101 rules.
