Keno and lotto: two games, one “lottery” search

U.S.-style keno often draws 20 from 80 while the player marks 2–10. Korean Lotto 6/45 first prize is C(45,6)=8,145,060. Similar-looking digits, different matrices. powerball-vs-mega-millions-odds is two U.S. jackpots. Tonight’s keno rule is the operator. Saju does not pick a space.

Matrices change

Ball counts, draw size, and price are posted. This sketch is not a lifetime table.

Pay tables

Keno pays by catch count; lotto uses rank tables. EV needs each table.

Split from scratch

Printed pools are scratch-card-expected-value.

Responsibility

Fast repeats accelerate losses. Entertainment budget only.
