Keno in Ultra Monster has separate fans. Choose your bet and it will raise your win amount and you can choose up to 10 numbers. After choosing the numbers 20 keno balls are drawn randomly and displayed in the winning number box. Any of them will be counted as Hits if matching the picked numbers. The winning amount depends on picked numbers and hits quantity. 4 from 20 drawn numbers are marked with shamrock. Any 2,3, or 4 numbers marked with shamrock trigger 5,10, or 15 free games respectively if matching the picked numbers.
