@thegoliath thank you for your feedback, we're glad you like Video Poker!
The Double Up option is a simple coin flip, so it's possible to get the same result several times in a row. The same situation is with Roulette (if you skip "0"), betting on black/red you can hit a series of numbers in the same color. In our games, as in other casinos, the outcome of each individual bet is random and there is no "series rule", so bet value, time spent at the table or other similar factors do not matter - each spin is a unique outcome and always remains random.
