How JetX Works
A jet launches and a multiplier rises with it until the jet explodes at a point decided when the round starts. Cash out first and your stake is multiplied by whatever the counter showed. Leave it and the round takes the lot.
JetX Compared to Aviator
The mechanic is the same curve, and both give you two bet slots per round. The difference is presentation and the shape of the curve, which climbs differently and so rewards a different cash out habit. If you already play one, the other needs no learning.
Auto Cash Out
Set a target before the round rather than deciding while the number is moving. That single setting is the difference between a plan and a reflex, and it is available on both bet slots at lol44.
