JetX is SmartSoft's original crash flight with two independently placed wagers per round. Each wager can be cashed out manually or assigned its own automatic multiplier target. The flight may end before that target, including at the opening multiplier, in which case the active wager loses. This original two-bet format should be kept separate from the later New Era of JetX interface. Round history and chat describe previous results and player activity; they do not reveal the next explosion point.

The library also explains how crash and instant-game rounds differ to help put these mechanics in context.
