Gift X applies a Christmas sleigh theme to a crash-style round. One or two wagers can be placed, and the player collects their corresponding gifts before Santa leaves the flight. Automatic cash-out assigns a chosen multiplier to that collection, while autoplay controls later rounds. The gift illustration should not be mistaken for Open It!'s repeated-click boxes: here, the meaningful event is leaving the rising-multiplier sleigh before the round ends. An unreached automatic target leaves the active wager exposed to that ending.

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