Blast
Blast removes incorrect answer choices returned by the quiz service, narrowing the options for the current question.
Revive
Revive provides another attempt after an incorrect first choice on the current question. The answer is not finalized until the revive flow is resolved.
Swap
Swap requests a replacement for the current question where the game mode and authenticated quiz session support it. A replacement may be unavailable if no suitable question remains.
Reveal
Reveal identifies the correct answer for the current question. It is intended as an in-round aid, not as a public question-bank feature.
Inventory and availability
The Play screen shows the current inventory count and disables power-ups that cannot be used. The live interface is the source of truth for current availability and any coin or reward costs.
