Mario Tennis: Power Tour - Reflex Rally

To promote Mario Tennis: Power Tour, the minigame was remade as an online Flash game that appeared under the name Mario Tennis: Power Tour -- Reflex Rally in the Nintendo Arcade, a section with promotional web games on Nintendo's official website.

From a gameplay standpoint, there are no major differences between the two versions, although the timer in the Flash version starts counting from 30 instead of 60 seconds as in the original minigame. There is also no set score to beat, and the player always controls Clay.
