There's a bizarre restriction in Mario Kart 8 Deluxe when playing in Wireless Play mode

Nintendo added a strange limitation to Mario Kart 8 Deluxe when playing it in the two-player Wireless Play mode.

Mario Kart 8 Deluxe supports several different play modes on the Nintendo Switch, thanks to the console's portable nature.

The game can be played with a pair of Joy-Con controllers, a single Joy-Con controller held horizontally, or a Pro Controller. Two players can also play in split-screen via the Wireless Play mode, but there's one restriction you'll have to keep in mind.

As reported by Polygon, the option for each player to use a pair of Joy-Con controllers is greyed out. Your other option is for each player to use one Joy-Con controller - horizontally, or for each to sync their Pro Controllers.

It's not entirely clear why Nintendo put this limitation in place, but it could be due to the Bluetooth bandwidth being used when the console is in tabletop mode. The Switch clearly supports simultaneous controllers to be connected, but the number, and features, vary from game to game.

Mario Kart 8 is out April 28 on the Nintendo Switch.
