Nintendo is ending Mario Kart Tour as of 11 September 2026.
The mobile game started in 2019 supported by high expectations.
There will be no longer offline option for players.
Players are unable to claim any leftover purchases when it goes dark today.
Nintendo says expenses and limited returns forced the move due to weak revenue.
The game made about $290 million over launch has a substantial fan base.
Fans are upset with the decision and express their frustration.
