Mario Kart 8 is a racing game: you choose a Nintendo character and a vehicle, then drive around a course against other racers or the clock. A drift lets you slide around a bend while keeping speed. If you hold that slide long enough, colored sparks appear by the rear tires. Let go of the drift button when you see them and the kart shoots forward for a moment. This guide is for the original Wii U version released in 2014, not Mario Kart 8 Deluxe on Switch. You need the game, a Wii U and a Wii U GamePad or Pro Controller; no paid downloadable course is required.
The shortest answer is: hold A to accelerate, hold ZR as you steer into a corner, and keep ZR held until blue sparks appear. Release ZR for a short Mini-Turbo. If the corner is long enough, keep holding until the sparks turn orange, then release for a longer Super Mini-Turbo. Do not stare only at the buttons; the pictures and steps below show where to look on the course and on the kart.
