Tips and tricks
- On mobile, tilt controls feel exciting but touch buttons are usually more precise. Try both before you settle.
- Nitro or boost is best used on straights where you are already stable, not to rescue a bad corner.
- If the game has upgrades, put the first ones into handling or brakes rather than top speed — control wins more races than raw power at the beginning.
- Traffic and rivals are predictable: they hold their line. Plan your overtake two cars ahead rather than reacting to the one in front.

We would recommend Zero21 to anyone who enjoys speed, vehicles and shaving seconds off a personal best. In terms of time, think of a single race of one to three minutes, or a longer career if unlocks are involved. How hard is it? Forgiving on early tracks, demanding on later ones. The controls are tap and drag based, which makes it comfortable on touch screens as well as with a mouse.
