A critical hit is an attack that deals increased damage because it triggered a special success condition, usually a random chance or a precise hit location. Most games mark it with larger numbers and a distinct sound.
The basic model has two values: critical chance, the probability an attack crits, and critical damage, the multiplier applied when it does. A common setup doubles damage on a crit, so a hit for 100 becomes 200. Builds that stack chance and multiplier together scale fast, which is why designers cap one or both in competitive games.
Not every crit is random. Shooters and action games often award crits for hitting a weak point, such as a headshot or an exposed core, which turns the crit into a test of aim rather than luck. Tabletop inspired games take the older route: in Dungeons and Dragons a natural 20 on the attack roll is a critical hit, and many video game RPGs inherited that dice logic even after the dice became invisible.
Crits shape how fights feel. A steady stream of normal hits reads as grinding progress, while a sudden crit that removes a large chunk of health creates a turning point. Players remember the crit that finished a boss far longer than the fifty ordinary hits before it.
